PDF 函式

簡介

The PDF functions in PHP can create PDF files using the PDFlib library which was initially created by Thomas Merz and is now maintained by » PDFlib GmbH.

The documentation in this section is only meant to be an overview of the available functions in the PDFlib library and should not be considered an exhaustive reference. For the full and detailed explanation of each function, consult the PDFlib Reference Manual which is included in all PDFlib packages distributed by PDFlib GmbH. It provides a very good overview of what PDFlib is capable of doing and contains the most up-to-date documentation of all functions.

For a jump start we urge you to take a look at the programming samples which are contained in all PDFlib distribution packages. These samples demonstrate basic text, vector, and graphics output as well as higher-level functions, such as the PDF import facility (PDI).

All of the functions in PDFlib and the PHP module have identical function names and parameters. Unless configured otherwise, all lengths and coordinates are measured in PostScript points. There are generally 72 PostScript points to an inch, but this depends on the output resolution. Please see the PDFlib Reference Manual included in the PDFlib distribution for a more thorough explanation of the coordinate system used.

With version 6, PDFlib offers an object-oriented API for PHP 5 in addition to the function-oriented API for PHP 4. The main difference is the following:

In PHP 4, first a PDF resource has to be retrieved with a function call like

$p = PDF_new().

This PDF resource is used as the first parameter in all further function calls, such as in

PDF_begin_document($p, "", "").

In PHP 5 however, a PDFlib object is created with

$p = new PDFlib().

This object offers all PDFlib API functions as methods, e.g. as with

$p->begin_document("", "").

In addition, exceptions have been introduced in PHP 5 which are supported by PDFlib 6 and later as well.

Please see the examples below for more information.

Note: If you're interested in alternative free PDF generators that do not utilize external PDF libraries, see this related FAQ.

需求

PDFlib Lite is available as open source. However, the PDFlib Lite license allows free use only under certain conditions. PDFlib Lite supports a subset of PDFlib's functionality; please see the PDFlib web site for details. The full version of PDFlib is available for download at » http://www.pdflib.com/products/pdflib-family/, but requires that you purchase a license for commercial use.

Issues with older versions of PDFlib

Any version of PHP 4 after March 9, 2000 does not support versions of PDFlib older than 3.0.

PDFlib 4.0 or greater is supported by PHP 4.3.0 and later.

安裝

本 » PECL 擴充功能未包含於 PHP 中。安裝此 PECL 擴充功能的訊息可在手冊中標題為 PECL 擴充功能安裝的一章中找到。更多訊息如新版本，下載，原始文件，維護者訊息以及更新日誌等可以在這裡找到： » http://pecl.php.net/package/pdflib.

To get these functions to work in PHP < 4.3.9, you have to compile PHP with --with-pdflib[=DIR]. DIR is the PDFlib base install directory, defaults to /usr/local.

資源類型

PDF_new() creates a new PDFlib object required by most PDF functions.

Remarks about Deprecated PDFlib Functions

Starting with PHP 4.0.5, the PHP extension for PDFlib is officially supported by PDFlib GmbH. This means that all the functions described in the PDFlib Reference Manual are supported by PHP 4 with exactly the same meaning and the same parameters. However, with PDFlib Version 5.0.4 or higher all parameters have to be specified. For compatibility reasons, this binding for PDFlib still supports most of the deprecated functions, but they should be replaced by their new versions. PDFlib GmbH will not support any problems arising from the use of these deprecated functions. The documentation in this section indicates old functions as "Deprecated" and gives the replacement function to be used instead.

範例

Most of the functions are fairly easy to use. The most difficult part is probably creating your first PDF document. The following example should help to get you started. It is developed for PHP 4 and creates the file hello.pdf with one page. It defines some document info field contents, loads the Helvetica-Bold font and outputs the text "Hello world! (says PHP)".

Example#1 Hello World example from PDFlib distribution for PHP 4


<?php
$p = PDF_new();

/*  open new PDF file; insert a file name to create the PDF on disk */
if (PDF_begin_document($p, "", "") == 0) {
    die("Error: " . PDF_get_errmsg($p));
}

PDF_set_info($p, "Creator", "hello.php");
PDF_set_info($p, "Author", "Rainer Schaaf");
PDF_set_info($p, "Title", "Hello world (PHP)!");

PDF_begin_page_ext($p, 595, 842, "");

$font = PDF_load_font($p, "Helvetica-Bold", "winansi", "");

PDF_setfont($p, $font, 24.0);
PDF_set_text_pos($p, 50, 700);
PDF_show($p, "Hello world!");
PDF_continue_text($p, "(says PHP)");
PDF_end_page_ext($p, "");

PDF_end_document($p, "");

$buf = PDF_get_buffer($p);
$len = strlen($buf);

header("Content-type: application/pdf");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=hello.pdf");
print $buf;

PDF_delete($p);
?>

The following example comes with the PDFlib distribution for PHP 5. It uses the new exception handling and object encapsulation features available in PHP 5. It creates the file hello.pdf with one page. It defines some document info field contents, loads the Helvetica-Bold font and outputs the text "Hello world! (says PHP)".

Example#2 Hello World example from PDFlib distribution for PHP 5


<?php

try {
    $p = new PDFlib();

    /*  open new PDF file; insert a file name to create the PDF on disk */
    if ($p->begin_document("", "") == 0) {
        die("Error: " . $p->get_errmsg());
    }

    $p->set_info("Creator", "hello.php");
    $p->set_info("Author", "Rainer Schaaf");
    $p->set_info("Title", "Hello world (PHP)!");

    $p->begin_page_ext(595, 842, "");

    $font = $p->load_font("Helvetica-Bold", "winansi", "");

    $p->setfont($font, 24.0);
    $p->set_text_pos(50, 700);
    $p->show("Hello world!");
    $p->continue_text("(says PHP)");
    $p->end_page_ext("");

    $p->end_document("");

    $buf = $p->get_buffer();
    $len = strlen($buf);

    header("Content-type: application/pdf");
    header("Content-Length: $len");
    header("Content-Disposition: inline; filename=hello.pdf");
    print $buf;
}
catch (PDFlibException $e) {
    die("PDFlib exception occurred in hello sample:\n" .
    "[" . $e->get_errnum() . "] " . $e->get_apiname() . ": " .
    $e->get_errmsg() . "\n");
}
catch (Exception $e) {
    die($e);
}
$p = 0;
?>

Folks, There is an excellent tutorial from Rasmus Lerdorf available at (It does not support I.E.)



http://talks.php.net/show/osconpdf/



Where PHP Mastermind Guru (Father) explained nicely about text, fonts, images and their attributes with working snippets.



Another tutorial can be found at

Hence following is the various size of PDF Document.



Origin is at the lower left and the basic unit is the DTP pt.



1 pt = 1/72 inch = 0.35277777778 mm



Some common page sizes

For those of us that do not want to pay for a commercial license to use PDFlib I suggest TCPDF:



http://tcpdf.sf.net



TCPDF is an Open Source PHP class for generating PDF files on-the-fly without requiring external extensions. This class is already adopted by a large number of php projects such as phpMyAdmin, Drupal, Joomla, Xoops, TCExam, etc.  



Starting from 2.1 version TCPDF supports UTF-8 Unicode and bidirectional languages such as Arabic and Hebrew.

To get this to work on Windows do not use escapeshellcmd()



From online help:

Following characters are preceded by a backslash: #&;`|*?~<>^()[]{}$\, \x0A and \xFF. ' and " are escaped only if they are not paired. In Windows, all these characters plus % are replaced by a space instead.



So you are probably passing duff paths to pdf2text.exe



Removing escapeshellcmd worked for me. Just make darned sure you are in control of what is being passed through to your system call.

To extend alex's example earlier, you can use a couple of switches inside the pdf doc to give you the total number of pages, without using any ext. I would have added the whole code, however the site keeps on saying "line is too long... yadayada".



Open the doc using fopen("$file", "rb"); (for reading)



Test the first approx 1000b for the following regex

<?php

if(preg_match("/\/N\s+([0-9]+)/", $contents, $found)) {

    return $found[1];

}

?>



If that doesn't return anything, you have to read the rest of the file:



<?php



preg_match_all("/\/Type\s*\/Pages\s*\/Kids\s+

\[.*?\]\s*\/Count\s+([0-9]+)/");



?>



This may return more than one, so look through for the highest value, which is the total number of pages in your doc.

The other issue with DOMpdf is that it has some pretty painful flaws.



You have to supply full paths to everything (images, includes, javascript files, etc).  And boy, do i mean everything.



Even then, it is not 100% sound.  If you have complex sites, it cannot handle it.  It instead breaks the design and only provides you with about a million broken images.



Don't get me wrong, it's GREAT for use with lower-end more simple sites, but if you have a site that say, has a javascript navigation, flash, and a bunch of container divs, it's really not going to do the job.



The above library seems to be the best fit, as about the only way to get high-end sites to work is just to manually write it out yourself using the functions above.



Sorry to bust anyone's bubble.  Good luck.

I seriously tried to get PDF parsing to work to use it in the indexing for fulltext search for a document management. But none of the pdf2text functions below worked for my test cases (among them an openoffice generated pdf file and a file generated by fpdf).



But I found a REALLY WORKING SOLUTION! On linux systems, install the XPDF package. It comes with a tool called pdftotext. Use php code similar to the following to get the text content of your pdf files:



<?

    $file = "test.pdf";

    $outpath = preg_replace("/\.pdf$/", "", $file).".txt";

    

    system("pdftotext ".escapeshellcmd($file), $ret);

    if ($ret == 0)

    {

        $value = file_get_contents($outpath);

        unlink($outpath);

        print $value;

    }

    if ($ret == 127)

        print "Could not find pdftotext tool.";

    if ($ret == 1)

        print "Could not find pdf file.";

?>



The solution works on all test cases and is much more powerful than any of the previous pure php functions posted here, although only available on linux.

http://www.digitaljunkies.ca/dompdf/index.php



PHP5 class that converts HTML to PDF. From the website:

"At its heart, dompdf is (mostly) CSS2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes."

Easiest way to get the text of a pdf is to install xpdf (on redhat yum -y install xpdf) 



then run xpdftotext your.pdf - which will then generate your.txt.

I am trying to extract the text from PDF files and use it to feed a search engine (Intranet tool). I tried several functions "PDF2TXT" posted below, but not they do not produce the expected result. At least, all words need to be separated by spaces (then used as keywords), and the "junk" codes removed (for example: binary data, pictures...). I start modifying the interesting function posted by Swen, and here is the my current version that starts to work quite well (with PDF version 1.2). Sorry for having a quite different style of programming. Luc



<?php

// Patch for pdf2txt() posted Sven Schuberth

        strlen("stream\r\n"),

        strlen($a_data[0])-strlen("stream\r\n")-strlen("endstream"));

            }

        }

    }

I've improved the codesnipped for the pdf2txt version 1.2.

Now its possible the translate pdf version >1.2 into plain text.

Here is a function to test whether a file is a PDF without using any external library.


<?php


define('PDF_MAGIC', "\\x25\\x50\\x44\\x46\\x2D");


function is_pdf($filename) {


  return (file_get_contents($filename, false, null, 0, strlen(PDF_MAGIC)) === PDF_MAGIC) ? true : false;


}


?>


It's not checking if the whole file is valid, just if the correct header is present at the beginning of the file.

domPDF is also a great PDF creation interface. it basically converts your code to CSS and then builds the PDF from that with the absolute positions, and what not...

I was having trouble with streaming inline PDf's using PHP 5.0.2, Apache 2.0.54.



This is my code:



<?

header("Pragma: public");

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

header("Cache-Control: must-revalidate");

header("Content-type: application/pdf");

header("Content-Length: ".filesize($file));

header("Content-disposition: inline; filename=$file");

header("Accept-Ranges: ".filesize($file)); 

readfile($file);

exit();

?>

It would work fine in Mozilla Firefox (1.0.7) but with IE (6.0.2800.1106) it would not bring up the Adobe Reader plugin and instead ask me to save it or open it as a PHP file.



Oddly enough, I turned off ZLib.compression and it started working.  I guess the compression is confusing IE.  I tried leaving out the content-length header thinking maybe it was unmatched filesize (uncompressed number vs actual received compressed size), but then without it it screws up Firefox too.  



What I ended up doing was disabling Zlib compression for the PDF output pages using ini_set:



<?

ini_set('zlib.output_compression','Off'); 

?>



Maybe this will help someone. Will post over in the PDF section as well.

I was searching for a lowcost/opensource option for combining static html files [as templates] and dynamic output from perl or php routines etc. And the sooner or later I found out that this was the most stable, 'speedest' and customizeable way to produce usable pdf 's with nice formatting :



1] create html page output [perl-> html output, direct html output from any app or php echo's etc. [sort these html files locally]



2] parse all html [inluding webimages links, tables font formatting etc] to [E]PS files with the perl app : html2ps [as mentioned beneath] 

http://user.it.uu.se/~jan/html2ps.html [sort all ps files by future pdf page positions]



3] use the free ps2pdf/ps2pdfwr linux application 

http://www.ps2pdf.com/convert/index.htm [uses gostscript, ghostview libs and so on etc]

Has great formatting options like headers, footers, numbering etc

[sort pdf files]



4] convert all pdf files to 1 pdf file with : pdftk [pdftoolkit], deliveres optional compressions/encryption, background stamps etc



One should ask why using different scripts :

- combination perl/php is great : perl is speedier at some issues like conversion to ps files in my experience

- ps to pdf is quickier then direct php to pdf [in my exp.!]

- I have total control over every files whenever i change html files as a template I use only editors or other app. for it [online or offline].



p.s. I had to make a opensource solution for creating simpel report analyses that's based on things like :

- first page [name / title / #/ date]

- some static info [like introduction, copyrights etc]

- some dynamic info [outputted from php->dbase queries] combined

with html tags/images etc.



And this all mixed [so seperated in files for transparancy]. Also the 3 way manner : data-> html, html->ps, ps->pdf, is easier and quickier to program or adjust in every step.



Correct me if i'm wrong [mail me to]

After one hole day understanding how pdflib works i got the conclusion that its enough hard to draw just with words to furthermore for drawing a line maybe you will need something like four lines of code, so i did my own functions to do the life easier and the code more understable to modify and draw. I also made a function that will draw a rect with the corners round and the posibility even to fill it ;)



You can get it from http://www.deulos.com/pdf_php.php

Yet another addition to the PDF text extraction code last posted by jorromer. The code only seemed to work for PDF 1.2 (Acrobat 3.x) or below. This pdfExtractText function uses regular expressions to cover cases I have found in PDF 1.3 and 1.4 documents. The code also handles closing brackets in the text stream, which were ignored by the previous version. My regular expression skills are somewhat lacking, so improvements may possible by a more skilled programmer. I'm sure there are still cases that this function will not handle, but I haven't come across any yet...

If you want to display the number of pages (for example: page 1 of 3) then the following code could be helpful:



<?php 

... 



$pdf->begin_page_ext(842,595 , "");

  .. add text,images,...

$pdf->suspend_page("");



$pdf->begin_page_ext(842,595 , "");

  .. add text,images,...

$pdf->suspend_page("");



... create all pages



$pdf->resume_page("pagenumber 1");

... add number of pages to page 1

$pdf->end_page_ext("");



$pdf->resume_page("pagenumber 2");

... add number of pages to page 2

$pdf->end_page_ext("");



...

I found this info about pdflib scope on a Chinese (I think) site and translated it.  I was trying to do pdf_setfont and kept getting the wrong scope error.  Turns out it has to be in the Page scope.  So pdf_setfont will only work when called between pdf_begin_page and pdf_end_page.

How to get how many pages in a PDF? I read PDF spec. V1.6 and find this:



PDF set  a "Page Tree Node" to define the ordering of pages in the document. The tree structure allows PDF applications, using little memory to quickly open a document containing thousands of pages.



If a PDF have 63 pages, the page tree node will like this...



2 0 obj

<< /Type /Pages

    /Kidsn [ 4 0 R

               10 0 R

             ]

     /Count 63        <---- YES, got it

>>

endobj



[P.S]   a  PDF may not only a pages tree node, The right answer is in "root page tree node", if  /Count XX with  /Parent XXX node, it not "root page tree node"



SO, You must find the node with /Count XX and Without /Parent  terms, and you'll get total pages of PDF



%PDF-1.0  ~  %PDF-1.5 all works

I recently tested Donatas' code below for the extraction of text from PDF files.  After running into a few problems where PDF files were not being read at all, I've modified it somewhat.  It still isn't perfect, but should work great for searching.  Thanks Donatas.



<?php

$test = pdf2string("<pathtoPDFfile>");

echo "$test";



# Returns a -1 if uncompression failed

function pdf2string($sourcefile)

{

   $fp = fopen($sourcefile, 'rb');

   $content = fread($fp, filesize($sourcefile));

   fclose($fp);



   # Locate all text hidden within the stream and endstream tags

   $searchstart = 'stream';

   $searchend = 'endstream';

   $pdfdocument = "";



   $pos = 0;

   $pos2 = 0;

   $startpos = 0;

   # Iterate through each stream block

   while( $pos !== false && $pos2 !== false )

   {

      # Grab beginning and end tag locations if they have not yet been parsed

      $pos = strpos($content, $searchstart, $startpos);

      $pos2 = strpos($content, $searchend, $startpos + 1);

      if( $pos !== false && $pos2 !== false )

      {

         # Extract compressed text from between stream tags and uncompress

         $textsection = substr($content, $pos + strlen($searchstart) + 2, $pos2 - $pos - strlen($searchstart) - 1);

         $data = @gzuncompress($textsection);

         # Clean up text via a special function

         $data = ExtractText($data);

         # Increase our PDF pointer past the section we just read

         $startpos = $pos2 + strlen($searchend) - 1;

         if( $data === false ) { return -1; }

         $pdfdocument = $pdfdocument . $data;

      }

   }



   return $pdfdocument;

}



function ExtractText($postScriptData)

{

   while( (($textStart = strpos($postScriptData, '(', $textStart)) && ($textEnd = strpos($postScriptData, ')', $textStart + 1)) && substr($postScriptData, $textEnd - 1) != '\\') )

   {

      $plainText .= substr($postScriptData, $textStart + 1, $textEnd - $textStart - 1);

      if( substr($postScriptData, $textEnd + 1, 1) == ']' ) // This adds quite some additional spaces between the words

      {

         $plainText .= ' ';

      }



      $textStart = $textStart < $textEnd ? $textEnd : $textStart + 1;

   }



   return stripslashes($plainText);

}

?>

<?PHP

/* A little helpful function to calculate millimeters to points */

function calcToPt($intMillimeter) {

  $intPoints = ($intMillimeter*72)/25.4;

  $intPoints = round($intPoints);

  return $intPoints;

}



/* For example: Create DIN A4 210x297 mm */

pdf_begin_page( $pdf, calcToPt(210), calcToPt(297)); // 595x842 pt

I've been looking for a way to extract plain text from PDF documents (needed to search for text inside 'em). Not being able to find one I wrote the needed functions myself. here you go folks.



<?php

  function pdf2string ($sourceFile)

  {

    $textArray = array ();

    $objStart = 0;

    

    $fp = fopen ($sourceFile, 'rb');

    $content = fread ($fp, filesize ($sourceFile));

    fclose ($fp);

    

    $searchTagStart = chr(13).chr(10).'stream';

    $searchTagStartLenght = strlen ($searchTagStart);

    

    while ((($objStart = strpos ($content, $searchTagStart, $objStart)) && ($objEnd = strpos ($content, 'endstream', $objStart+1))))

    {

      $data = substr ($content, $objStart + $searchTagStartLenght + 2, $objEnd - ($objStart + $searchTagStartLenght) - 2);

      $data = @gzuncompress ($data);

      

      if ($data !== FALSE && strpos ($data, 'BT') !== FALSE && strpos ($data, 'ET') !== FALSE)

      {

        $textArray [] = ExtractText ($data);

      }

      

      $objStart = $objStart < $objEnd ? $objEnd : $objStart + 1;

    }

    

    return $textArray;

  }

  

  function ExtractText ($postScriptData)

  {

    while ((($textStart = strpos ($postScriptData, '(', $textStart)) && ($textEnd = strpos ($postScriptData, ')', $textStart + 1)) && substr ($postScriptData, $textEnd - 1) != '\\'))

    {

      $plainText .= substr ($postScriptData, $textStart + 1, $textEnd - $textStart - 1);

      if (substr ($postScriptData, $textEnd + 1, 1) == ']') //this adds quite some additional spaces between the words

      {

        $plainText .= ' ';

      }

      

      $textStart = $textStart < $textEnd ? $textEnd : $textStart + 1;

    }

    

    return stripslashes ($plainText);

  }

?>

Those looking for a free replacement of pdflib may consider

pslib at http://pslib.sourceforge.net which produces PostScript but it can be easily turned into PDF by Acrobat Distiller or ghostscript. The API is very similar and even hypertext functions are supported. There

is also a php extension for pslib in PECL, called ps.

About creating a PDF document based on the content of another document(let's say a text file):



I have tried to send to the PDF-creator page from a link from the sender page the file name of the file I want to read the content from and generate the PDF document containing this content. The idea is is that when I tried to reffer the pdf-creator page via the link your_root/create_pdf.php?filename=$your_file_name, the pdf-creator page does not behave well when before creating the pdf document I have a line like $filename = $_GET["filename"].

I solved this using on the sender page instead of the link a form with a button, so the form has as action "create_pdf.php", as method "post" and a hidden field containing the "filename" value. And it works like this if, on the pdf-creator page I have a line like $filename = $_POST["filename"].



I would like to understand why this way it works and the other way does not.



I hope this helps. Here are the pieces of code I used.



Sender page:

print("<form name='to_pdf' action='see_pdf_file.php' method='post'>");

print("<br/><input type='submit' value='PDF'><input type='hidden' name='filename' value='$filename'></form>");



PDF-creator page:

<?

$filename = $_POST["filename"];

$file_handle = fopen($filename, "r");

$file_content = file_get_contents($filename);

fclose($file_handle);

//

$file_content = wordwrap($file_content,72,"|");

$a_row = explode("|",$file_content);

$i = 0;

//

$pdf = pdf_new();

pdf_open_file($pdf, "");

pdf_begin_page($pdf, 595, 842);

pdf_set_font($pdf, "Times-Roman", 16, "host");

pdf_add_outline($pdf, "Page 1");

pdf_set_value($pdf, "textrendering", 1);

pdf_show_xy($pdf, 'The content of the file:',50,700);

while ($a_row[$i] != "")

{

       pdf_continue_text($pdf,$a_row[$i]);

       $i++;

}

pdf_end_page($pdf);

pdf_close($pdf);

//

$data = pdf_get_buffer($pdf);

//

header("Content-type: application/pdf");

header("Content-disposition: inline; filename=test.pdf");

header("Content-length: " . strlen($data));

//

echo $data;

?>



PDFLib and PHP 431 used.



Thanks.

RedHat 9 + Apache 2.0 + PHP 4.3.2 + Oracle 9i + PDFlib 5.0.1 (binary distribution)



It seems to be a working bundle if you do some magic with ./configure:



RedHat 9:

kernel-2.4.20-18.9



Apache 2.0.46:

./configure --enable-so --enable-rewrite=shared --enable-status --enable-mpm=prefork



PHP 4.3.2:

./configure \

--program-prefix= \

--prefix=/usr \

--exec-prefix=/usr \

--bindir=/usr/bin \

--sbindir=/usr/sbin \

--sysconfdir=/etc \

--datadir=/usr/share \

--includedir=/usr/include \

--libdir=/usr/lib \

--libexecdir=/usr/libexec \

--localstatedir=/var \

--sharedstatedir=/usr/com \

--mandir=/usr/share/man \

--infodir=/usr/share/info \

--with-config-file-path=/etc \

--with-config-file-scan-dir=/etc/php.d \

--without-tsrm-pthreads \    # !!!!!!!!!!!!!!!!!!!!

--with-zlib \

--with-gd \

--enable-gd-native-ttf \

--with-ttf \

--without-mysql \

--with-apxs2filter=/usr/local/apache2/bin/apxs \

--with-oci8 \

--enable-sigchild \

--enable-inline-optimization



Oracle9i:

ln -s $ORACLE_HOME/rdbms/public/nzerror.h $ORACLE_HOME/rdbms/demo/nzerror.h



ln -s $ORACLE_HOME/rdbms/public/nzt.h $ORACLE_HOME/rdbms/demo/nzt.h



ln -s $ORACLE_HOME/rdbms/public/ociextp.h $ORACLE_HOME/rdbms/demo/ociextp.h



If you want to use bundled GD-library then:

1) install following packages: libjpeg, libjpeg-devel, libpng, libpng-devel, freetype, freetype-devel, libtiff, libtiff-devel, zlib, zlib-devel



2) ln -s /usr/lib/libjpeg.so.62 /usr/lib/libjpeg.so

ln -s /usr/lib/libpng.so.62 /usr/lib/libpng.so



It seems to be a working combination, because it is NOT give you:

1) error message in Apache's error_log:

Module compiled with module API=20020429, debug=0, thread-safety=0

PHP compiled with module API=20020429, debug=0, thread-safety=1



2) error message in Apache's error_log:

[notice] child pid 12345 exit signal Segmentation fault (11)



3) MS Internet Explorer can show PDF-output from your PHP-script via Acrobat plug-in and does not crush. No confusing messages about opening "Adobe Acrobat Control for ActiveX".



Hope it will save you some time.



Good luck,

Boris
