I spend too much time with session_set_save_handler() but could not use it.

I work with Apache/1.3.12 (Win32) PHP/5.1.2 in local mode, if it matters. I want to use handler destroy() but it does not

work. If I need to determine all handlers, then I have a problem with write().

Function write() does not want to create and open storage file. If file created outside the 

function, it still would not be opened. Actually, write() refuses to create any file. But debug output shows

that write() was called and had all the necessary data.

This problem can be solved by removing of function write(). Session will create storage file and write

data in it. But function destroy() refuses to work in any case. (It's the only function I need.)

After closing of browser the storage file remains and file 

temp (debug output) is absent.

Maybe closing of browser does not mean end of session (although next time the session id will be different), 

but let's see how function write() works:



<?php

function open($save_path, $session_name)

{

  global $sess_save_path;



  $sess_save_path = $save_path;

  echo "$session_name successfully opened<br>"; ////debug

  

  return(true);

}



function close()

{

  return(true);

}



function read($id)

{

  global $sess_save_path;



  $sess_file = "$sess_save_path/sess_$id";

  return (string) @file_get_contents($sess_file);

}



function write($id, $sess_data)

{ echo "write begin<br>"; //////debug

global $sess_save_path;



$sess_file = "$sess_save_path/sess_$id";

  

echo "$sess_file<br>"; ////debug

echo "$sess_data<br>"; /////debug

  

if ($fp = @fopen($sess_file, "w")) 

  {

      $return = fwrite($fp, $sess_data);

      fclose($fp);

      return $return;

  } 

 else 

   { echo "did not open file for writing<br>";  //////debug

      return(false);

   }

}



function destroy($id)  // works in no case

{ 

  global $sess_save_path;

  $f = @fopen("./tmp/temp", "w"); /////debug

  $sess_file = "$sess_save_path/sess_$id";



  return(@unlink($sess_file));

}



function gc($maxlifetime)

{

  global $sess_save_path;



  foreach (glob("$sess_save_path/sess_*") as $filename) {

    if (filemtime($filename) + $maxlifetime < time()) {

      @unlink($filename);

    }

  }

  return true;

}



session_set_save_handler("open", "close", "read", "write", "destroy", "gc");



session_save_path("./tmp"); // temporary storage

session_name("counter");



session_start();



//$id = session_id(); //If I use these 3 strings, file will be created,

//$sess_file = "$sess_save_path/sess_$id"; // but would not be opened by write() all the same.

//$fp = @fopen($sess_file, "w");  // file will be empty



if (!(session_is_registered("someVar"))) // new session

{ echo "someVar not registered<br>"; ////debug

session_register("someVar"); // session variable

$_SESSION["someVar"] = "someValue";

}

echo "it still works<br>"; ////debug



?> 



File temp was not created.

A storage file was not created and output in browser was as follows:



counter successfully opened

someVar not registered

it still works

write begin

./tmp/sess_a4bc6c82ab15635de77bd0c9c74b13d4

someVar|s:9:"someValue";

did not open file for writing



Who could explain this phenomenom?

Here's how I successfully installed PHP 5.2 with my IIS 5.1:



1) Install with the option: "IIS 4+ / ISAPI"

2) Install under folder "C:\PHP\"

3) Edit the file: "C:\WINDOWS\php.ini"

   Change "doc_root = " to "doc_root = c:\inetpub\"

4) Open IIS, right click on home page, properties.

   Click "home directory" tab.

   Click Configuration, look for the extension ".php".

   The executable path should be "C:\PHP\php5isapi.dll"

5) Restart IIS.



Enjoy. I had to learn the hard way. Took me 2 days.
