Description:
------------
Opening a curl session to non-existing file over the file:// protocol corrupts php's session handler.

Reproduce code:
---------------
<?php
session_start();
$ch = curl_init("file://C:/filedoesntexist.txt");
if ($ch != NULL) {
  $data = curl_exec($ch);
  curl_close($ch);
}
session_write_close();
exit;

Expected result:
----------------
nothing

Actual result:
--------------
Warning: session_write_close() [function.session-write-close]: write failed: Bad file descriptor (9) in C:\apache\htdocs\curltest.php on line 8

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:

Same.
You have to hit refresh a single time to trigger the error.

This code doesn't produce any errors here.
In fact, it doesn't produce anything at all.
 [2006-10-14 13:01 UTC] troelskn at gmail dot com 
You have to reload the page one time to trigger the error. It doesn't happen on first load.
 [2006-10-14 13:09 UTC] tony2001@php.net 
That's what I did.

My bad. I didn't update the extensions dir string in php.ini, so it still used my old php_curl.dll. I tried changing this to use the ext dir of the snapshot, and I disabled all other extensions. Now I get the following error (in apache error log) :

PHP Warning:  PHP Startup: curl: Unable to initialize module\nModule compiled with module API=20060613, debug=0, thread-safety=1\nPHP    compiled with module API=20050922, debug=0, thread-safety=1\nThese options need to match\n in Unknown on line 0

As I couldn't get the snapshot to work with php5apache2.dll, I replaced it with php5apache2_2.dll. Maybe this is the reason why curl fails ?
I'm using apache 2.2.2

Please make sure you've removed all .dll's from the previous PHP installation, including php5ts.dll and reinstall PHP once again.
The error message means that you're trying to load a newly compiled module with old PHP (php5ts.dll).

I tried removing the old installation of php - still the same error.

My old installation of apache/php has the following line in httpd.conf :
LoadModule php5_module c:/apache/php5/php5apache2.dll

This doesn't work with the snapshot. I replaced it with :
LoadModule php5_module c:/apache/php5/php5apache2_2.dll

Does this make any difference ?

>I tried removing the old installation of php - still the same error.
Which one of the two?

>This doesn't work with the snapshot. 
"doesn't work"? I don't think I understand this..

>Does this make any difference ?
Of course it does, Apache 2.0.x and Apache 2.2.x are two different Apache versions.
