Description:
------------
if safe_mode on, and fopen, imagejpeg (to file) .. wants to 
write to file that does not exist the file DOES NOT GET CREATED (file/dir permissions OK), but an error gets displayed.

Warning: imagepng(): Unable to access img/test.png in /.../t.php on line 4

Warning: imagepng(): Invalid filename 'img/test.png' in /.../t.php on line 4

Reproduce code:
---------------
<?php
        $img = imagecreatefrompng('img/font.png');
        imagepng($img,'img/test.png') or die('wtf?');
        echo 'test';
?>

Expected result:
----------------
i expect img/test.png to be created and "test" displayed.

Actual result:
--------------
img/test.png does not get created.
imagecreatefrompng() works, but imagepng() fails ,dying with text "wtf?".

--
this code circumvents the bug:
<?php
        $img = imagecreatefrompng('img/font.png');
        touch('img/test.png');
        imagepng($img,'img/test.png') or die('wtf?');
        echo 'test';
?>

1) that works fine for me.
2) you didn't explain at all how exactly you run the script
3) you haven't tried latest CVS snapshot

Thanks for your reply.
i'm running linux 2.4.32 with apache 1.3.34 installed. php is enabled as apache module.
the php file that generates errors is being accessed from the web.
directory structure follows:
./:
t.php  rwxrwxrwx user:web <-- file being accessed
img/  drwxrwxrwx user:web

img/:
[empty]

I've listed the file t.php above.

I have this same EXACT problem.   This is surprising, considering:
- I am using PHP Version 5.2.5
- There have been numerous claims that this was fixed in version 4, and most of the bug reports originate back in 2005 and 2006 (it's now 2008).

Furthermore, neither the touch() and fopen() workarounds work for me, as they seem to have worked for PHP4.

Any help would be appreciated.
