#29594 [Opn]: imagegif gives warning "Unable to open temporary file "

ID: 29594 User updated by: jbrady at sbccd dot cc dot ca dot us Reported By: jbrady at sbccd dot cc dot ca dot us Status: Open Bug Type: GD related Operating System: Windows XP,2003 PHP Version: 5CVS-2004-08-10 (dev) New Comment: Did some testing today. The tmpname support works fine (writes to the c:\windows\temp directory just fine). I used it to create a temporary file, and used imagegif to write to it, then outputed the image, and it worked fine. It seems it just can't create the file on its own (when you omit the optional file parameter). Code used in this test: $strFileName = "http://static.php.net/www.php.net/images/php.gif"; $image = imageCreateFromGif($strFileName); if(is_resource($image)) { $tmpfname = tempnam("",""); // NOTE: // Required to get a picture on Netscape // Comment out to get Error messages header("Content-type: image/gif"); // END NOTE imagegif($image,$tmpfname); imageDestroy($image); $string = file_get_contents($tmpfname); unlink($tmpfname); echo $string; } Previous Comments: ------------------------------------------------------------------------ [2004-08-10 03:12:12] jbrady at sbccd dot cc dot ca dot us Description: ------------ I installed the latest version of php5 (built Aug 10 2004 02:15:17 ). I used php.ini-recommended changing only: display_errors = on extension_dir = "c:\php\ext" extension=php_gd2.dll Tried on Windows XP and Windows 2003. When I use the imagegif() function, it gives me a warning: "Warning: imagegif() [function.imagegif]: Unable to open temporary file in c:\Inetpub\wwwroot\tests\php\imagetest.php on line 6 " It is not a permissions problem. The temporary file functions work, and if I change it to imagejpeg, it outputs the picture, without any errors. Reproduce code: --------------- <?php $strFileName = "http://static.php.net/www.php.net/images/php.gif"; $image = imageCreateFromGif($strFileName); if(is_resource($image)) { // NOTE: // Required to get a picture on Netscape // Comment out to get Error messages header("Content-type: image/gif"); // END NOTE imagegif($image); imageDestroy($image); exit; } ?> Expected result: ---------------- The php logo from the php website. Actual result: -------------- Warning: imagegif() [function.imagegif]: Unable to open temporary file in c:\Inetpub\wwwroot\tests\php\imagetest.php on line 6 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29594&edit=1
