note 57282 added to function.getimagesize

This function does not work to catch corrupted PNG images. The alternative is to use ImageMagick's identify tool. Due to some sort of odd output usage the output from ImageMagick's identify won't be returned but you can use the return value from the program to test if a PNG file is valid: #!/usr/bin/php <?php if (! $argv[1]) exit("$argv[0] filename.png\n"); $result = 0; $tmp; exec("identify $argv[1]", $tmp, $result); if($result) { echo "Corrupted image\n"; return FALSE; // corrupt PNG file } else { echo "Valid image\n"; return TRUE; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.getimagesize.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57282 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57282&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57282&report=yes Search -- http://master.php.net/manage/user-notes.php
