the check_jpeg function listed above has a small "bug" when u set $fix=true... after the fix, the function does not close the file... and the imagecreatefromjpeg would still crash on an open file. //# [070203] //# check for jpeg file header and footer - also try to fix it function check_jpeg($f, $fix=false ){ if ( false !== (@$fd = fopen($f, 'r+b' )) ){ if (fread($fd,2)==chr(255).chr(216) ){ fseek ( $fd, -2, SEEK_END ); if ( fread($fd,2)==chr(255).chr(217) ){ fclose($fd); return true; }else{ if ($fix && fwrite($fd,chr(255).chr(217)) ){ fclose($fd); return true; } fclose($fd); return false; } } else { fclose($fd); return false; } } else { return false; } } ---- Submitter IP: 64.246.30.37 ---- Manual Page -- http://www.php.net/manual/en/function.imagecreatefromjpeg.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55340 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55340&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55340&report=yes Search -- http://master.php.net/manage/user-notes.php
