note 113253 added to function.exif-imagetype

Because I only want to check for jpeg or png from a memory string, this is my 2 functions that are quick and don't have any dependencies : <?php function is_jpeg(&$pict) { return (bin2hex($pict[0]) == 'ff' && bin2hex($pict[1]) == 'd8'); } function is_png(&$pict) { return (bin2hex($pict[0]) == '89' && $pict[1] == 'P' && $pict[2] == 'N' && $pict[3] == 'G'); } ?> ---- Server IP: 195.221.21.36 Probable Submitter: 193.54.50.250 ---- Manual Page -- http://php.net/manual/en/function.exif-imagetype.php Edit -- https://master.php.net/note/edit/113253 Del: integrated -- https://master.php.net/note/delete/113253/integrated Del: useless -- https://master.php.net/note/delete/113253/useless Del: bad code -- https://master.php.net/note/delete/113253/bad+code Del: spam -- https://master.php.net/note/delete/113253/spam Del: non-english -- https://master.php.net/note/delete/113253/non-english Del: in docs -- https://master.php.net/note/delete/113253/in+docs Del: other reasons-- https://master.php.net/note/delete/113253 Reject -- https://master.php.net/note/reject/113253 Search -- https://master.php.net/manage/user-notes.php
