Leg uit, want de content van een plaatje kun je niet scannen...
daar wil ik op controleren heb het eerder gezien maar weet niet meer waar
De functie fileinfo_file() doet dit. Je moet echter wel die library geinstalleerd hebben. Maar deze methode is dus ook niet bulletproof.
Ik heb verder ook wel eens gezocht naar een andere oplossing maar die is er niet. Wat je evt wel nog zou kunnen doen is proberen er een image object van te maken mbv imagecreatefromjpeg() oid. Deze zal falen als het plaatje niet correct is gok ik. Ik weet niet zeker of deze methode werkt aangezien ik 't nog nooit getest heb.
