hey. I need to make file names be consisted of only numbers and letters. Like if there is an image named 'img*1L%^_ove>ly.jpg' it will become 'img1Lovely.jpg' . Only digits and letters (btw letters meaning even if not english letters). Thanks a lot. I went through php.net, failed finding sth like this. Maybe you profies know) or can advise me easy way to do it.
