Calling function inside preg_replace

[Porl123]

$string = preg_replace('/\[img\](.*?)\[\/img\]/','<img src="'.validImage('\\1').'" />',$string);

 

I'm trying to make the image tags bb code, but I need to put the link through the validImage function to check that it isn't an invalid image. I'm not really sure how to wrap it though. I think the way I've done it above just analyses the literal phrase '\\1' rather than what it represents. Anyone know what I'm doing wrong? Thanks guys!

You are going to want to look into the e modifier for the preg functions, as it will do the eval.

Ah yeah it's sorted now. :] thanks premiso.
