Re: PHP function inside a regex - possible?

Thanks Zak, unfortunately the /g modifier doesn't appear to be supported and with the U modifier I get nothing where term2 should be bolded. I have sent a file with some 'real-life' sample text to Andrea, he is going to look at it, his last suggestion worked for him but not for me, he's using a PHP4 snapshot from late March and using PHP4B3. I'm going to build a PHP4RC1 binary now... - Kev Zak Greant wrote: > Hi Kev, > > Try putting a g after the /e in your regex.
