Re: PHP function inside a regex - possible?

Hi, Kevin, As to your example, you have to have the replacement string be suitable for an "echo" statement, I think. The following works, anyway: $newtext = preg_replace("/(<B>(.*)<\/B>)/e", "\"<A href=\" . '\\2' . \"><B>\" . '\\2' . \"</B></A>\"", $text ); Good luck, Andreas kev wrote: > > Zak McGregor wrote: > > > In php 3.x, no.
