Re: Regular Expression Problem

Even this: $output = preg_replace("/^[\$]{1,2}[a-zA-Z][0-9]+$/", "<b>\\1</b>", $var); echo $output; Doesn't work. It just takes whatever you put into $var, then puts it into $output, and outputs it to the screen. I want to change anything resembling a PHP variable, i.e. $var, $$var or &$var to <b>$var</b>. Any ideas on how to do that? >>> php-general@gremlins.com.hk 07/02/02 01:50PM >>> On Wednesday 03 July 2002 01:40, Martin Clifford wrote: > Hey all! > > I'm trying to get this darn eregi_replace() to work, but it doesn't produce > any results at all. > > I want it to find all occurances of PHP variables.

Try changing eregi_replace to preg_replace. -- Jason Wong -> Gremlins Associates -> www.gremlins.com.hk Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* Reichel's Law: A body on vacation tends to remain on vacation unless acted upon by an outside force. */
