preg_replace() can do lookaheads and lookbehinds, that will do what you want. for example: Bill(?= The Cat| Clinton) will match "Bill The Cat" or "Bill Clinton" Bill(?! The Cat| Clinton) will match Bill as long as it is not followed by " The Cat" or " Clinton" Joe Sheble aka Wizaerd wrote: > > Actually, I guess I left something out, but before I dive into that, this > won't work if it's the first thing in a string because of the space at the > begin of the search pattern... > > BUT, this won't quite work for me because this interferes with legitimate > URLS in the given text. > > If my text is as follows, I only want the URLs that are not already > surrounded by an <A HREF=""> tag to be converted > > $cBlah = "this <A HREF="�b��� > ����http://www.somepage.com">tag</A> would not convert, > but this one http://www.someotherpage.com would > convert..."; > > And the same thing applies to email addresses as well..... > > At 03:34 PM 9/14/00, James Atkinson wrote: > >This should do it, I found it at www.phpwizard.net > > > >function make_clickable($text) { > > $ret = eregi_replace(" > > ([[:alnum:]]+)://([^[:space:]]*)([[:alnum:]#?/&=])", "<a > > href=\"\\1://\\2\\3\" target=\"_blank\" > > target=\"_new\">\\1://\\2\\3</a>", $text); > > $ret = eregi_replace(" > > (([a-z0-9_]|\\-|\\.)+@([^[:space:]]*)([[:alnum:]-]))", "<a > > href=\"mailto:\\1\" > > target=\"_new\">\\1</a>", $ret); > > return($ret); > >} > > > >It'll do email address's and URLS. > > On Thu, 14 Sep 2000, Joe Sheble aka Wizaerd wrote: > > I know I'm real light on the regular expression stuff, and it's my own > > fault, but I'm working under a fairly heavy deadline, otherwise I'd just > > find the answer myself. > > > > I need a regular expression that finds all web URLs in a given string and > > converts it to a clickable link.
