Alright well I tried solving it by myself, and this is what I came up with. NOTE: I realized that the number I want will always be after the first equals sign (=) and will either encompass the rest of the string or end at the first ampersand (&), so I used those chars instead: [code]if (strpos($referurl, '='))   $startpos = (strpos($referurl, '=')) + 1; if (strpos($referurl, '&')) {   $endpos = strpos($referurl, '&');   $length = $endpos - $startpos;   $topicid = substr($referurl, $starpos, $length); } else {   $topicid = substr($referurl, $startpos); }[/code] So, now my question is, will that code set $topicid to 7383 if: [code]$referurl="http://mydomain.com/forums/index.php?showtopic=7383&pid=59790"[/code] or [code]$referurl="http://mydomain.com/forums/index.php?showtopic=7383"[/code] ?

Oh, and I just realized you may be confused by my request.. I am recieving this url string as input from HTTP_REFER, in a php script that is not "index.php" so I can't just retreive the value of showtopic via $_GET['showtopic']

Ok, so here is what I want to accomplish; I have a string input that is a url which I want to extract the number following the text "showtopic=" and may or may not have text following it, but if it does, it will always be a "&". so for example, I might recieve the following as input: [code]http://mydomain.com/forums/index.php?showtopic=7383&pid=59790[/code] And I want to extract and store the 7383 in a variable such as $topicid. I may also have an input such as: [code] http://guardianhq.com/forums/index.php?showtopic=7383[/code] where I want the same thing returned. How would I go about this? Thanks in advance.
