Question

I have the following code

while (strpos($r, "[url]") !== FALSE){
    $link = explode("[url]", $r);
    $final_link = explode("[/url]", $link[0]);

    $thelink = $final_link[0];
}
$r = str_replace("[url]","[url=$thelink]",$r);

If $r = [url]www.google.com[/url], I need to turn this into [url=www.google.com]www.google.com[/url]

This code doesn’t seem to be doing it. Have I missed something?
Give me a 500 error!

Thanks

preg_replace('~\[url\](.*?)\[/url\]~', '[url=$1]$1[/url]', $string);
