Simple question: need help

[Napster]

I am making a forum and I am currently adding it so that users can use my code that I make to do certain stuff like would make the text underlined. I am using str_replace(); The problem i m having is that when I go to do urls it don't work right? How do I fix this? Like all it will do is show the text but not be a link

[Napster]

we if I go $content = str_replace("","<a>",$content); and then I go [url]http://www.msn.com all that will show up in the forum is http://www.msn.com and it wont be a link

You will need to parse the bit between your and tags to get the url to add into your <a> tag as in <a href="theurl">

How would I go about doing that?

$content = str_replace("[url=","<a href='",$content);
$content = str_replace("]","' target='blank_'>",$content);
$content = str_replace("[/url]","</a>",$content);

Rather than use the tagging method why not use a function I wrote to tag up a url in a string.

function tagurl($instring){
		$curpos=0;
		$length=strlen($instring);
		while($startpos=strpos($instring," http:",$curpos)){
			// we have found the beginning of a url
			$startpos++;
			$curpos=$startpos;
			$char = "";
			$url = "";
			while ($char!=" "){
				$char=substr($instring,$curpos,1);
				$url.=$char;
				$curpos++;
				if($curpos==$length) break;
			}
			// we have now got the whole url so replace it with tags included
			$instring = str_replace($url,"<a href=\"$url\">$url</a>",$instring);
			$length=strlen($instring);
		}
		return($instring);
	}

            // example of how to use the func
$test="blah blah blah [url]http://www.soulmatchmaker.com[/url] blah blah cblah [url]http://www.babywelcome.com[/url]";
$test=tagurl($test);
echo $test;
