Simple Regex help, need a minor modification to this

What up friends, I'm using this little function to parse hyperlinks in plain text and convert them into links. It goes like so

private function hyperlink($text) {
		// match protocol://address/path/
	    $text = ereg_replace("[a-zA-Z]+://([.]?[a-zA-Z0-9_/-])*", "<a href=\"\\0\">\\0</a>", $text);
	
	    // match www.something
	    $text = ereg_replace("(^| )(www([.]?[a-zA-Z0-9_/-])*)", "\\1<a href=\"http://\\2\">\\2</a>", $text);
	    
	    // match @replys
	    $text = preg_replace("/[@]+[A-Za-z0-9-_]+/", "<a href=\"http://twitter.com/\\0\">\\0</a>", $text);
	    
	    // match #hashtags
	     $text = preg_replace("/[#]+[A-Za-z0-9-_]+/", "<a href=\"http://search.twitter.com/search?q=\\0\">\\0</a>", $text);
	    
	    // fix Twitter URLs
	    $text= str_replace("<a href=\"http://twitter.com/@","<a target=\"_blank\" href=\"http://twitter.com/",$text);
	    $text= str_replace("<a href=\"http://search.twitter.com/search?q=#","<a target=\"_blank\" class=\"hashtag\" href=\"http://search.twitter.com/search?q=%23",$text);
	
	    // return $text
	    return $text;
	}

...This works great however it doesn't parse URL's that have query strings at the end such as

http://example.com/blah?question=answer

. If somebody could modify it to make it work with those I would be extremely grateful. Also, if it's not to difficult, it would be extremely beneficial to have it parse blip urls in the form

http://blip.com/~7cwjh

Thanks a bunch guys!

Hi.

Check out example #3 in the manual entry for ereg_replace.
Should work for both of your strings.

Cool I'll give that a shot.. I had originally gone there to find the solution, and ended up using the one that is posted 2 down from there as the guy claims the original code was wrong.

I'll try out that code and see how she goes.

Thanks a bunch!

Works like a charm... Thanks!

The PHP manual entries are pretty much always right.
The comments, however, aren't always as dependable.

Anyways, I'm glad you've found a solution :)
