[PHP] improve turning urls into links routine

[Peter J. Schoenster]

Hi,

I did a quick search for something like this below but did not find it. 

Would you please criticize it. Thanks.

function &MakeUrls(&$data) {
        $words = explode(" ", $data);
        $new_data = "";
        while (list ($key,$row) = each ($words) ) {

                if (preg_match ("/^http:\/\//", $row)) {
                        // should just be the url here
                        $new_data .= "<a href=\"$row\">$row</a> ";
                        continue;
                }

                if (preg_match ("/http/", $row)) {      // catch on the line 
break which I did not explode on
                        $row = preg_replace ("/(http[^\s]+)/","<a 
href=\"\\1\">\\1</a>", $row);
                }

                $new_data .= "$row ";
        }

        return $new_data;               
} # End Get
