Inefficient.

$message = preg_replace("<REGULAR EXPRESSION THAT WORKS>", '<a href="\1">\1</a>', $message);



SO PWNS that.  I just need a working regular expression.  I'm shocked none of you have worked with them.  O_o

Well, not so much you, Joe.  You're a VB person =p

<?  echo findurl("ftp://www.test.org str1 http://www.test.com str2 ftp://www.x86labs.org str3");  function findurl($data) {    $ret = "";    $words = explode(" ", $data);    foreach($words as $word) {      if (substr($word, 0, 7) == "http://") {        $ret = $ret . '<a href="' . $word . '">' . $word . "</a> ";      }elseif (substr($word, 0, 6) == "ftp://") {        $ret = $ret . '<a href="' . $word . '">' . $word . "</a> ";      }else{        $ret = $ret . $word . " ";      }    }    return $ret;  }?>

Sidoh, do you always mess up your code?

Know that [ php] is a syntax highlighted tag, so don't expect the bold tag will work in the future.

Additionally, since PHP contains the ability to define variables implicitly, I didn't mess up my code.  It works fine, there's just memory allocated for an array that isn't used.  :P
