URL To Clickable Hyperlink

[system]

This is the code I’m using for a very simple chat. I’d like to automatically make URL’s clickable when posted. Help please

[php]<?php
if (isset($_POST[“submit”]) && $_POST[“message”] != “”) {
date_default_timezone_set(“America/Los_Angeles”);
$txt = "
<span class=“date”>Captain’s Log - Stardate: “. date(“njy @ giA”) .”
"
. stripslashes(nl2br($_POST[“message”])) . “
”
. "<div class=“line”>
";
$file_data = “$txt”;
$file_data .= file_get_contents(‘txt.txt’);
file_put_contents(‘txt.txt’, $file_data);
}
?>[/php]

You make a url “clickable” by using a a tag with an href, it doesn’t happen automatically.

Find the url in the strings and add the a tag in.
