</head>
</html>

Solution

You gotta fix this line: $url; = ''; to remove the semicolon after $url. Also, you should echo the result between the <title> and </title> tags, not after them. And lastly, a better structure for your application will be to execute PHP and then output HTML.

<?php
    $url = ''; // <-- insert the URL of choice here, within quotes, starting with http://
    preg_match("#<title>(.*)</title>#Ui", file_get_contents($url), $title);
    $title = substr($title[1],0,255);
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
        <title>
           <?php echo $title; ?>
        </title>
    </head>
</html>
