Detection - the title of the URL and the URL

Question

How to detect, if there is any URL in the text and title it has (if any)?

If there is one, then it should change the URL:

from: http://stackoverflow.com

into:

<detected:url="http://stackoverflow.com"/>

I need also to retrieve titles from external links like this example:

<title:http://stackoverflow.com/="the actual title from the stackoverflow"/>

This depends. Do all URLs start with "http?" What indicates a URL's title? — Explosion Pills, Sep 30 '11 at 23:44
@tandu Not really because it will parse the data that user posted. Title is the detected site url title from tags. — Lucas, Sep 30 '11 at 23:46
@Lucas just a question. Why did you prefix this question with "PHP" ? — genesis, Sep 30 '11 at 23:50
@genesis-φ Because I need to add that to my PHP function. All should be PHP so I think it's a good prefix. — Lucas, Sep 30 '11 at 23:52

This is for single URL case:

$url = "http://www.stackoverflow.com/";

$check_result = get_detected_and_title( $url );


function get_detected_and_title( $url )
{
    $detected = '<detected:url="'.$url.'"/>';
    $title = '';
    $tmp_html = file_get_contents( $url );
    preg_match('/<title>(.*)<\/title>/', $tmp_html, $res);
    $title = '<title:'.$url.'="'.$res[1].'"/>';

    return array( $detected, $title );
}

Actually, after looking through SO's pages, I think this is more close to what you looking for. Although it needs some adjustment: How to mimic StackOverflow Auto-Link Behavior
