Get All URLs From Page

Get All URLs From Page

Ever needed to get all the urls from a string or a web page? No? Well, here is a script that will do it anyway. Basically it works on grabbbing anything beginning with http, or https, up to the next double comma " or a space. The results are then returned in an array where you can extract them for your use. 


<?php

$string = '<a href="http://www.example.com">Example.com</a> has many links with
examples <a href="http://www.example.net/file.php">links</a> to many sites and
even urls without links like http://www.example.org just to fill the gaps and
not to forget this one http://phpro.org/tutorials/Introduction-to-PHP-Regex.html 
which has a space after it. The script has been modifiied from its original so now
it grabs ssl such as https://www.example.com/file.php also';
/**
 *
 * @get URLs from string (string maybe a url)
 *
 * @param string $string
 *
 * @return array
 *
 */function getUrls($string)
{
    $regex = '/https?\:\/\/[^\" ]+/i';
    preg_match_all($regex, $string, $matches);
    return ($matches[0]);
}

 $urls = getUrls($string);

 foreach($urls as $url)
 {
    echo $url.'<br />';
 }
?>

The above script will output a list of urls from the string like this..

http://www.example.com
http://www.example.net/file.php
http://www.example.org

https://www.example.com/file.php
