php regex : get src value

Question

How do I retrieve all src value using regex in php?

<script type="text/javascript" src="http://localhost/assets/javascript/system.js" charset="UTF-8"></script>
<script type='text/javascript' src='http://localhost/index.php?uid=93db46d877df1af2a360fa2b04aabb3c' charset='UTF-8'></script>

The retrieved value should only contains:

• http://localhost/assets/javascript/system.js
• http://localhost/index.php?uid=93db46d877df1af2a360fa2b04aabb3c

Thank you.

/src=(["'])(.*?)1/

example:

<?php

$input_string = '<script type="text/javascript" src="http://localhost/assets/javascript/system.js" charset="UTF-8"></script>';
$count = preg_match('/src=(["'])(.*?)1/', $input_string, $match);
if ($count === FALSE) 
    echo('not found
');
else 
    echo($match[2] . "
");

$input_string = "<script type='text/javascript' src='http://localhost/index.php?uid=93db46d877df1af2a360fa2b04aabb3c' charset='UTF-8'></script>";
$count = preg_match('/src=(["'])(.*?)1/', $input_string, $match);
if ($count === FALSE) 
    echo('not found
');
else 
    echo($match[2] . "
");

gives:

http://localhost/assets/javascript/system.js
http://localhost/index.php?uid=93db46d877df1af2a360fa2b04aabb3c
