You shouldn't use regular expressions to parse HTML. Use the DOM instead. — John Conde, Nov 17 '13 at 15:05

Perhaps

'/<link .*?(href=[\'|"](.*)?[\'|"]|\/?\>)/i'

Then you can acces the link with $2

Regex to find hrefs of all stylesheets can be a tricky task. You should consider using some PHP HTML parser to get this information.

You can read this article to get more information and then try this code.

// Retrieve all links and print their HREFs
foreach($html->find('link') as $e)
    echo $e->href . '<br>';

// Retrieve all script tags and print their SRCs
foreach($html->find('script') as $e)
    echo $e->src . '<br>';

PS: Remember, your script tag may not contain a src then it will print empty string.

Not that this is better than the other answer, however just in case you want to see it, I've altered your regex such that it should work as intended:

'/<link.*?href\s*=\s*["\']([^"\']+?)[\'"]/i'
