Regex help

Hi,

I want to find my link within the html string. currently I’m using this:

$url_to_find = "domain.co.uk";

if(preg_match('#<a.+?href=[\\'"]http://(www\\.)?'.$url_to_find.'[\\'"].+?>#i',$html,$matches))....

which works well for the exact url:

but doesn’t for a subpage link:

http://www.domain.co.uk/subpage.html

How can I modify this code to allow for any links within the domain?

$html = <<<FIL
<a href="http://www.domain.co.uk"></a>
<a href='http://www.domain.co.uk/subpage.html'></a>
FIL;
$url_to_find = "domain.co.uk";

$url_to_find = str_replace('.', '\\.', $url_to_find);

preg_match('#a[\\s]+href[\\s]*=[\\s]*(?:\\'|")(http://?(www\\.)' . $url_to_find . '.*)(?:\\'|")#i',$html,$matches);
var_dump(preg_last_error());
var_dump($matches[1]);

if you want all matches use preg_match_all
if you really want to explore regular expression I would advise downloading Kodos it’s a god send
