Question

function strip_cdata($string)
{
    preg_match_all('/<!\[cdata\[(.*?)\]\]>/is', $string, $matches);
    return str_replace($matches[0], $matches[1], $string);
} 

I use the above function to extract text from cdata, but I don’t know how to modify the reg expression to get a number from the url below.

http://blah.somesite.com/anytextcouldbehere/2828842087.html

Specifically, I need to get “2828842087” from the above url. It will always be numbers and be between the last “/” and “.html”.

Thanks

No need to use regexp here:

$url = 'http://blah.somesite.com/anytextcouldbehere/2828842087.html';

$data = parse_url($url);
$number = basename($data['path'], '.html');
