How to get last digits which are number before '.html' string

there is a string, for example : http://address.com/sef-title-of-topic-1111.html

i could not get 1111 in anyway with regexp in php. Is it possible? How?

my code: 

$address = 'http://address.com/sef-title-of-topic-1111.html';

preg_match('#-(.*?)\.html#sim',$address,$result);

If the format is always the same you dont need a regex.

$url = "http://address.com/sef-title-of-topic-1111.html";

echo $str = strrev(array_shift(array_reverse(explode(".", array_shift(explode("-",strrev($url)))))));

edit: sorry my php is a bit rusty

If you know that the extension is definitely .html (and not .htm for example) then you could use

$lastNos= substr($input, -9, -4);

Clearly a simple solution but you have not specified why regex is required.

If the url example is how they will always appear (ie. ending in hyphen, numbers, .html) then this should work:

$str = "http://address.com/sef-title-of-topic-1111.html";

preg_match('#.*-(\d+)\.html#', $str, $matches);
print_r($matches);

If they won't always match the pattern you gave in your question, then clarify by showing alternative values for your $address value.

If the URL will always be in this format I would use str_replace to strip the .html then explode by "-" and find the last piece.

Of course all of that is assuming the URL is always in this format.
