replace link from domain and all possible subdomains, regex php

Question

I'm cleaning an html output that contains links to domain and /or subdomains what I reached is to clean all links from main domain with:

$content = preg_replace('#<a href="https?://domain.*?>.*?</a>#i', '', $content);

as you can see here , but, is it possible to create a regex to replace all links from a domain and all its subdomains?

something like:

preg_replace('#<a href="https?://**anysubdomain**.domain.*?>.*?</a>#i', '', $content);

Is this a help? http://stackoverflow.com/questions/4378479/regular-expression-to-get-the-main-domain-of-a-url Look at the best answer ... (And also the comments, it should help you!) — Haudegen, Mar 20 '14 at 09:19

Try this:

preg_replace('#<a href="https?://(?:.+\.)?domain.*?>.*?</a>#i', '', $content);

The above should catch:

<a href="https://domain.com">something</a>
<a href="http://domain.net">...</a>
<a href="http://www.domain.org">...</a>
<a href="http://m.domain.com">...</a>

if the problem is with captures - you should replace it with `(?:.+\.)?` – Uri Agassi Mar 20 '14 at 11:02
replace what? you mean use (?:.+\.)? instead of "" ? – Mark Mar 20 '14 at 11:13

Sorry, I meant `'#.*?#i'` – Uri Agassi Mar 20 '14 at 11:18
I must make more tests, it stills messing but don't know why :( – Mark Mar 21 '14 at 08:52
