How to do a universal link search using preg_match_all?

Question

PHP

How to find all links that meet the following requirements using one query:
located on the domains mydomain1.com, site.ru, superdomen.org.ru ... the number of domains can be added. Also, the link can be

<a href="_сылка_">...</a>
<a href="_сылка_">...</a>
[url]_сылка_[/url]
[url=_сылка_]...[/URL]

Answer 1

Hello.
It can be like this.
Example
This part is repeated three times
To add another domain, simply use this entry.
We want to add google.com, then to this part mydomain1\.com.*|site.ru.*|superdomen\.org\.ru.* we add through the symbol | this entry: google.com.* And we get:
mydomain1\.com.*|site.ru.*|superdomen\.org\.ru.* |google.com.*
This is not the best option, if you think carefully, you can think of a better volume), but this is one of the easiest ways).

Answer 2

Well, I was able to come up with something like this:

$string = "some text
  [url]http://dvz.local/index/index/regionId/28[/url]
        <a href=\"http://stuff.ru/roadmap_page.php\">wetrwetwert</a> [url=https://192.168.3.192/roadmap_page.php]qqqqqqqqq[/url]
         [URL]http://www.192.168.3.192/roadmap_page.php#qwe[/URL]";
preg_match_all('#(http|https)://([^\s]*)(192.168.3.192|stuff.ru)([^\s]*)#', $string, $matches);

var_dump($matches);

It is easier in terms of adding a new domain, but there is a problem with the ending:

array(3) {
    [0]=>
    string(49) "http://stuff.ru/roadmap_page.php">wetrwetwert</a>"
    [1]=>
    string(54) "https://192.168.3.192/roadmap_page.php]qqqqqqqqq[/url]"
    [2]=>
    string(51) "http://www.192.168.3.192/roadmap_page.php#qwe[/URL]"
  }

Those. the last segment of the link tag remains. How to remove it in the same regular season, so as not to cling to str_replace or preg_replace later. In fact, you need to make cuts for such characters - space, [, (, ", ' . But something doesn’t work out to be tied to the regular expression. How to do it more competently?
A solution that fully satisfies the task.
Thanks to everyone who responded and gave me ideas!
