Remove Code from String and get Values

Question

I want to remove this code

[gallery columns="2" link="none" ids="69,50" orderby="rand"]

from a string. The [gallery .....] is always the same and the ... changes. How can I do this? Then I want to save the ids value in another string. What is the most elegant way? Thank you.

The following Regex will match the whole string to remove it, and will contain the ids in an extracted group:

/\[gallery .*?ids="(.*?)".*?\]/

This code should work:

$string ='test i am test lol [gallery columns="2" link="none" ids="69,50" orderby="rand"] me also!';
preg_match('/\[gallery .*?ids="(.*?)".*?\]/', $string, $matches);

echo $matches[1]; // prints the ids

$string = preg_replace('/\[gallery .*?ids="(.*?)".*?\]/', '', $string);

echo $string; // prints the cleaned string

This is perfect! Thank you very much! I did not find a good manual to understand this stuff: /[gallery .*?ids="(.*?)".*?]/. Can you tell me how it is called so I can search for it?
