删除括号内的字符串

Question

Good day!

I would like some help in removing strings inside the square brackets and including the square brackets.

The string looks like this:

$string = "Lorem ipsum dolor<br /> [ Context are found on www.example.com ] <br />some text here. Text here. [test] Lorem ipsum dolor.";

I just would like to remove the brackets and its contents that contain "www.example.com". I would like to retain "[test]" in the string and any other brackets have no "www.example.com" in them.

Thanks!

Use a regular expression something like /\[.*?\]/. The backslashes are necessary, otherwise it will try to match any single character ., *, or ? instead.
