Question

I am really confused how to word this question. I need to take some portion of string that enclosed in square bracket.
Please see the example

Re: [115] VFA 1 von 04/11/2012 bis 04/12/2012 mit-1221

This is somebody sending as subject of mail. I need to retrieve the number 115 from the square bracket . If there are more than square bracket came , position of this will be first at any point

How could I fix that.

EDIT

I wish could I’ve get all instances of [] in the string
Re: [115] [12] VFA 1 von 04/11/2012 bis 04/12/2012 mit-1221

Thanks

Answer 1

You can do this with regular expressions:

preg_match_all('/\[(\w+)\]/', $str, $matches);
$square_brackets = $matches[1]; // array of: "115", "12"
