匹配括号内任何字符的正则表达式

Trying to create a regex that match any character inside a parentheis.

My regex pattern is this

preg_match('/\((.*?)\)/', $listanswer, $answer);

All string inside the parenthesis is the matching pattern. But the problem is, when I try to match eg,. (this word), (sample data) it only returns null. When if no space added, it is matched. Any idea on this?

Already tested it here. http://regex101.com

It worked just fine. Did i miss something>?

    • \( : match an opening parentheses
    • ( : begin capturing group
