Trying to remove empty braces in a string

Question

I am having a string MyText (text in braces). I am trying to remove spaces at beginning and ending. Also, I want to remove empty braces () like this. For example, if my string is like this MyText (), I have to remove () and print MyText.

My PHP code:

$str = 'MyText (text in braces) ';
echo trim($str, ' ()');

My output is MyText (text in braces It is trimming the outer brace also. But it should not remove that.

Try [`preg_replace('~^\s+|(?:\s+|\s*)$~', '', $s);`](http://ideone.com/JTgWkp) — Wiktor Stribiżew, Jul 07 '16 at 14:06
I think it should be `/^\s+|(?:\s+|\s+\s*)$/g` to trim spaces before empty parentheses. — wazelin, Jul 07 '16 at 14:11
@WiktorStribiżew preg_replace is overkill. For such a simple match str_replace is more than adequate. — GordonM, Jul 07 '16 at 14:24
@GordonM: Unless the `()` must only be removed at the end of the string. — Wiktor Stribiżew, Jul 07 '16 at 14:25

Try this

<?php
    $str = 'MyText (text in braces) ';
    echo trim(str_replace("()", "", $str));
