In this short snippet you will learn how to trim   using trim() function. To do that you can simply use the trim and the pass in the string to trim as the 1st parameter and 2nd parameter the special character to trim. In this case, it would be "chr(0xC2).chr(0xA0)". For the code implementation do refer to the code example below.

<?php

$key = ' '; // imagine the content of this $key is &nbsp;

$newKey = trim($key, chr(0xC2).chr(0xA0));

if ($newKey === '') {
    echo 'it\'s empty';
}
