It's just a list of characters you want trimmed from the front and end
of a string, i.e.

$str1 = '#*It works *# #* *#';
$str2 = trim($str1, '#* ');
echo $str;

prints "It works"

Be sure to add a space character in case you have one at the end. And
while you can use a regex, it's way overkill for something this simple.
