Description:
------------
Maybe there is a reasoning beyond this. However, unexpected output is
produced with ltrim and rtrim if the string has a palindrome-'like'
structure.

Reproduce code:
---------------
$str = 'daobcd';
echo ltrim($str, 'dao')

$str = 'daoabc';
echo ltrim($str, 'dao') /

$str = 'bcsedeo';
echo rtrim($str, 'deo');

Expected result:
----------------
1. bcd

2. abc

3. bcse

Actual result:
--------------
1. bcd

2. bc

3. bcs
