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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46242&edit=1
