#46242 [NEW]: Ltrim-Rtrim Palindrome Syndrome
From: can at berkol dot net
Operating system: Windows Vista
PHP version: 5.2.6
PHP Bug Type: *General Issues
Bug description: Ltrim-Rtrim Palindrome Syndrome
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
