PHP Bug Type: mbstring related
Bug description: Two error messages returned for incorrect encoding for
mb_strto[upper|lower]
Description:
------------
When an incorrect or unknown encoding is passed to mb_strto[upper|lower]
two error messages are returned which both are warning about the same
thing.
In some cases, one error message is returned as well as an
upper/lowercased string, but this behaviour is not documented.
Reproduce code:
---------------
<?php
$sourcestring = 'Hello, World';
$inputs = array(12345, 12.3456789000E-10, true, false, "");
$iterator = 1;
foreach($inputs as $input) {
echo "\n-- Iteration $iterator --\n";
var_dump( mb_strtolower($sourcestring, $input) );
var_dump( mb_strtoupper($sourcestring, $input) );
$iterator++;
};
?>
Expected result:
----------------
Only one error message should be returned for iterations 1-3
Actual result:
--------------
