function mb_str_pad( $input, $pad_length, $pad_string = ' ', $pad_type = STR_PAD_RIGHT)

}

There is a feature request in the PHP bug tracker for integrating such a function in the core. Please look at https://bugs.php.net/bug.php?id=21317 and vote for it. Thanks

If you want to provide explicit encoding usage, you can define the function like this:

function mb_str_pad($input, $pad_length, $pad_string = ' ', $pad_type = STR_PAD_RIGHT, $encoding = null)
{
    if (!$encoding) {
        $diff = strlen($input) - mb_strlen($input);
    }
    else {
        $diff = strlen($input) - mb_strlen($input, $encoding);
    }
    return str_pad($input, $pad_length + $diff, $pad_string, $pad_type);
}

If your pad_string is itself multibyte, this still won't give the right result. The tricky part is that str_pad will copy as many bytes out of the pad_string as it needs to reach the pad_length, and will therefore generate corrupt strings. So, basically, you cannot use str_pad unless you first make sure you append too many bytes and then copy the right length out of it via mb_substr.

bad idea as unless the whole string is multi-byte this could lead to issues with string encoding...

Works for me.

Works for me too...
This is the behavior I expected from str_pad.
