mb_str_pad()

This is true multibyte implementation of PHP's built-in string function str_pad() which support UTF-8 both in $input and in $pad_string.

This function is implemented as a static method of MbString class (not as a standalone function) because PHP doesn't doesn't support autoloading of functions on demand. You will not want to include it prior every usage.

Installation

Quite simple: composer require gugglegum/mb-str-pad

Usage

<?php

require_once 'vendor/autoload.php';

use gugglegum\mb_str_pad\MbString;

$input = 'Привет'; 
$pad_length = 20; 
$pad_string = '÷˟‾҈';
$pad_type = STR_PAD_BOTH;
$encoding = 'UTF-8';

echo MbString::mb_str_pad($input, $pad_length, $pad_string, $pad_type, $encoding);

In all cases of using single-byte $input and $pad_string the result will be the same as of built-in str_pad() function.
