Question is as simple as that:

What is the fastest way to iterate over multibyte string in PHP?

I suggest the following one:

<?php

$s = "bong-zhoor";

for ($i = 0; $i < mb_strlen($s, 'UTF-8'); $i++) {
    $ch = mb_substr($s, $i, 1, 'UTF-8');

    echo $ch . ' ';
}

Looking for improvements, if any.

Calculate the length of the string just once. – zerkms Mar 06 '17 at 21:41

Do `for($i=0, $c=mb_strlen($s, 'UTF-8'); $i < $c; $i++){}`. Recently made an answer for that [here](http://stackoverflow.com/a/42515276/4982088) – Xorifelse Mar 06 '17 at 21:42
@Ankh `preg_split()` is hardly efficient.. – Xorifelse Mar 06 '17 at 21:42
@Ankh Definetelly a duplicate, but still wanna keep my question because it has more *findable* title when googling. – Denis Kulagin Mar 06 '17 at 21:45
