Sample string : ‘123456’ convert it into ’12 34 56′

Introduction

PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following example.

<?php
$str= '123456'; 
echo substr(chunk_split($str, 2, ' '), 0, -1)."\n";
?>

Result
