str_split --  Convert a string to an array

Description

array str_split ( string string [, int split_length])

Converts a string to an array. If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length.

FALSE is returned if split_length is less than 1. If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element.

<?php

$str = "Hello Friend";

/* Output may look like:
