# str_split

(PHP 5 CVS only)

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.

Przykład 1. Example uses of str_split()
`<?php $str = "Hello Friend"; $arr1 = str_split($str); $arr2 = str_split($str, 3); print_r($arr1); print_r($arr2); ?>`

    Array
    (
        [0] => H
        [1] => e
