str_split

(PHP 5, PHP 7)
Convert a string to an array
array str_split ( string $string [, int $split_length = 1 ] )

Converts a string to an array.

Parameters:
string

The input string.

split_length

Maximum length of the chunk.

Returns:

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.

Notes:

str_split() will split into bytes, rather than characters when dealing with a multi-byte encoded string.

Examples:
Example uses of str_split()
<?php

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

?>

The above example will output:

Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
    [5] =>
    [6] => F
    [7] => r
    [8] => i
    [9] => e
    [10] => n
    [11] => d
)

Array
(
    [0] => Hel
    [1] => lo
    [2] => Fri
    [3] => end
)
