(PHP 5, PHP 7)
str_split — Convert a string to an array
str_split ( string $string [, int $length = 1 ] ) : array
Converts a string to an array.
string
The input string.
length
Maximum length of the chunk.
If the optional length parameter is specified, the returned array will be broken down into chunks with each being length in length, otherwise each chunk will be one character in length.
false is returned if length is less than 1. If the length length exceeds the length of string, the entire string is returned as the first (and only) array element.
Example #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); ?>
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
)
Note:
str_split() will split into bytes, rather than characters when dealing with a multi-byte encoded string.
