str_split — Convert a string to an array
$string
, int $length
= 1): arrayConverts 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, except the final chunk
which may be shorter if the string does not divide evenly. The default
length
is 1
, meaning every chunk will be one byte in size.
If length
is less than 1
,
a ValueError will be thrown.

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. Use mb_str_split() to split the string into code points.
