Parameters
-
string
-
The input string.
-
split_length

If the optional split_length

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