PHP function split

str_split() function

If the optional split_length parameter is specified, each element in the returned array is a character block of length split_length, otherwise each character block is a single character.

If split_length is less than 1, return FALSE. If the split_length argument exceeds the length of string , the entire string will be returned as only one element of the array.

$str = "Hello Friend";

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

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

?>

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
)

The above has introduced the PHP function split, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
