In php, you can use the str_split() function to split the string into an array. This function splits a string into an array according to the specified length.

The str_split() function can split a string into several substrings according to the required length, and combine these substrings into an array.

Syntax format:

str_split(string,length)

• string Required. Specifies the string to be split.

• #length Optional. Specifies the length of each array element. The default is 1.​

<?php
$str="Hello";
$arr=str_split($str);
var_dump($arr);
?>

<?php
$str="Hello";
$arr=str_split($str,2);
var_dump($arr);
?>

If length is less than 1, the str_split() function will return FALSE.

<?php
$str="Hello";
$arr=str_split($str,-1);
var_dump($arr);
?>

If length is greater than the length of the string, the entire string will be returned as the only element of the array.
