PHP Convert string to array str_split

Convert a continuous string into a single character array

Example:

<?php
    $str = &#39;abcde&#39;;
    $arr1 = str_split($str);
    print_r($arr1);
?>

The output result is as follows:

Array
(
    [0] => a
    [1] => b
    [2] => c
    [3] => d
    [4] => e
)

The difference from explode is: The first parameter of explode must pass a splitting character (such as:, | space) to split; str_split splits directly
