How can the str_split function be used to convert integers into arrays in PHP?

To convert integers into arrays in PHP using the str_split function, you can first convert the integer into a string using the strval function. Then, use the str_split function to split the string into an array of individual characters. This allows you to work with each digit of the integer separately as elements in an array.

$number = 12345;
$numberString = strval($number);
$numberArray = str_split($numberString);

print_r($numberArray);
