What is the purpose of using explode without a string separator in PHP?

Using explode without a string separator in PHP can cause unexpected behavior as it will split the string into individual characters. To avoid this issue, you can use the str_split function instead, which will split the string into an array of individual characters. 

$string = "Hello";
$chars = str_split($string);
print_r($chars);
