What is the difference between the functions split() and preg_split() in PHP?

The main difference between the functions split() and preg_split() in PHP is that split() is deprecated as of PHP 7.0 and removed in PHP 7.3, while preg_split() is the recommended function for splitting strings using regular expressions. Therefore, it is recommended to use preg_split() for any string splitting operations involving regular expressions in PHP. 

// Using preg_split() to split a string using a regular expression
$string = "Hello World";
$parts = preg_split('/\s+/', $string);
print_r($parts);
