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

The main difference between using split() and preg_split() in PHP is that split() is deprecated as of PHP 5.3.0 and removed in PHP 7.0.0, while preg_split() is the recommended function for splitting strings using a regular expression. Therefore, it is important to use preg_split() instead of split() to ensure compatibility with newer PHP versions and to take advantage of the more powerful regular expression functionality.

// Using preg_split() to split a string based on a regular expression
$string = "Hello,World,PHP";
$parts = preg_split("/,/", $string);
print_r($parts);
