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

The main difference between the split() and preg_split() functions in PHP is that split() uses a simple string as a delimiter to split a string into an array, while preg_split() uses a regular expression pattern as a delimiter. Therefore, preg_split() offers more flexibility in defining the delimiter pattern. If you need to split a string using a regular expression pattern, you should use preg_split() instead of split().

// Using preg_split() to split a string using a regular expression pattern
$string = "Hello,World,PHP";
$delimiter = "/[,]/";
$parts = preg_split($delimiter, $string);
print_r($parts);
