What is the difference between using explode() and preg_split() in PHP for string manipulation?

When it comes to string manipulation in PHP, the main difference between explode() and preg_split() is that explode() splits a string by a specified delimiter, while preg_split() uses a regular expression pattern to split the string. If you need more complex splitting criteria, such as using a regular expression, preg_split() is the better choice. However, if you simply need to split a string based on a single character or substring, explode() is more efficient. 

// Example using explode()
$string = "Hello,World,PHP";
$parts = explode(",", $string);
print_r($parts);

// Example using preg_split()
$string = "Hello,World,PHP";
$parts = preg_split("/,/", $string);
print_r($parts);
