What are the potential pitfalls of using the split function in PHP?

One potential pitfall of using the split function in PHP is that it has been deprecated since PHP 5.3.0 and removed in PHP 7.0.0. Instead, it is recommended to use the explode function to split a string into an array based on a delimiter. 

// Using explode function instead of split
$string = "Hello,World,PHP";
$delimiter = ",";
$array = explode($delimiter, $string);

print_r($array);
