What are some potential pitfalls of using the split() function in PHP for string manipulation?

One potential pitfall of using the split() function in PHP for string manipulation is that it has been deprecated as of PHP 7.0. Instead, you should use the explode() function, which achieves the same result of splitting a string into an array based on a delimiter. This will ensure your code remains compatible with newer versions of PHP.

$string = "Hello,World";
$delimiter = ",";
$array = explode($delimiter, $string);
print_r($array);
