What are the potential pitfalls of using split() in PHP for array manipulation?

Using split() in PHP for array manipulation can be problematic because it has been deprecated since PHP 5.3.0 and removed in PHP 7.0.0. This means that split() should not be used in modern PHP code as it may cause compatibility issues and errors. Instead, developers should use the explode() function, which serves the same purpose of splitting a string into an array based on a delimiter.

// Using explode() instead of split() for array manipulation
$string = "apple,banana,orange";
$fruits = explode(",", $string);
print_r($fruits);
