What are the differences between the PHP functions split and explode, and when should each be used?

The main difference between the PHP functions split and explode is that split is deprecated as of PHP 7.0 and should not be used in new code. Instead, explode should be used to split a string into an array based on a specified delimiter. Explode is more efficient and versatile than split, making it the preferred choice for string manipulation in PHP.

// Using explode to split a string into an array
$string = "apple,banana,orange";
$array = explode(",", $string);
print_r($array);
