How can PHP's explode function be used to separate data elements in a string?

To separate data elements in a string using PHP's explode function, you need to specify the delimiter that separates the elements. The explode function takes in two parameters: the delimiter and the string to be split. It then returns an array containing the individual elements.

$data = "apple,banana,orange,grape";
$elements = explode(",", $data);

foreach ($elements as $element) {
    echo $element . "<br>";
}
