How to use setInterval and clearInterval jQuery methods in PHP?

I will explain usage of setInterval and clearInterval jQuery methods with the help of simple example in PHP. Suppose there is a PHP array in which there are 3 elements. I want to display all of them one by one at regular intervals and stop when all the three array elements have been displayed. I will use setInterval and clearInterval jQuery methods here to implement it.

Here is my index.php file

Here is my myphpfile.php file

$questions=array(

                 "Array Item 0",

                 "Array Item 1",

                 "Array Item 2");

if (isset($_REQUEST["count"])) 

{

    echo $questions[intval($_REQUEST["count"])];

}

?>
