How to generate Random Numbers at Regular Intervals in PHP?
Following is the simple PHP tutorial to demonstrate how to generate random numbers at regular intervals in PHP? I will use jquery setInterval() method for calling PHP file (which generates random numbers) at regular intervals say after every second in my example. I will use PHP rand() function to generate random numbers in PHP. I am using google CDN for jquery libraray. So here is the simple example in PHP to generate random numbers at regular intervals.
index.php file
<!DOCTYPE html>
<html lang="en">
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var auto_refresh_random_numbers = setInterval(
function ()
{
$('#load_random_numbers').load('generate_random_numbers.php').fadeIn("slow");
}, 1000); // refresh random numbers after every 1000 milliseconds
});
</script>
</head>
<body>
<div id="load_random_numbers"> </div>
</body>
</html>
generate_random_numbers.php file
<?php
echo rand();
?>
So, that's all. Above PHP code snippet is very easy to understand by everyone. So, I don't think there is need of any explanation.
