Loop page

 <?php
     $a = 1;
     while (true) {
         echo $a;
         $a++;
         sleep(1);
     }

You can do this using output buffering.

$a = 1;
while(true){
    ob_start();
    echo $a;
    $a++;
    ob_flush();
    sleep(1);
}

You will need to configure php to allow for this if you have not done so already. There are settings in the PHP ini for it. This answer will explain how to do this PHP echo-ing content as page loads

It is worth noting that the code above will cause a php timeout based on whatever you have set in the php.ini
