How To Use setInterval in PHP?

Question

I want to ask that how can i use php function again and again after some time automatically just like setInterval in Javascript. We set the time and it is on its job until t

Answer 1

Unlike Javascript, PHP is executed on the server side. There is no setTimeout functionality in PHP. You can get close by using cronjobs - or other PHP scripts - that call your scripts though.

Answer 2

I would suggest using setInterval to poll for results from a .php page using AJAx and then output your results.

So it would look something like this using jQuery:

<script>
    var poll = true;
    var getData = function() {
        if (poll) {
            $.get('getData.php', function(data) { $('#likes').html(data); });
        }
    };

    $(document).ready(function() {
        setInterval(getData, 5000);
        $('.comm').click(function() { poll = false; });
        $('.comm').blur(function() { poll = true; });
    });
</script>
