How do I run PHP code every 1 minute?

Question

I have got this php code

$uploaded=0;
$_SESSION['numberOfUploadsInTimeFrame']=$uploaded;
if (isset($_POST['UploadMSub'])) {
    $uploaded++;
    $_SESSION['firstUploadTime'] = time();
}


function isFileUploadAllowed() {
    $isAllowed                  = true;
    $timeNow                    = time();
    $timeFrameInSeconds         = 30;
    $maxUploadsInTimeFrame      = 5;
    $firstUploadTime            = $_SESSION['firstUploadTime'] ? intval($_SESSION['firstUploadTime']) : $timeNow;
    $numberOfUploadsInTimeFrame = $_SESSION['numberOfUploadsInTimeFrame'] ? intval($_SESSION['numberOfUploadsInTimeFrame']) : 0;
    $givenTimeFrameExpired      = (($firstUploadTime + $timeFrameInSeconds) < $timeNow);
    if (!$givenTimeFrameExpired) {
        if ($numberOfUploadsInTimeFrame + 1 > $maxUploadsInTimeFrame) {
            $isAllowed = false;
        }
    }

    if ($isAllowed === true) {
        if ($givenTimeFrameExpired) {
            $_SESSION['firstUploadTime'] = $timeNow;
            $_SESSION['numberOfUploadsInTimeFrame'] = 0;
        }

        $_SESSION['numberOfUploadsInTimeFrame']++;
    }
    return $isAllowed;
}

How can i make that so every 60 seconds $_SESSION['numberOfUploadsInTimeFrame'] will be decreased by one Please do not suggest sleep() or Cron

You can store all upload times than count the ones that are inside your timeframe. — Roland Starke, May 27 '16 at 17:49
If you want to run from your browser you would use a [meta-refresh](https://en.wikipedia.org/wiki/Meta_refresh) — Jay Blanchard, May 27 '16 at 17:54
There is no need to run your script each min. You could just calculate the time difference between 2 calls. — Roland Starke, May 27 '16 at 17:55
Well it will calculate the difference only once,won't it?@RolandStarke — Tom Odell, May 27 '16 at 17:57
@JayBlanchard actually i think kamal pal's suggestions was the easiest now i am trying to do that — Tom Odell, May 27 '16 at 17:57

I have tried that and it is not working @AniMenon please delete that — Tom Odell, May 27 '16 at 18:17
@TomOdell There are multiple solutions given in those links like cronjob, setinterval, while-loop, etc. — Ani Menon, May 27 '16 at 18:26
@AniMenon there 2 solutions and none of them was accepted by asker and none is satisfying for me — Tom Odell, May 27 '16 at 18:28

You can use jQuery's ajax method, inside setInterval of 60000 ms = 1 min , see example below:

setInterval(function() {
    $.ajax({
        url: 'url to your php script you want to execute',
        method: 'post',
        aysnc: false,
        data: {
            var: 'value'
        }
        success: function(response) {
            console.log(response);
        }
    });
}, 60000);

What about php?What should i write there? – Tom Odell May 27 '16 at 18:22
you can write php script, which you want to execute every min – kamal pal May 27 '16 at 18:23
But how do i check if this request was sent?There is not "data" here – Tom Odell May 27 '16 at 18:25
you can check on browser console, it will output what it receives from php script, additionally you can write logs in your php script to debug process. – kamal pal May 27 '16 at 18:27
I mean how php script will know if this request was sent – Tom Odell May 27 '16 at 18:28
you have to provide url to your php script, in ajax call .. it will be executed, see I've left placeholder for url in example – kamal pal May 27 '16 at 18:31
I know but should i just posts $_SESSION['numberOfUploadsInTimeFrame']-- without any ifs? – Tom Odell May 27 '16 at 18:32
you don't need to post session, php script can access that, but if you want to send any additional data, you can send it .. see my updated answer – kamal pal May 27 '16 at 18:35
