run php file when browser is closed

Question

i am having a php file that is saving data into database, i want the file to keep on running even if the browser is closed. this is what i tried: js.php file:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>   
<script type="text/javascript">

  setInterval(function() {
    $.get('http://localhost/cryptopiamodelp/tst.php/', function(data) {
      //do something with the data
      alert('Load was performed.');
    });
}, 5000);
</script>

tst.php file:

<?php

$con = mysqli_connect('localhost','root','','cryptopiamodel') or die(mysql_error());
$sqli = "INSERT INTO test VALUES ('')" or die(mysqli_error());
mysqli_query($con,$sqli) or die(mysqli_error($con));
?>

but this only works when the browser is opened, is this possible in php to execute js.php file when the browser is closed so that the data is saved into database continuously? Thanks in advance.

You need to use a [**CRON**](https://stackoverflow.com/questions/18737407/how-to-create-cron-job-using-php) — Hamza Abdaoui, Mar 14 '18 at 15:39
Considering this is running on `http://localhost` what do we think the odds are that it's running on a *nix style system that has Cron? — CD001, Mar 14 '18 at 15:41

You can set up a cron job. A cron job allows you to setup almost any kind of schedule.Depending on where you are hosting your web application a cron job can be set differently.

For example if your site hosting comes with a cPanel, they have an option to define a cron job. You can set up a schedule and give path to your php file.

This does not answer the question at all. – catbadger Mar 14 '18 at 15:41
He needs a way to keep running a file even when the browser is closed. Is CRON not the right way to do that ? – abhinav pandey Mar 14 '18 at 15:42
@abhinavpandey - irrespective as to whether Cron is the *right* answer or not... your answer is basically a link to an external resource; you *should* at least provide a brief example of how to set up a Cron job in your answer - or possibly Task Scheduler. – CD001 Mar 14 '18 at 15:44
Agreed. Let me modify that, – abhinav pandey Mar 14 '18 at 15:53

You can use ignore_user_abort to avoid php hanging the execution upon browser disconnection.

Then, you can use set_time_limit to change the default time limit (30 sec) to no limit or any other value that you need:

ignore_user_abort(true);
set_time_limit(0);

Read http://php.net/manual/en/function.ignore-user-abort.php
