How to execute a PHP file in background for every 30 seconds

I am working on flight portal.

If any user book a ticket he/she will get some status like BOOKING SUCCESS / BOOKING PENDING.

If the status is BOOKING SUCCESS the user will get a mail with the ticket details.

In case of BOOKING PENDING a message ( your ticket is in process, you receive a message/email after the ticket confirmed) will be shown to the User.

Now from the backend i have to run a PHP file for every 30 seconds Until i get the status Success.

This will be a continuous process.

Can anyone tell me with a good example.

I will be thankful,

Sowmya

There are multiple ways of doing so.

The best way would be using a using a Cron Job.

Other ways are using a webworker or a an AJAX request, but those require a browser to be active at all times.

Here you can find how to set it up.

As for a webworker, it's an HTML 5 feature so it wouldn't be adviced if you expect people using browsers that don't support it.

If your server runs on cPanel, you can easily set up a cron job. Otherwise you'd have to do it through your terminal I think or through your hosting provider if you have paid hosting without cPanel.

You can set up the cron job like this, the command used in the bar is
/path/to/php -q /absolute/path/to/your/phpfile.php >/dev/null

If you want to just reload your page you can use Javascript to achieve this.

Plain JavaScript

setTimeout(function() {
     window.location.reload();
},  30000);

jQuery

$(function() {
    setTimeout(function() { 
        window.location.reload();
    },  30000);
});

Otherwise, you can use CURL. Visit here to get to know about usage of CURL.

You are looking for CRON, this helps you to schedule your task at your scheduled time. That is your could execute/run your PHP script at the time scheduled by you.

* * * * * /path/to/php_file
* * * * * sleep 15; /path/to/php_file
* * * * * sleep 30; /path/to/php_file
* * * * * sleep 45; /path/to/php_file

The above cron job will run your php script for every 15 seconds. Here sleep will help to delay the script for every 15 seconds.
