How to Retrieve a Client's Timezone in PHP?

Retrieving Client Timezone in PHP

How can you determine the timezone used by a website visitor?

To address this issue, a PHP-based solution leverages jQuery and PHP. Implement the following steps:

  1. PHP Code Integration:
<code class="php">session_start();
$timezone = $_SESSION['time'];</code>
  1. jQuery Script in Header:
<code class="html"><script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script></code>
  1. Client Timezone JavaScript:
<code class="javascript">$(document).ready(function() {
    if ("<?php echo $timezone; ?>".length == 0) {
        var visitortime = new Date();
        var visitortimezone = "GMT " + -visitortime.getTimezoneOffset() / 60;
        $.ajax({
            type: "GET",
            url: "http://domain.com/timezone.php",
            data: 'time=' + visitortimezone,
            success: function() {
                location.reload();
            }
        });
    }
});</code>
  1. Timezone.php Content:

Create a file named timezone.php with the following code:

<code class="php"><?php
session_start();
$_SESSION['time'] = $_GET['time'];</code>
  1. Mechanism Explanation:

This solution utilizes jQuery to determine the client's local time and store it as a PHP session variable. The timezone.php is a small PHP script called via AJAX to save the client's timezone offset into the PHP session.

  1. Retrieve Client Timezone:

Once the page reloads, you can access the $timezone variable in PHP to obtain the visitor's timezone offset.
