How to check mail open or not using php script

To check if an email has been opened or not using a PHP script, you'll need to use a combination of techniques. Here's a step-by-step guide:

Method 1: Using a tracking pixel

Create a small image (e.g., a 1x1 pixel GIF) and store it on your server.
In your email template, add a link to this image. This link will be used to track whether the email has been opened.
When the email is opened, the image will be loaded, and you can track this event using PHP.

Here's some sample PHP code to get you started:

<?php
// Assume you have a variable $email_id containing the email ID
// and a variable $tracking_pixel_url containing the URL of the tracking pixel

// Check if the email has been opened
if (isset($_GET['email_opened'])) {
    // Update your database to mark the email as opened
    //...
} else {
    // Check if the tracking pixel has been loaded
    if (isset($_GET['tracking_pixel'])) {
        // Update your database to mark the email as opened
        //...
    }
}
?>

Method 2: Using a third-party service

Integrate a third-party email tracking service (e.g., Mailgun, Sendgrid, or Sanebox) into your PHP script.
These services provide APIs to track email opens, clicks, and other events.
When an email is opened, the service will send a request to your PHP script, allowing you to update your database accordingly.

Here's some sample PHP code using Mailgun's API:

<?php
// Assume you have a variable $email_id containing the email ID
// and a variable $mailgun_api_key containing your Mailgun API key

// Check if the email has been opened
if (isset($_GET['mg_event']) && $_GET['mg_event'] == 'open') {
    // Update your database to mark the email as opened
    //...
}
?>

Method 3: Using a custom solution

Create a custom solution using JavaScript and PHP.
Add a JavaScript code to your email template that sends a request to your PHP script when the email is opened.
In your PHP script, update your database to mark the email as opened.

Here's some sample PHP code using JavaScript and PHP:

<?php
// Assume you have a variable $email_id containing the email ID

// Check if the email has been opened
if (isset($_POST['email_opened'])) {
    // Update your database to mark the email as opened
    //...
}
?>

JavaScript code (in your email template):

<script>
    function trackEmailOpen() {
        var xhr = new XMLHttpRequest();
        xhr.open('POST', 'your-php-script.php', true);
        xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
        xhr.send('email_opened=1');
    }
</script>

Remember to adjust the code according to your specific requirements and the service you're using. Additionally, ensure that your email service provider allows tracking pixels or custom solutions.
