How can PHP be used to retrieve mouse click coordinates on an image?

To retrieve mouse click coordinates on an image using PHP, you can utilize JavaScript to capture the click event and send the coordinates to a PHP script via AJAX. The PHP script can then process the coordinates and perform any necessary actions based on the click location. 

```php
<!DOCTYPE html>
<html>
<head>
    <title>Get Mouse Click Coordinates</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
</head>
<body>
    <img src="image.jpg" id="image" style="width: 500px; height: 500px;">
    <script>
        $(document).ready(function(){
            $('#image').click(function(e){
                var posX = $(this).offset().left,
                    posY = $(this).offset().top;
                var clickX = e.pageX - posX,
                    clickY = e.pageY - posY;
                
                $.ajax({
                    type: 'POST',
                    url: 'process_click.php',
                    data: {x: clickX, y: clickY},
                    success: function(response){
                        console.log('Click coordinates sent to PHP script');
                    }
                });
            });
        });
    </script>
</body>
</html>
```

In this code snippet, when the image is clicked, the JavaScript code calculates the click coordinates relative to the image's position on the page. It then sends these coordinates to a PHP script named `process_click.php` via AJAX. The PHP script can access the coordinates in the `$_POST` superglobal and perform any necessary processing.
