How can PHP be used in conjunction with JavaScript to accurately determine the displayed image size?

To accurately determine the displayed image size using PHP in conjunction with JavaScript, you can use JavaScript to get the dimensions of the image element on the client-side and then pass this information to PHP using AJAX. PHP can then process this information and return the image size back to JavaScript for further use. 

<?php
// PHP script to receive image dimensions from JavaScript
if(isset($_POST['width']) && isset($_POST['height'])){
    $width = $_POST['width'];
    $height = $_POST['height'];
    
    // Process the image dimensions
    // For example, you can store them in a database or perform any other operation
    // Return the processed data if needed
    echo "Image dimensions received: Width - $width, Height - $height";
}
?>
