What are the limitations of PHP in recognizing frames or iFrames?

PHP does not have built-in support for recognizing frames or iFrames as they are handled by the browser. To work around this limitation, you can use client-side JavaScript to detect frames or iFrames and then pass that information to your PHP script using AJAX or form submission. 

// PHP code snippet to handle information passed from client-side JavaScript
if(isset($_POST['isFrame'])) {
    $isFrame = $_POST['isFrame'];
    
    if($isFrame) {
        echo "This content is being displayed in a frame or iFrame.";
    } else {
        echo "This content is not being displayed in a frame or iFrame.";
    }
}
