How can a PHP file recognize if it was called from a specific webpage using JavaScript parameters?

To recognize if a PHP file was called from a specific webpage using JavaScript parameters, you can pass a unique identifier or token from the JavaScript code on the webpage to the PHP file. The PHP file can then check for this identifier in the request parameters to determine if it was called from the specific webpage. 

// Check if the specific identifier is present in the request parameters
if(isset($_GET['identifier']) && $_GET['identifier'] == 'unique_token') {
    // Code to execute if called from the specific webpage
    echo "This PHP file was called from the specific webpage using JavaScript parameters.";
} else {
    // Code to execute if not called from the specific webpage
    echo "Access denied.";
}
