// Get the values of input fields from a HTML form if ($_SERVER['REQUEST_METHOD'] == 'POST') { $username = $_REQUEST['username']; $password = $_REQUEST['password']; // Do something with the input data }
// Get the value of a URL parameter if (isset($_GET['page'])) { $page = $_GET['page']; // Display the contents of the requested page }This example shows how to retrieve the value of the "page" parameter from a URL using $_GET. This can be useful for creating dynamic web pages with different content depending on the requested URL. The getRequest getArgs() function is a built-in feature of PHP, so it is not part of a package or library.
