How does using the $_REQUEST superglobal array affect the usage of GET and POST methods in PHP?

Using the $_REQUEST superglobal array in PHP allows you to access both GET and POST parameters in a single array. This can be convenient, but it can also lead to security risks if not handled properly. It's recommended to use specific superglobal arrays like $_GET and $_POST when dealing with form submissions to ensure data integrity and prevent potential vulnerabilities. 

// Using specific superglobal arrays ($_GET and $_POST) instead of $_REQUEST
if(isset($_GET['username'])){
    $username = $_GET['username'];
}

if(isset($_POST['password'])){
    $password = $_POST['password'];
}
