How can PHP developers ensure proper separation and handling of GET and POST variables to prevent conflicts and errors?

To ensure proper separation and handling of GET and POST variables in PHP, developers can use conditional statements to check the request method and process the variables accordingly. By checking if the request method is GET or POST, developers can prevent conflicts and errors that may arise from mixing up the variables. 

if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    // Handle GET variables
    $variable = $_GET['variable'];
} elseif ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Handle POST variables
    $variable = $_POST['variable'];
}
