How can PHP developers handle situations where cookies are being blocked by the client, potentially affecting variable transmission to functions?

When cookies are being blocked by the client, PHP developers can use alternative methods to transmit variables to functions, such as using sessions or passing variables through GET or POST requests. This ensures that the functionality of the application is not affected by the client's cookie settings. 

// Example of passing variables through GET request
if(isset($_GET['variable'])) {
    $variable = $_GET['variable'];
    // Call function with the variable
    functionName($variable);
}

// Example of using sessions
session_start();
if(isset($_SESSION['variable'])) {
    $variable = $_SESSION['variable'];
    // Call function with the variable
    functionName($variable);
}
