Is it a best practice to avoid using $_POST arrays directly within functions in PHP?

It is generally considered a best practice to avoid using $_POST arrays directly within functions in PHP to improve code readability, maintainability, and reusability. Instead, it is recommended to pass the necessary data as function parameters to make the function more self-contained and easier to test. 

// Avoid using $_POST arrays directly within functions
function processFormData() {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data
}

// Instead, pass the necessary data as function parameters
function processFormData($name, $email) {
    // Process the form data
}

// Call the function with the required data
$name = $_POST['name'];
$email = $_POST['email'];
processFormData($name, $email);
