What is the recommended method to pass variables to functions in PHP to avoid potential pitfalls like multiple page reloads?

When passing variables to functions in PHP to avoid potential pitfalls like multiple page reloads, it is recommended to use POST or GET methods to send data securely between pages. This can help prevent unintended data modifications or repeated form submissions. Additionally, using sessions or cookies can also be helpful for storing and accessing variables across multiple pages.

// Using POST method to pass variables to a function
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $variable = $_POST['variable'];
    myFunction($variable);
}

function myFunction($variable) {
    // Function logic here
}
