How can the order of script execution impact the functionality of a PHP form handling script?

The order of script execution can impact the functionality of a PHP form handling script if the form processing code is placed before the form submission check. To solve this issue, ensure that the form submission check is done before processing the form data in order to prevent errors or unexpected behavior. 

// Check if the form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    // Your form handling code here
}
