How does the order of code execution impact PHP form processing?

The order of code execution in PHP form processing is crucial because certain operations, such as validating form data or processing form submissions, need to occur in a specific sequence to ensure the form functions correctly. To address this issue, it is important to structure your PHP code in a way that follows the logical flow of form processing steps, such as first checking if the form has been submitted, then validating the form data, and finally processing the form data. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Validate form data
    $name = $_POST["name"];
    $email = $_POST["email"];
    
    // Process form data
    // Insert code here to process the form data
}
?>
