What are the potential drawbacks of using PHP to redirect form submissions to achieve a specific URL format?

Potential drawbacks of using PHP to redirect form submissions to achieve a specific URL format include increased server load, slower page load times, and potential security vulnerabilities if not implemented correctly. To address these issues, consider using client-side JavaScript to manipulate the form submission URL before sending the data to the server. 

// Sample PHP code to handle form submission and redirect to a specific URL format
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    // Redirect to specific URL format
    $redirect_url = "https://example.com/" . $_POST['username'];
    header("Location: $redirect_url");
    exit;
}
