How can the debugging process be improved when encountering issues with form data submission and retrieval in PHP scripts?

When encountering issues with form data submission and retrieval in PHP scripts, it is important to check for errors in the form's method attribute, input names, and the PHP script that processes the form data. Additionally, using debugging tools like var_dump() or print_r() can help identify any issues with the submitted data. 

<?php
// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Retrieve form data
    $username = $_POST['username'];
    $password = $_POST['password'];

    // Process the form data
    // Add your processing logic here

    // Debugging output
    var_dump($username);
    var_dump($password);
}
?>

<form method="post" action="">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="Submit">
</form>
