How can PHP developers effectively debug form submission issues, as suggested in the forum responses?

To effectively debug form submission issues in PHP, developers can start by checking the form's action attribute to ensure it points to the correct PHP file handling the form submission. They should also inspect the $_POST array to see if form data is being properly submitted. Additionally, using functions like var_dump() or print_r() can help display the form data for debugging purposes. 

<form method="post" action="submit_form.php">
    <input type="text" name="username">
    <input type="password" name="password">
    <button type="submit">Submit</button>
</form>
```

```php
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    echo "Username: " . $username . "<br>";
    echo "Password: " . $password;
}
?>
