What debugging techniques can be used to troubleshoot issues with passing values in form actions in PHP?

When troubleshooting issues with passing values in form actions in PHP, you can start by checking if the form method (GET or POST) matches the method used in the PHP script. Additionally, ensure that the form fields have correct names and that the PHP script is correctly accessing these values using $_POST or $_GET superglobals. You can also use var_dump() or print_r() functions to debug and inspect the values being passed. 

<form method="POST" action="process_form.php">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="Submit">
</form>
```

```php
// process_form.php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];

    echo "Username: " . $username . "<br>";
    echo "Password: " . $password;
}
