How can PHP developers effectively troubleshoot issues related to form data transmission?

To effectively troubleshoot issues related to form data transmission in PHP, developers can start by checking the form method (POST or GET) and ensuring that the form action attribute points to the correct PHP file. They can also use var_dump($_POST) or var_dump($_GET) to inspect the data being transmitted and check for any errors or missing values. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    var_dump($_POST);
    // Check and process form data here
}
?>
