How can debugging techniques like printing all POST variables help in troubleshooting PHP scripts?

Printing all POST variables can help in troubleshooting PHP scripts by providing visibility into the data being sent to the server. This can help identify any unexpected or incorrect data being received, which may be causing issues in the script. By printing all POST variables, developers can quickly pinpoint the source of errors and make necessary adjustments to resolve them. 

// Print all POST variables for debugging
foreach ($_POST as $key => $value) {
    echo $key . ' => ' . $value . '<br>';
}
