How can debugging tools like Firebug be used to troubleshoot issues with PHP scripts that are not producing the expected output?

If a PHP script is not producing the expected output, debugging tools like Firebug can be used to inspect the network requests and responses to identify any errors or issues. By using Firebug's console feature, developers can view any errors or warnings that may be occurring in the PHP script. Additionally, developers can use Firebug's network tab to check the response data from the server and ensure that the PHP script is functioning correctly. 

<?php
// Example PHP script with debugging using Firebug
$data = array(1, 2, 3, 4, 5);

// Output the data for debugging
echo "<pre>";
print_r($data);
echo "</pre>";
?>
