How can the AdoDb engine be used to display all SQL queries in a PHP script?

To display all SQL queries in a PHP script using the AdoDb engine, you can enable query logging in AdoDb. This will allow you to see all the SQL queries being executed by your script. By setting the `debug` property to true, you can see all the queries in the output.

<?php

// Include the AdoDb library
require_once('path/to/adodb/adodb.inc.php');

// Create a new AdoDb connection
$conn = ADONewConnection('mysqli');

// Set the debug mode to true to enable query logging
$conn->debug = true;

// Connect to the database
$conn->Connect('hostname', 'username', 'password', 'database_name');

// Perform your SQL queries here

// Close the connection
$conn->Close();

?>
