// connect to a database $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'myusername', 'mypassword'); // enable query logging $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); $pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC); $pdo->exec("SET NAMES utf8mb4"); // run some queries $stmt = $pdo->query("SELECT * FROM users"); $stmt = $pdo->query("SELECT * FROM products"); // retrieve the query log $queryLog = $pdo->getQueryLog();In this example, we connect to a MySQL database using PDO and enable query logging by setting some attributes. We then execute two queries and retrieve the query log using the getQueryLog method. It is difficult to determine the package library without more context or information about the code. However, it is likely that this code is part of a larger PHP application or framework that uses PDO to interact with a database.
