// First, connect to the database $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password'); // Run the query to find the user by email $stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email'); $stmt->execute(['email' => 'firstname.lastname@example.org']); // Fetch the user record from the database $user = $stmt->fetch(PDO::FETCH_ASSOC); // Output the user's details echo 'Name: ' . $user['name'] . 'In this example, we connect to a database using the PDO library in PHP. We then prepare a query to search for a user by their email address, and execute the query with the email parameter set to `"email@example.com"`. We then fetch the resulting user record from the database and output their details. The package library for this function would depend on the specific database library being used. In this example, we are using the PDO library to connect to a MySQL database, so the package library would be `pdo_mysql`.
