// Initialize database connection $db = new mysqli('localhost', 'username', 'password', 'database_name'); // Define the find_by_name function to query the database function find_by_name($name) { global $db; $query = "SELECT * FROM users WHERE name = '$name'"; $result = $db->query($query); return $result->fetch_assoc(); } // Example usage of the find_by_name function $user = find_by_name('John Smith'); echo "Username: " . $user['username']; echo "Email: " . $user['email'];This example assumes that the "users" table in the database has columns for "name", "username", and "email". The function takes a name as an argument and returns a single row as an associative array, which can then be used to display the user's information. The package library that contains the "find_by_name" method in PHP will depend on the specific framework or library being used. However, most PHP frameworks such as Laravel, CodeIgniter, and Yii have built-in database query builders or ORM (Object Relational Mapping) that offer similar functionality to the "find_by_name" method.
