$result = $wpdb->get_results( "SELECT * FROM wp_posts" );
$results = $conn->get_results("SELECT id, name, age FROM employees");This code gets the id, name, and age columns from the employees table in the database. The $conn variable could suggest that this belongs to a custom package library. In summary, the get_results function in PHP is a useful database-related feature used to retrieve multiple rows of data. Its purpose is to query a database and obtain a set of results. The package library can vary, depending on the PHP framework or custom package used in the code.
