WordPress and Mysql connection

WordPress has ton a lot of cool things to simplify the life of a developer. One of those things is to facilitate the whole mysql connection.

so, to begin usage, we set the variable as global:

global $wpdb;

once we initialize as WP likes it, then we can use it:

$queries = $wpdb->get_results("SELECT * FROM test");

foreach ($queries as $query)
{
echo $query->field;
}
