I want to include a search by D.O.B with these fields "birth_day", "birth_month"
function search_users($term, $limit = 10, $friends = false) {
$sql = "SELECT * FROM `users` WHERE
(username LIKE '%{$term}%' OR first_name LIKE '%{$term}%' OR last_name LIKE '%{$term}%' OR email_address LIKE '%{$term}%') AND bannned='0'
";
