Remove duplicates from PHP array

Question

My PHP script is returning some array and I would like to remove duplicates in that array. Can you please tell me how? I dont want to remove duplicates from MySQL, just from PHP

Answer 1

Replace this:

$rows = (object) array('lista' => $rows);
echo json_encode($rows);

With this:

$lista = array_map('unserialize', array_unique(array_map('serialize', $rows)));
echo json_encode((object) array('lista' => $lista));
