Question

I have an array with series of objects and I want to search through the objects to compare and remove duplicates. An example of the structure is:

Array
(
    [0] => stdClass Object
        (
            [lrid] => 386755343029
            [uu] => website.address.com
        )

    [1] => stdClass Object
        (
            [lrid] => 386755342953
            [uu] => website.address.com
        )
)

With the UU key being a website address and I only want to show the first version rather than the duplicate. Any help would be greatly appreciated.

Answer 1

$sites = array();
foreach ($array as $object) {
  if (!array_key_exists($object->uu, $sites)) {
    $sites[$object->uu] = $object;
  }
}

If you want a “normal array”, use array_values() with $sites as argument.
