$myCollection = $con->Database_name->Collection1;

$ops = array(
        array(
            "$lookup" => array(
            "from" => "Collection2",
            "localField" => "Collection1.field",
            "foreignField" => "Collection2.field",
            "as" => "Name of Alias"
        )
    )
    );

$results = $myCollection->aggregate($ops);

var_dump($results);
