    I experimented what happens when arrays are inserted:

    <?php
    $heap     = new SplMinHeap();
    $heap->insert([22,333]);
    $heap->insert([2,33]);
    $heap->insert([222,3]);

    var_export($heap->extract());
    echo     '<br>';
    var_export($heap->extract());
    echo     '<br>';
    var_export($heap->extract());
    ?>

    Output:

    array ( 0 => 2, 1 => 33, )
    array ( 0 => 22, 1 => 333, )
    array ( 0 => 222, 1 => 3, )
