    The $index argument seems to be NULL for append operations, e.g.:

    <?php

    // example extension class
    class Test extends ArrayIterator
    {
    public function     offsetSet($index, $newval)
    {
    echo     'Test::offsetSet('.var_export($index, true).', '.var_export($newval, true).")\n";
    }
    }

    // test
    $i = new Test;
    $i[] = 'append a value';

    ?>

    The result is:

    Test::offsetSet(NULL, 'append a value')
