The $index argument seems to be NULL for append operations, e.g.:<?php// example extension classclass Test extends ArrayIterator{    public function offsetSet($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')
