Answer 1

$array = array(
            'alevel1key1' => array(
                                'alevel2key1' => 'alevel2value1', 
                                'alevel2key2' => array(
                                                     'alevel3key1' => 'alevel3value1',
                                                     'alevel3key2' => 'alevel3value2',
                                                 ),
                             ),
            'blevel1key2' => array(
                               'blevel2key1' => 'blevel2value1'
                             ),
          );

1) Now if you want to access the value of lets say key alevel3key2, then you might have done:

$array['alevel1key1']['alevel2key2']['alevel3key2'];

2) Now assuming the above array to be objects, then you might have done:

$array->alevel1key1->alevel2key2->alevel3key2;
