Sure. Some structures, like an object with member arrays, will have you in a straight-jacket long before you determine where a particular value falls within the structure and how you should construct a reference to it.
Next time, try this:
print('<pre>').print_r($myarray,1).('<pre>'); The results are astonishingly different...
<pre> Array ( [0] => Array ( [0] => Array ( [0] => apple [1] => orange [2] => banana ) [1] => Array ( [0] => apple [1] => orange [2] => banana ) ) [1] => Array ( [0] => apple [1] => orange [2] => banana ) [2] => Array ( [0] => Array ( [0] => apple [1] => orange [2] => banana ) [1] => Array ( [0] => apple [1] => orange [2] => banana ) ) ) </pre>
