Apache_Solr_Document should support toArray() or similar functionality.

[ant92083]

I have noticed that the library supports retrieving the values of the
fields or the keys of the fields but not both together. I find myself
extending Apache_Solr_Document for such a trivial task. Could we not
add something to Apache_Solr_Document such as:

public function toArray() {
return $this->_fields;
}

I thought about this long and hard and it makes sense because if you
work in a sort of framework such as Zend having a the key/value pairs
is vital to doing some pretty mundane tasks when working with the
table/gateway access patterns. Thoughts suggestions?

Apace_Solr_Document is iterable just like an associative array, which i imagine is what you're looking to do.

<code>
// this works, and is the typical use case
foreach ($document as $key => $value) {...}
</code>

The key and field methods are just analogies to array_keys and array_values since they're not covered by the IteratorAggregate interface. You could also work directly with the iterator if you so desire.

This is correct. I forgot that it was an interface that was implemented.  This suits my needs perfectly.
