public MongoCursor::count ([ bool $foundOnly = FALSE ] ) : int

This method does not affect the state of the cursor: if you haven't queried yet, you can still apply limits, skips, etc. If you have started iterating through results, it will not move the current position of the cursor. If you have exhausted the cursor, it will not reset it.
