alternatively you can define the key yourself like this:

$yearArray = array("year1" => "1994", "year2" => "1995", "year3" => "1996", "year4" => "1997", "year5" => "1998", "year6" => "1999", "year7" => "2000", "year8" => "2001", "year9" => "2002", "year10" => "2003", "year11" => "2004", "year12" => "2005", "year13" => "2006", "year14" => "2007", "year15" => "2008", "year16" => "2009");

so that you know exactly which element has which year, you can change the keys accordingly i did the above only as an example as an alternative solution.

To access year 2000:
echo $yearArray["year7"];

it all depends what you want to use the array for essentially, both methods have very different uses.
