Table listing of months

I have the following snippet of code: <?php // contents of $monthlyarchivereverse is generated by a different // piece within a content managent system. The data, or format // can not be changed. $monthlyarchivereverse = array("/08/index.html August 2003",

                                "/07/index.html July 2003",
                                "/06/index.html June 2003",
                                "/05/index.html May 2003"
                               );

$monthlyarchive = array_reverse($monthlyarchivereverse); function lightdark($rest) { if ($rest%2) {

     $color = "#eee";

} else {

     $color = "#fff";

} return $color; } foreach ($monthlyarchive as $string) { list($link, $month, $year) = split(" ",$string); $shortmonth = substr($month,0,3); $a[$year][] = "<a href=\"$link\">$shortmonth</a>"; } reset($a); $array_first_key = key($a); while (count($a[$array_first_key]) < 12) { array_unshift($a[$array_first_key], " "); } foreach ($a as $year=>$list_of_strings) { echo "<table class=\"mcalendar\">\n"; echo " <tr><th colspan=\"4\" class=\"mcalendar\">$year</th></tr>\n <tr>\n"; foreach ($list_of_strings as $key=>$date_string) {

     if($key%4 || $key==0) {
       } else {
     echo " </tr>\n <tr>\n";

} echo " <td class=\"mcalendar\" style=\"background-color : ".lightdark($key).";\">".rtrim($date_string)."</td>\n"; } echo " </tr>\n</table>\n"; } ?> Which when run, will generate a table that looks like this, with each month hyperlinked to its respective link from the array: +-----------------------+

   |     |     |     |     |

+-----------------------+

   |     |     |     |     |

+-----------------------+ | May | Jun | Jul | Aug | +-----------------------+ I now want to change this, to something like this: +-----------------------+ | Jan | Feb | Mar | Apr | +-----------------------+ | May | Jun | Jul | Aug | +-----------------------+ | Sep | Oct | Nov | Dec | +-----------------------+ ...where only those months that have an associated hyperlink will be linked, and the others will just be displayed without a link. How can I achieve this?
