$winter = array("December", "January", "February");
$spring = array("March", "April", "May");
$summer = array("June", "July", "August");
$fall = array("September", "October", "November");
$seasons = array("Winter" => $winter, "Spring" => $spring, "Summer" => $summer, "Fall" => $fall);
How would I access "March" using the $seasons array?
