+/* Prototype: array array_change_key_case ( array $input [, int $case] )
+ Description: Changes the keys in the input array to be all lowercase
+ or uppercase. The change depends on the last optional case parameter.
+ You can pass two constants there, CASE_UPPER and CASE_LOWER(default).
+ The function will leave number indices as is.
