获取GET方法变量的名称

Question

I have about 5 variables in GET method. They almost always have different names, encoded mostly. How i can get name (not value) of those variables.

example:

$_GET['orchid'] = red;
$_GET['xyc'] = wrack;

and after that, next time i open the page:

$_GET['rose'] = red;
$_GET['gzuy'] = bottle;

Values are not important for now, in this case I need names of variables: "orchid", "xyc" or in second case "rose" and "gzuy".

Answer 1

array_keys($_GET)
