PHP sorting arrays numerically by key value descending [duplicate]

This question already has answers here: Sort array by numeric keys (4 answers) 开发者_开发知识库 Closed last month.

Is there an option in PHP to sort an array by key value descending?

I am aware that you can sort key values with ksort

Yes, the krsort

$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
krsort($fruits);

I believe krsort() is what you're looking for.
