Question

I have the following array:

$array = array(1=>'one', 2=>'two', 3=>'three');

I know it’s possible to use array_search(); to return “1” when searching for “one”, but how do I return “one” when searching for “1”?

I’ve tried $array[1], but this does not work. I’m guessing that’s because the array has => in each value, as it normally works without that.

EDIT: Sorry, it was my variable scope.

PHP’s arrays are used to point from keys to values. In your case 1 is a key and "one" is a value. You need to use array_search when you’re trying to get a key from a value, but you’re just using an array normally so you can just do:

$array[1]
