I have a PHP array with some predefined values:

$aArray = array(
    0 => 'value0',
    1 => 'value1'
);

I need to create a function where the string input will always return the same, valid, array key so that when I call:

GiveMeAKey('http://www.google.com');  // May return 0 or 1

I receive always the same key (I don't care which one) from the array. Obvisously I can't store the relationship in a database and the string passed to the GiveMeAKey method can be any URL.

I wonder if there is a way of doing that ?
