How to get the first item from an associative PHP array?

If I had an array like:

$array['foo'] = 400;
$array['bar'] = 'xyz';

And I wanted to get the first item out of that array without knowing the key for it, how would I do that? Is there a function for this?

Answer

reset() gives you the first value of the array if you have an element inside the array:

$value = reset($array);

It also gives you FALSE in case the array is empty.
