associative array: how to acess 1st and next element at the same time

[phpforum]

I have this associative array:

$products=array('chair'=>100, 'sofa'=>200, 'bed'=>300);

I need to sort this products array on basis of description i.e chair , sofa etc.

I would be writing a function compare to sort this:

compare($x, $y)

{

if $x==$y
{
.....
}
elseif $x > $y
{
......
}

else
......

here $x is teh first element of the product array i.e chair=>100 and $y is the second element
of product i.e sofa=>200... But i am trying to find out how can i access the first and second element of this associative array to pass to this compare function. With a normal numerical array i could have done ..$products[0], $products[1]...but i cannot figure this out.

Any help would be appeciated.. Thanx in advance.

pppppp's suggestion is probably the best for you, but for more unusual sorting rules you would pass the array elements to your compare function through uksort().
