usort() does not seem to be actually sorting the
array.  The user-defined sort function is being
called, but no matter what the function does, the
array remains in its original order.

The "Example 1" cut-and-pasted from the usort()
function documentation page:

   function cmp ($a, $b) {
       if ($a == $b) return 0;
       return ($a > $b) ? -1 : 1;
   }

   $a = array (3, 2, 5, 6, 1);

   usort ($a, "cmp");

   while (list ($key, $value) = each ($a)) {
       echo "$key: $value\n";
   }

Produces the following output:
   0: 3
   1: 2
   2: 5
   3: 6
   4: 1

(Should have returned the values in descending
order, as on the usort() documentation page.)

The other examples do not work on this platform,
either; they always leave the array unmodified.

Configuration line reported by phpinfo():
'./configure' '--with-apache=../apache_1.3.26' '--with-gd=/

Works fine with me with PHP 4.2.3RC2. Seems to be a duplicate of Bug #17449.

[2002-09-06 05:32 UTC] sniper@php.net

Closed then. Get the 4.2.3 when it's released..today/tomorrow iirc..
