The following script : 
<?php 
$a[0] = 1;
$a[r] = 2;
$a[4] = 3;
$a[c] = three;
$a[d] = one;
$a[a] = two;
?>
Before being sorted
-------------------
<?php 
reset($a);
$b = current($a);
while ($b != "") {
    echo "\$a[" . key($a) . "]=$b\n";
    $b = next($a);
}
asort($a);
?>
After being sorted
-------------------
<?php 
reset($a);
$b = current($a);
while ($b != "") {
    echo "\$a[" . key($a) . "]=$b\n";
    $b = next($a);
}
?>

gives the following output : 
Content-Type: text/html

Before being sorted
-------------------
$a[0]=1
$a[r]=2
$a[4]=3
$a[c]=three
$a[d]=one
$a[a]=two
After being sorted
-------------------
$a[d]=one
$a[c]=three
$a[a]=two
$a[0]=1
$a[r]=2
$a[4]=3

While last week it produced (and so does php3 3.0.12) :

Content-Type: text/html

Before being sorted
-------------------
$a[0]=1
$a[r]=2
$a[4]=3
$a[c]=three
$a[d]=one
$a[a]=two
After being sorted
-------------------
$a[0]=1
$a[r]=2
$a[4]=3
$a[d]=one
$a[c]=three
$a[a]=two
