bubble sort problem

[Anon]

I want to apply bubble sort on array like this

$arr=array("chris" => 105, "Alfred" => 98 , "Patrick" => 110);

How can I implement bubble sort. How I can sort on keys ? How I can sort on values ?

How I can identify this -> $arr[$j+1} > $arr[$j] on the above array while implementing bubble sort on the above array ?

try defining your array as:
$arr=array (105=>"Chris", 98=>"Alfred",

Why don't you use the asort() & ksort() functions?
