"Warning: f() [function.f]: Array was modified by the user comparison function"

[lucavilla]

When I call the results of my price comparison engine I get this error:

"Warning: uksort() [function.uksort]: Array was modified by the user comparison function in /home/myname/public_html/mydomain/calc.php on line 303"

 

The line 303 is this: "uksort($list, $sort);"

I attached the entire calc.php anyway.

 

You can see the error in action here: http://alturl.com/dgku

 

The error appeared about 1 month ago with no apparent reason. I didn't get it before.

 

What can be the problem?
