Operating System: internet site
PHP Version: 4.3.2RC2
New Comment:
This is actually referring to a situation as shown in example #3 at
php.net/list You are not using an array, you are using plain
variables, so don't need to worry about it...
Not sure how this can be rewritten, how do you think this can be
solved? All the examples demonstrate that your code in this report is
wrong.

> To me, that says that each will issue an array with the element [0]
containing the key of an array postion, and the element[1] containing
the value of an
> array position.

key to the

the right.
