[thelist] PHP String Indexed Arrays

[Jacob Aust]

Matt,

I tried this:

----------------------------------
function print_sections() {
    global $sections;
    global $myhref;
    echo"<p class=\"subWORK\">";
    foreach ($sections as $sectionID => $section) {
        echo"<a href=\"$myhref?$sectionID\"> $section </a>";
        if ( !($section == end($sections)) )
        {
            echo"//";
        }
        else
        {
            //currently on last item
        }
    }


}

-----------------------------------------

And it gave me this:


Case studies // by type by type by type by type by type by type by type by
type by type by type by type by type by type by type by type by type by type
by type by type by type by type by type....

Infinite loop.

I think it has to do with the fact that the end() funcion sets the array
pointer to the last element, which is great for the test, but messes with
the foreach() loop.

Ahhhh.....still stumped.

Thanks for the help anyway.
