I haven't seen the rest of this thread so this may be irrelevant ... but

foreach($array as $key=>$value)
{       $array[$key] = "fred";

... alters an array while traversing it. Your case seems more complicated
but I would have thought nesting foreaches in this way would allow you to
access the original element.

foreach($array as $key1=>$value1)
{       foreach($array as $key2=>$value2)
{       $array[$key1][$key2] = "fred";

        Good day,

        Thanks to all who replied.

        This isn't quite what I needed, though.  I _have_ the array (or
        list would do, too).  What I need to do is _CREATE_ the array
        $myarray['foo']['bar']['green']['apple'] and set it to some value.
        traversing said array isn't hard, as you pointed out.

        foreach() doesn't work, as it just uses a copy of the original
array.  I
        think there might be some way to use variable references, but I
        gotten one to work yet.

        Any other suggestions?

        I did something like this recently. Here's how I did it:

        $some_value1 = 'Hello World';
        $myarray['foo']['bar']['green']['apple'] = $some_value1;

        function get_opt($arr, $keys,$sep=':') {
            $var = $arr;
            $tmp = split($sep,$keys);
            foreach ($tmp as $k => $v) {
                $var = $var[$v];
            if (isset($var)) return $var;
            return '';

        echo get_opt($myarray, 'foo:bar:green:apple');

        It needs refining, but it should do the job. That's entirely from 
        memory, mind you.. it should work, though.
