array to variable

[Anon]

Hello,
when I try to change an array
like $abc[a] = apple, $abc = banana,
I write
while(list($a, $b, $c, $d)=each($abc)){
${$c} = $d;
}

What I expect is
$a = apple and $b = banana

Please advise.

<?
$abc['a'] = 'apple';
$abc['b'] = 'banana';

 while(list($key, $value) = each($abc))
 {
       //$key will hold the array index,
       //while $value holds the content
       echo "$key = $value\n<BR>";

       //you can do something else here
       //besides a mere output
 }

?>

Output:
a = apple
b = banana
