Variable array names

<pre>
I'm unable to echo the value of an element using a variable name for the array.

$fred = "hello";
$var_name = 'fred';
echo $$var_name;

This works fine and prints "hello".

$fred = array("item" => "hello");
$var_name = 'fred["item"]';
echo $$var_name;

or
echo ${$var_name}

Any suggestions? Using Php-4.1.0

You probably need to do this:

echo ${$var_name};
