Description:
------------
This does not work as expected:

$array = array('one','two','three');
$arraypath = 'array[1]';
echo ${$arraypath};

Workaround:

$array = array('one','two','three');
$arraypath = 'myarray[1]';
eval('$value = $'.$arraypath.';');
echo $value;

BUT:

The workaround DOES NOT work inside a function.

Reproduce code:
---------------
$array = array('one','two','three');
$arraypath = 'array[1]';
$value = showit($arraypath);

function showit($arraypath)
{
    eval('$value = $'.$arraypath.';');

    echo $value;        // Attempt #1
    echo $$arraypath;   // Attempt #2
    echo ${$arraypath}; // Attempt #3
}

Expected result:
----------------
nothing

Actual result:
--------------
nothing
