Bug description: Variable Variables don't work properly with Arrays
Description:
------------
The 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
