It seems PHP(Zend) is looking up local (active) symbol table, since
you are accessing via vairable variable.
Can we fix this?

I tried to access the autoglobal variables via the variable variables
'trick'. But that doesn't work within functions.
Examples:
That works:
<?
?><hr><?
$test1 = '_TEST';
$test2 = '_SERVER';
$_TEST = '[test1]';
?><pre><?
var_dump( $test1 );
var_dump( ${'_TEST'} );
var_dump( ${$test1} );
var_dump( ${"$test1"} );
?><hr><?
var_dump( $test2 );
var_dump( ${'_SERVER'} );
var_dump( ${$test2} );
var_dump( ${"$test2"} );
?></pre><hr><?
That doesn't work:
<?
function foolme()
{
?><hr><?
$test1 = '_TEST';
$test2 = '_SERVER';
$_TEST = '[test1]';
?><pre><?
var_dump( $test1 );
var_dump( ${'_TEST'} );
var_dump( ${$test1} );
var_dump( ${"$test1"} );
?><hr><?
var_dump( $test2 );
var_dump( ${'_SERVER'} );
var_dump( ${$test2} );
var_dump( ${"$test2"} );
?></pre><hr><?
}
foolme();

I found that, while writing a class for processing html forms:
function __wakeup() {
$method = $this->_method;
$this->_FORM = &${"_$method"};
}
