Hey,
<?php
error_reporting(E_ALL);
echo $$foo;
?>
results in
Notice: Undefined variable: foo in /foo/bar.php on line 4
Notice: Undefined variable: in /foo/bar.php on line 4
Wouldn't it be more appropriate if the second notice was something like
"Notice: Undefined variable: <unnamed> in /foo/bar.php on line 4"?

i'd prefere to put the variable name in single quotes here
as the name actually is '' (empty string)
<?php
$foo = "";
$$foo = "hallo";
echo ${""};
?>

Would be a lie... $foo WILL evaluate to the empty string which used like
this, although it does look weird, it is right :)
