Hi all,

I came across with bug #68947 https://bugs.php.net/bug.php?id=68947
and realized small inconsistency.

http://3v4l.org/ldZKl

$obj->${array[$key]}; // Syntax error
$obj->{$array[$key]}; // Works

$obj->${key}; // E_NOTICE. Does not work
$obj->{$key}; // Works

echo "${array[$key]}"; // Works
echo "{$array[$key]}"; // Works

Of course, script/string parsing aren't the same. Are there technical
reasons
why ${value} is not allowed? If there are, we may encourage

echo "{$array[$key]}"; // Works

rather than

echo "${array[$key]}"; // Works

Regards,
