Use of {} with member.

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, -- Yasuo Ohgaki yohgaki@ohgaki.net
