Description:
------------
As I had previously reported here (http://bugs.php.net/bug.php?id=39150), PHP does in fact allow the creation of variables and constants with names that contain invalid characters. As far as I can tell, PHP will let you create a variable or constant with any string whatsoever, even a binary one. Whether or not it is desirable to allow this behavior is not the point of this report; but if it is desirable, or if it's not going to be fixed, could the docs please be updated to clarify the fact that you *can* use invalid variable/constant names?

$GLOBALS['2a'] is an array key which is not restricted. define() documentation doesn't restrict name either. Only for handy use through $var_1 or CONST_1 rules are defined in the language chapter.
