Hi all,

If PHP should return NULL always against NULL variables, we may be better
to
reconsider these behavior.

[yohgaki@dev Download]$ php
<?php
$v = NULL;
$$v;


PHP Notice:  Undefined variable:  in - on line 3

[yohgaki@dev Download]$ php
<?php
$v = NULL;
$v();

PHP Fatal error:  Uncaught EngineException: Function name must be a string
in -:3
Stack trace:
#0 {main}
  thrown in - on line 3

[yohgaki@dev Download]$ php
<?php
$v = NULL;
$v[123]; // NULL



I don't care much whether these yield NULL always or raise error/exception,
but
there should be consistency.

Regards,
