Re: [RFC] [PHP 6] Uniform Variable Syntax

The advantage of the proposed behaviour is that it can be easily explained to *new* users of the language, as it's internally consistent, which appears not to be true of the old - an example in the RFC being |Foo::$bar[1][2][3] vs ||Foo::$bar[1][2][3]()|

A simpler example of the current logic's inconsistencies: $foo = 'foo'; $bar->$foo = array(); $bar->$foo[0] = 42; // $bar now has an array on ->foo, and an integer on ->f http://3v4l.org/pImS3 Not only does this not feel consistent in itself, it's different if you do the same thing with an object: $foo = 'foo'; $bar->$foo = new stdClass; $bar->$foo->x = 42; // $bar now has a single property ->foo, which is an object with property ->x http://3v4l.org/DUaJj Other than "it's always worked this way", I can't think of a good justification for this difference. -- Rowan Collins [IMSoP]
