Re: [PHP-DEV] [RFC] new foo()-bar()
Hi Dmitry, 2010/11/29 Dmitry Stogov dmi...@zend.com Hi Felipe, I'm wondered it works out of the box with so small patches :) However, both patches introduce new parser conflicts and it would be grate to avoid them. I will check if there is any way to avoid it. Also the patches need to be checked for memory leaks in case of exceptions thrown from constructor and chained function(s). Yes, I already did several tests to check this. It also probably makes sense to add array deference chaining e.g. new Foo()[] (just for language consistency). Hmm, looks good to me. :) Thanks. -- Regards, Felipe Pena
Re: [PHP-DEV] [RFC] new foo()-bar()
Care should be taken in the case of new myClass()-foo() just creates an object to call a method but a static method would be more efficient here. However, well used (fluent interface for exemple) make me think +1 for that patch.

I've updated the patch with the bracketed version to include the array
dereferecing support:
http://felipe.ath.cx/diff/instance-method-call-3.patch
?php
class foo extends ArrayObject {
public function __construct($arr) {
parent::__construct($arr);
}
}
$arr = array(1, 2, 3);
$value = (new foo($arr))[1]; // int(2)

var_dump(new foo()-bar()-x); // string(3) PHP
It has some readability issues. One might assume it is
new (foo()-bar()-x)
not
(new foo())-bar()-x
As there is a mandatory space between new and its operand and no space
in front of the object operator and we allow non-constant operands to
new.
So what is
new $bar-foo();
? If I read the patch correctly this is valid and evaluated as
(new $bar)-foo();
johannes
new foo()-bar() should be read as: (new foo())-bar().
And using variable:
new $bar-y()-x should be read as: (new ($bar-y)())-x.
?php
class foo {
public $x = 1;
}
class bar {
public $y = 'foo';
}
$bar = new bar;
var_dump(new $bar-y()-x); // 1
?
I.e. just as it is nowdays.
Well, if this feature is going to be accept, we could to decide what syntax
to use.
I have created another patch which is the bracketed version of this
presented here.
?php
class foo {
public $x = 1;
}
class bar {
public $y = 'foo';
}
$x = 'bar';
$bar = new bar;
var_dump((new bar)-y); // foo
var_dump((new $x)-y); // foo
var_dump((new $bar-y)-x); // 1
?
Thus we do not have the readability issues, as pointed by Johannes.

It seems fairly handy and I've been in situations where I wanted to do
something like that - in fact, I use factories to achieve something
similar.
However, the more I use it, the more it feels like introducing code
smells into my code. You're essentially instantiating an object only
to immediately throw it away. That means you don't actually need the
object at all, you should probably be looking for static methods or
class properties. Trying to avoid statics by introducing a way to
instantiate and throw away objects in the same statement feels a lot
like reinventing OOP while adding overhead.
Anyway, just a personal observation. I generally favour the way that
PHP allows you to dig your own grave (i.e. I love the freedom of the
language), so as a developer I would probably favour this as well,
though I find it mainly a way to introduce hacks.

on same command.
Example:
?php
class bar {
public $x = 'PHP';
}
class foo extends bar {
public function bar() {
return $this;
}
}
var_dump(new foo()-bar()-x); // string(3) PHP
?
Other examples which describes the feature at

huge +1 from me ;-) It might be worth adding function call chaining
with dereferencing and instance method call chaning, like $a =
function(){ return function(){ echo 'Hello'; }; }; $a()();

Hi all,
I'm here again to presents another proposal, which adds support for
instantiating a class and calling its methods and accessing its properties
on same command.
Example:
?php
class bar {
public $x = 'PHP';
}
class foo extends bar {
public function bar() {
return $this;
}
}
var_dump(new foo()-bar()-x); // string(3) PHP

However, the more I use it, the more it feels like introducing code smells into my code. You're essentially instantiating an object only to immediately throw it away. Not necessarily; you could be calling the method for the collateral effects and that method return the object itself. This is not that uncommon. And I can do that today with a factory pattern, if I want to. Anyway, I don't want to argue against the feature, as it will just introduce a slightly shorter version of something we can already do. -- hype WWW: plphp.dk / plind.dk LinkedIn: plind BeWelcome/Couchsurfing: Fake51 Twitter: kafe15 /hype -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
