PHP lambdas: Bitch & Whine.

Name: Anonymous 2008-10-12 19:51

Why the FUCK can't I assign functions to magic methods?

% php -r 'class Whut{function __construct(){ $this->__call = function ($m, $v) { echo "Calling: ", $m; }; } } $n = new Whut; $n->whut();'

Fatal error: Call to undefined method Whut::whut() in Command line code on line

1

Wait, I can't even use them as methods?

% php -r 'class Whut{function __construct(){ $this->__call = function ($m, $

v) { echo "Calling: ", $m; }; } } $n = new Whut; $n->__call("whut", array());'

Fatal error: Call to undefined method Whut::__call() in Command line code on lin

e 1

And, dude, what the shit!?

% php -r 'function lol(){return function () {echo "Hello."; }; } lol()();'

Parse error: syntax error, unexpected '(' in Command line code on line 1

Ok, how about...

% php -r 'function lol(){return function () {echo "Hello."; }; } (lol())();                       $n();'

Parse error: syntax error, unexpected '(' in Command line code on line 1

So, I abso-fucking-lutely have to assign it?

% php -r 'function lol(){return function () {echo "Hello."; }; } $n = lol();

 $n();'

Hello!

Oh, screw you, god damn faggots.

$ php -r 'class N { function __construct($f) { $this->___call=$f; } } $a = new N(create_function("", "return 1;")); $a->__call();'



Fatal error: Call to undefined method N::__call() in Command line code on line 1

Spoilers: PHP does not work that way.

Object-oriented PHP is a sad disorder.

What the fuck, PHP. Classes don't fucking have functions, they have methods. What the fuck. I can't fucking believe this. Ugh, I'm so fucking mad at PHP right now. Fuck this.

Methods are just functions belonging to a struct.

structs can contain function pointers, but not functions.

If you want to get technical, there are no such things as methods or structs or classes. Just functions which take in an additional pointer to some allocated space.
Doesn't sound so hot now, does it punk?

Oh look, how cute, a seppler! He sees the world in bits and bytes. He deals not in abstractions more powerful than the occasional vtable.

He also probably gets shit done, and makes money doing it, unlike the basement dwelling faggots who seem to comprise most of the population of /prog/

Because C++/Javaers with their broken object systems and feckless patterns are known for being masters of not tediously reimplementing trivial functionality and getting shit done.

I notice it's slow and buggy, and took more time and money to develop than they ever wanted it to. Step 3 is: write your programs in Lisp instead.

I notice that it's written in C.

There is no such thing as functions, just memory locations and a return address on the stack.

There's no such thing as a stack, just instructions to load or store a value using indirect addressing and increment or decrement the index register.

There is no such thing as matter, only strings vibrating.
