[POLL] Do you like "then,do,end" or "{ }"?

Even in PHP!

Code: Select all

$obj->doFunction()->doOtherFunction()->doEvenMoreFunctions()->etc()->etc()->andSoOn();

Awesome! I thought it was just Java! I'd never seen anyone do it in another language! How would you do it in Lua, though. I was trying for about 20 minutes and couldn't figure it out :O

Oh, so they fixed that bug in PHP where a function call wasn't a proper expression?

This is one way:

Code: Select all

local X = {}

function X:foo()
    -- do stuff
    return self
end

function X:bar()
    -- do other stuff
    return self
end

function X:hodor()
    -- hodor
    return self
end

X:foo():bar():hodor()

Guess so. It's probably been fixed for a while, I've never seen it not work. But then, I've only really worked with PHP for about 4 years.

They even fixed the one where you can immediately access an array return value without storing it in a variable. AND they included closures.

So now you can do this:

Code: Select all

$this->func()['funcs']['func']()['func']()['func']()['key']['otherkey']()()();

I'm not sure if that would really make anyone happy, but it can technically be done

[DaedalusYoung]

That looks awful, tbh. Why would I want to do that? Can't you just do each call separately?

[Plu]

Yeah this example is a huge mess, just for the heck of it

Normally you'd more likely do something like this:

Code: Select all

$firstName = $obj->getNames()[0];

Which is kinda neat and cleaner than

Code: Select all

$names = $obj->getNames();
$firstName = $names[0];

[DaedalusYoung]

Well yes, that would make more sense. Although in that example, I would just code the getNames() function to include an argument to get the desired output, so:

Code: Select all

$firstName = getNames('first')

[Plu]

Yeah, still just an example. In this case it isn't really neccesary, but especially when dealing with PHP internal functions it can be useful to make the direct modification.

Plus, it breaks your concentration when something that seems to make sense doens't work, at least for me.
