We at least warn in common cases now (instead of E_STRICT)

bwoebi

@LeviMorrison Googled it, could not find it.

@LeviMorrison Well, on these I agree that tehy warn/error

Levi Morrison

Your example also warns/is strict.

bwoebi

My example doesn't warn

@Levi note that in my example I just remove the arg

Levi Morrison

I just copied it to 3v4l and reformatted: 3v4l.org/niLjI

/afk for a bit

bwoebi

oh, php -r … it's using 5.5 (not master)

@LeviMorrison why does that one even warn/error?

I mean, it's not a LSP violation as per PHP standards?

Levi Morrison

12:19 AM

IMO it should be.

I want to unify internal and userland functions and passing too many is a mistake.

(side with internals, not userland)

bwoebi

@LeviMorrison I strongly disagree

More often than a too-many-args helped, I had to wrap the callable in a dummy Closure because it was an internal function

Levi Morrison

strlen($a, $b) <- what's that supposed to even mean?

bwoebi

this, nothing

Levi Morrison

It's an error, clearly, and passing it to a higher order function which will call it with 2 parameters is no different.

bwoebi

$cb = "strlen";
$cb($a, $b); // I pass my callable two args. Caller decides it just needs to return length of first arg and passes strlen

I am okay with warning on direct calls, but disagree with warning on dynamic calls

I'm pretty sure you'll break so many callbacks then, if you'd enforce it.

Levi Morrison

12:28 AM

Yes. That is the whole point.

bwoebi

huh?

Why … would you want that.

Levi Morrison

You think most of the time people do this intentionally?

bwoebi

Yes.

Levi Morrison

Strongly disagree there.

bwoebi

Because they do not care about these args.

Levi Morrison

12:29 AM

Not caring about args is how you have errors.

It shoudl be explicit, 100%.

bwoebi

I explicitly do not care about that arg by omitting it

Levi Morrison

The code is no different in that case than doing it accidentally, which is my point.

If you do not care the code should explicitly reflect it, not implicitly just ignore it.

I am okay with warning on direct calls, but disagree with warning on dynamic calls

Levi Morrison

That's not explicit.

strlen($a, $b) shoudl have the same semantics as ('strlen)($a,$b) or $unique_var_1 = 'strlen'; $unique_var_1($a, $b).

bwoebi

@LeviMorrison In that case I prefer no warnings/errors at all

Levi Morrison

12:32 AM

There's nothing about a function boundary that changes any of that, especially because if you implement the semantics you are talking about then in-lining will be broken for them.

And inlining is critical for future performance improvements.

bwoebi

because the benefit in the dynamic case is vastly superior to rarely catching accidentally too many passed arguments.

@LeviMorrison how does that affect inlining?

Levi Morrison

because of chat.stackoverflow.com/transcript/message/34733095#34733095

After inlining it is equivalent to the last case.

bwoebi

oh, you mean constant variable value propagation?

Levi Morrison

No, I mean inlining.

The cases above are about constant propagation, yes.

But once you inline it is equivalent to the variable assignment and then calling it.

bwoebi

Yeah, in that case we should remove the too-many-args from internals

Levi Morrison

12:36 AM

I don't know why you'd want PHP to be any sloppier than it already is.

bwoebi

Because it's worth the dynamics we gain?

Levi Morrison

Masking errors? No way.

We have enough of that already with type juggling.

bwoebi

We mask 10% errors for 90% more potential … sounds like a benefit

Noobie

@sliver :D no worries, take your time. I am doing my part for the research anyways

bwoebi

@Levi I think we two won't agree on this…

@Ocramius quick reminder: chat.stackoverflow.com/transcript/11?m=34528284#34528284

@Ocramius I also reiterate: chat.stackoverflow.com/transcript/11?m=34406546#34406546

Hey all, First time on here this evening. Hope everyone is well. Just wondering if anyone is clued up on the Walker Classes? I have been following a YouTube tutorial and as soon as I get to the stage, as outlined in the link, my drop down menus disappear: gist.github.com/wanttolearnnow/968ec6c3ab72ae9471daaf76fd010257

@bwoebi Can you see any opposition to truly nested multiline comments?

Robert Smith

Hello guys... I have been trying to figure out why this deserialization fails:
ini_set('session.serialize_handler', 'php_binary');
session_start();
$sess = "\x1xi:1;\x2y";
session_decode($sess);
No one seems to know why.

Levi Morrison

It's annoying ^_^

Robert Smith

It returns "session_decode(): Failed to decode session object. Session has been destroyed"

No, here it is https://github.com/marlocorridor/tracker and i followed https://getcomposer.org/doc/05-repositories.md#vcs and installed the "fix" successfully. but another error occured.
I'm puzzled because, using the old version, and changing the code on the library manually, an error would not occur.

@abcd you need to use FPDF Library at all

Travis Hallet

how can you pass an array through an html form checklist. I am trying <input type = 'checkbox' name = 'array[]' value = '$value'>... but I keep getting the err of I have an undefined index and its not showing up in the URL

@FélixGagnon-Grenier Hi there!

Félix Gagnon-Grenier

7:03 AM

oh hi!

Travis Hallet

@TetrixUser I'm getting this in the url do you know why?

services%5B%5D=Basic+Service&services%5B%5D=Shrub+Trimming

instead of services[]

Robert Smith

@FélixGagnon-Grenier I didn't see you. I just want to say hi. Actually, I wanted to ask you about my little issue with session_decode, but I think it is bit late here.

abcd

@TetrixUser thanks , that is pdf plugin , i need to install through composer and i need to try right ? is there any other option other than using pdf plugin ?

@Patrick thanks , that is pdf plugin , i need to install through composer and i need to try right ? is there any other option other than using pdf plugin ?

Félix Gagnon-Grenier

@RobertSmith same here. I am literally in bed. talk laters!

Robert Smith

@FélixGagnon-Grenier Me too. Maybe tomorrow. Bye!

Patrick

7:09 AM

@abcd you are repeating yourself... and are you not already using composer?

abcd

@Patrick no, i didt know proper procedure to install .... please guide me.....

Travis Hallet

really nead help here on something that I think is simple please

and thank you

lol

Patrick

@abcd rtfm

Travis Hallet

well I have a form with a method get. and I'm trying to pass multiple checkboxes under the same name. my code that makes the check boxes is <input type = 'checkbox' name = 'services[]' value = '$service'> and the URL for my checkbox array var is coming out to this services%5B%5D=Basic+Service&services%5B%5D=Shrub+Trimming
