$pages vs wire("pages") performance

[Laikmosh]

I've been using wire("pages") instead of $pages because sometimes the code is inside functions and the $pages var is not defined unless its included in the args, and i've foundin a post by Ryan that globals $var doesnt work at all in processwire, so for consistency i've been using wire('pages') anytime i need to find or get a page, but now im wondering if there might be any difference in performance from using one or the other

Or maybe im just screwing everything up and there is another way to get global vars to work inside a function in processwire?

@Laikmosh I'm not sure, but I think that there is no difference in performance between $pages, wire('pages) and pages().

There is also a third way to access API variables - functions API https://processwire.com/blog/posts/processwire-3.0.39-core-updates/#new-functions-api

wow,  didnt know these things existed, thank you very much!

one weird thing is that when i used it i got an error stating that "pages() is undefined", this function is supposed to work from 3.0.39+ and i have 3.0.98, ill chacke what might be the problem but for now i just made a function at the begining like this:

function pages() {
	return wire('pages');
};

its a temporary solution while i find out the real problem but thanks for pointing me in the right direction!

Quoting from the blog post that @Zeka linked to:

"At present, you have to tell ProcessWire you want to use the functions API by setting $config->useFunctionsAPI = true; in your /site/config.php file. Though after more testing, we may make it enabled by default in the future. If you don't have that $config property set to true, the functions are still available, but you have to prepend "wire" to them, i.e. the more verbose wirePages() rather than pages()."

And a fourth:

$this->wire->pages

I prefer this version because you don't need to activate functionsapi (and the functions api should not be used in module development), it is multi instance proof and I get IntelliSense in my IDE

Don't know which one is the best in terms of performance...
