OOP PHP - Call method from extended class without having to put the class for it

Question

I have a class in a file like:

class foo
{
    public function something()
    {
        return "something"
    }
}

Then in an other file I have a class like:

class bar extends foo
{

}

Now I want to call the something method. I can do this like foo::something();, but I want to just do something(). just like it is in Laravel.

Ofcourse I can require the file where foo is in, but I dont want that, because I think thats kind of dirty.

So, how do I do that? I've looked around on the internet but did not find an answer. Everthing I find is from like 5-7 years ago.

EDIT:

Look, you just return view();

Without self:: or this->

And I am wondering how you do that. IN VANILLA PHP

public function index()
{

    $categories = Category::categories();
    $posts = Post::latest()->get();

    return view('welcome', compact('posts', 'categories'));
}

Just `something()` means you're calling a function, not a class method. — u_mulder, Jan 09 '17 at 19:31
How do they do it in laravel then? :/ with the methods like view() or redirect() — Luuk Wuijster, Jan 09 '17 at 19:32
For `bar` to extend `foo` the `foo` class must be included. Then just `$this->something();` or `self::something();` — AbraCadaver, Jan 09 '17 at 19:32
@u_mulder calling methods. You can call a method in laravel without self:: or $this->. Just like you would call a function. And I want to be able to do that too. — Luuk Wuijster, Jan 09 '17 at 19:36
You would need to provide a working example, since we don't believe it. — AbraCadaver, Jan 09 '17 at 19:38
Laravel uses namespaces and `use` statements instead of `require` statements (just to respond to that specific part of your question) — jackel414, Jan 09 '17 at 19:40
Laravel helper `view()` (https://laravel.com/docs/5.3/helpers#method-view) is a wrapper for some other methods. — u_mulder, Jan 09 '17 at 19:41
`view()` is a standalone function. _The view function retrieves a view instance:_ https://laravel.com/docs/5.3/helpers#method-view — AbraCadaver, Jan 09 '17 at 19:44
Oh okay, So that means you cant have a method in the extended class and just call it like a normal function? — Luuk Wuijster, Jan 09 '17 at 19:46
Correct. And source https://github.com/laravel/framework/blob/5.3/src/Illuminate/Foundation/helpers.php — AbraCadaver, Jan 09 '17 at 19:49
Okay, thank you. sorry for my slightly stupid question... :/ — Luuk Wuijster, Jan 09 '17 at 19:52
@Luuk as I said in my answer you can do this. You can just create some kind of a wrapper and call static method from your class. — Alexey Mezenin, Jan 09 '17 at 19:56

These functions are called global helpers. You can create your own Laravel helpers in custom helpers file. Helper could be wrapper for some class method or a simle function:

if (! function_exists('customHelper')) {
    function customHelper()
    {
        return 'Something';
    }
}

To make custom helpers file work add it to autoload section of an app's composer.json and run composer dumpauto command once:

"autoload": {
    ....
    "files": [
        "app/someFolder/helpers.php"
    ]
},

Okay, thanks for you answer but, I think you misunderstood me or I was just not clear in my question, but I want to do it in vanilla php. – Luuk Wuijster Jan 09 '17 at 19:50
@LuukWuijster it's in vanilla PHP. ) These are just global functions. – Alexey Mezenin Jan 09 '17 at 19:51
