With the use statement.
If static methods that's all you need. If instance methods you need a new instance of the class injected.
If straight php, lookup the require and include statements.

How can I include a php file in a function?
I'll try to explain my need more simply) I have several parsers, each of which has its own file with the necessary functions. When the function starts, I need to load this file with functions for it to work. How can I do this?
Let's assume a file with functions like this:
<?php
function getCategory ($catId) {
if ($catId == '123') {
return 'phones';
} else {
return 'laptops';
}
}
The method in the controller looks like this:
class ParserController extends Controller
{
public function getData($id)
{
$model = Parser::find($id);
include(Storage::disk('local')->get('parsers/functions/' . $model->id . '-' . $model->title . '.php'));
dd(getCategory('123'));
}
}
I'm getting this error. It seems to be reading the file, but I can’t use the functions from it.
ErrorException include(<?php function getCategory ($catId) { if ($catId == '123') { return 'phones'; } else { return 'laptops'; } } ): failed to open stream: No error
What am I doing wrong?

@jlrdw I try require and include - I get the same error (

This is a pretty stinky code smell, but,
include(Storage::disk('local')->path('parsers/functions/' . $model->id . '-' . $model->title . '.php'));
You should test if the function exists before calling the function and catch errors
But really? Include files? I am sure there are MULTIPLE better ways to do this

@Snapey I smell this smell too)) But I can’t choose a more suitable option. And I don’t understand why it doesn’t work with include

@rediska Why not just use classes and methods properly?
Encapsulate your logic in a proper class, instead of trying to horribly include random functions from random files.

@martinbean I have a shared php file. I create a new class and use it as expected.
<?php
namespace App\Modules;
use Illuminate\Support\Arr;
class Functions
{
static function getSale($oldPrice, $price)
{
...
}
}
And I address him this way:
Functions::getSale(100,50);
It works. But now I have a different task. I can't use use App\Modules\Functions; in the controller or model. I only need to load one file, the name of which I define in the function itself.

@Rediska first sentence here https://laracasts.com/discuss/channels/laravel/how-can-i-include-a-php-file-in-a-function?page=1&replyId=912887
use App\Modules\Functions; /// change to actual namespace you use.
And since static, just use it as needed.

@rediska maybe something like this would make more sense?
First create your parser functions as classes, than add a new column on your parsers table with the $parser::class namespace for each parser.
class Parser extends Model
{
public function parse($input)
{
$parser = app($this->handler); // $parser->handler = App\Modules\Parsers\CategoryParser;
return $parser->parse($input);
}
}
```
