Cannot use positional argument after named argument in PHP

Question

<?php

use App\Http\Controllers\HomeController;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AdminPanel\HomeController as AdminHomeController;

Route::post(uri:'save',[HomeController::class,'save']);
Route::get(uri:'/admin',[AdminHomeController::class, 'index']);

Why can't i use this parameters ? Why am i getting this error i have no idea.

Answer 1

Good old-fashioned positional parameters are identified by, well, their position. On the other side, named parameters can be shuffled because its their name what defines what they are:

function foo($a, $b) {
    var_dump($a, $b);
}
foo(10, 20);
foo(b: 20, a: 10);

Both calls print the same result:

int(10)
int(20)

However, if you mix them, there's no way to reliably determine what parameters you mean:

foo(b: 20, 10); // Is 10 the second parameter ($b)?

Yes, PHP could have implemented complex rules to resolve any ambiguity, but that would be unlikely to enhance code readability.

So... you need to pick one: named or positional.
