Visual Studio Code PHP Intelephense Keep Showing Not Necessary Error

Intelephense 1.3 added undefined type, function, constant, class constant, method, and property diagnostics, where previously in 1.2 there was only undefined variable diagnostics.

Some frameworks are written in a way that provide convenient shortcuts for the user but make it difficult for static analysis engines to discover symbols that are available at runtime.

Stub generators like https://github.com/barryvdh/laravel-ide-helper help fill the gap here and using this with Laravel will take care of many of the false diagnostics by providing concrete definitions of symbols that can be easily discovered.

Still, PHP is a very flexible language and there may be other instances of false undefined symbols depending on how code is written. For this reason, since 1.3.3, intelephense has config options to enable/disable each category of undefined symbol to suit the workspace and coding style.

These options are:
intelephense.diagnostics.undefinedTypes
intelephense.diagnostics.undefinedFunctions
intelephense.diagnostics.undefinedConstants
intelephense.diagnostics.undefinedClassConstants
intelephense.diagnostics.undefinedMethods
intelephense.diagnostics.undefinedProperties
intelephense.diagnostics.undefinedVariables

Setting all of these to false except intelephense.diagnostics.undefinedVariables will give version 1.2 behaviour. See the VSCode settings UI and search for intelephense.

Solved by uninstalling and reinstalling Visual Studio Code extensions.

PHP : VS code + Intelephense detect an error on references passed in foreach (and in functions)

That was not a problem Intelephense, but with PHP IntelliSense :

I did not post an issue on intellisense Github.

Visual studio code keep showing unecesarry error

The Auth::user() return type is not the User model instance. And that's why it's shown as error. You can use comment to define the variable as an instance of the User model like,

/** @var User $ketua */
$ketua = Auth::user();

VSCode show error after use PHP Intelephense

You are using the $_POST in a wrong way.
The Intelephense think that $_POST should always use like this:

$_POST['something']
