Visual Studio Code PHP Intelephense Keep Showing Not Necessary Error - php

Question

After the latest update of PHP Intelephense that I get today, the intelephense keep showing an error for an undefined symbol for my route (and other class too), there is no error like this before and it's bothering me.
Here is the error screenshot :
And this is my code :
Route::group(['prefix' => 'user', 'namespace' => 'Membership', 'name' => 'user.'], function () {
Route::get('profile', 'ProfileController#show')->name('profile.show');
Route::patch('profile', 'ProfileController#update')->name('profile.update');
Route::patch('change-password', 'ChangePasswordController#change')->name('change-password');
Route::get('role', 'ProfileController#getRole')->name('profile.role');
Route::get('summary', 'SummaryController#show')->name('summary');
Route::get('reserved', 'AuctionController#reservedAuction')->name('reserved');
});
Actually there's no error in this code but the intelephense keeps showing an error so is there a way to fix this?

Answer 1

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.

Answer 2

Version 1.3.0 has flaw IMO.
Downgrade to version 1.2.3 fixes my problem.
I'm on
Laravel 5.1
PHP 5.6.40

Answer 3

use Illuminate\Support\Facades\Route;
Warning Disappeared after importing the corresponding namespace.
Version's
Larvel 6+
vscode version 1.40.2
php intelephense 1.3.1

Answer 4

If you see this immediately after adding a new Vendor class, be sure to run the VScode command (control-shift-P) Index Workspace

Answer 5

In my case, for some reason, vendor folder was disabled on VS Code settings:
"intelephense.files.exclude": [
"**/.git/**",
"**/.svn/**",
"**/.hg/**",
"**/CVS/**",
"**/.DS_Store/**",
"**/node_modules/**",
"**/bower_components/**",
"**/vendor/**", <-- remove this line!
"**/resources/views/**"
],
By removing the line containing vendor folder it works ok on version Intelephense 1.5.4

Answer 6

This solution may help you if you know your problem is limited to Facades and you are running Laravel 5.5 or above.
Install laravel-ide-helper
composer require --dev barryvdh/laravel-ide-helper
Add this conditional statement in your AppServiceProvider to register the helper class.
public function register()
{
if ($this->app->environment() !== 'production') {
$this->app->register(\Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider::class);
}
// ...
}
Then run php artisan ide-helper:generate to generate a file to help the IDE understand Facades. You will need to restart Visual Studio Code.

Answer 7

You don't need to downgrade you can:
Either disable undefined symbol diagnostics in the settings -- "intelephense.diagnostics.undefinedSymbols": false .
Or use an ide helper that adds stubs for laravel facades. See https://github.com/barryvdh/laravel-ide-helper

Answer 8

1.3.1 fixed it.
Just update your extension and you should be good to go

Answer 9

There is an other solution since version 1.7.1 (2021-05-02)
You can now tell where intelephense should look for a dependency, for example vendor which is the most common.
"intelephense.environment.includePaths": [
"vendor"
],
Furthermore, it even bypass the VSCode rule
"files.exclude": {
"**/vendor": true
},
You can read more in the changelog here

Answer 10

To those would prefer to keep it simple, stupid; If you rather get rid of the notices instead of installing a helper or downgrading, simply disable the error in your settings.json by adding this:
"intelephense.diagnostics.undefinedTypes": false

Answer 11

Here is I solved:
Open the extension settings:
And search for the variable you want to change, and unchecked/checked it
The variables you should consider are:
intelephense.diagnostics.undefinedTypes
intelephense.diagnostics.undefinedFunctions
intelephense.diagnostics.undefinedConstants
intelephense.diagnostics.undefinedClassConstants
intelephense.diagnostics.undefinedMethods
intelephense.diagnostics.undefinedProperties
intelephense.diagnostics.undefinedVariables

Answer 12

This is really a set of configurations for your editor to understand Laravel.
If you want to configure it all manually, here is the repo. This is for both VS code and PhpStorm.
Or if you want you can download this package.(I created) recommended to install it globally.
And then just run andylaravel setupIDE. this will configure everything for you according to the fist repo.

Answer 13

No, the errors occurs only after the Intelephense extension is automatically updated.
To solve the problem, you can downgrade it to the previous version by click "Install another version" in the Intelephense extension. There are no errors on version 1.2.3.

Answer 14

Had same problem in v1.7.1. It was showing error on built-in functions. But just found the solution: go to extension setting #ext:bmewburn.vscode-intelephense-client and disable one by one Intelephense›Diagnostics: and you will see the error showing will stop.

Answer 15

For anyone going through these issues and uneasy about disabling a whole set of checks, there is a way to pass your own custom signatures to Intelephense.
Copied from Intelephese repo's comment (by #KapitanOczywisty):
https://github.com/bmewburn/vscode-intelephense/issues/892#issuecomment-565852100
For single workspace it is very simple, you have to create .php file
with all signatures and intelephense will index them.
If you want add stubs globally, you still can, but I'm not sure if
it's intended feature. Even if intelephense.stubs throws warning about
incorrect value you can in fact put there any folder name.
{
"intelephense.stubs": [
// ...
"/path/to/your/stub"
]
}
Note: stubs are refreshed with this setting change.
You can take a look at build-in stubs here:
https://github.com/JetBrains/phpstorm-stubs
In my case, I needed dspec's describe, beforeEach, it... to don't be highlighted as errors, so I just included the file with the signatures /directories_and_paths/app/vendor/bin/dspec in my VSCode's workspace settings, which had the function declarations I needed:
function describe($description = null, \Closure $closure = null) {
}
function it($description, \Closure $closure) {
}
// ... and so on

Answer 16

use Illuminate\Support\Facades\Route;
Add the above Namespace

Answer 17

In your web.php
Add this line of code
use Illuminate\Support\Facades\Route;
Then you are done, again if you got Auth error then add this line of code
use Illuminate\Support\Facades\Auth;
Thanks.

Answer 18

The only working solution I found is:
Set language mode to Blade (use extension: Laravel Blade formatter)
It will resolve the issue. Otherwise, follow this procedure.
These classes don't exist in the workspace. Laravel creates them at runtime. As such they are reported as undefined. The solution is to either provide stub definitions
https://github.com/barryvdh/laravel-ide-helper
or turn off the diagnostics (intelephense.diagnostics.undefinedTypes).

Answer 19

I had the same issue and the following seemed to have addressed the issue.
a) Updated to latest version 1.3.5 and re-enabled all the diagnosis settings.
I was still getting the messages
b) Added the vendor folder with the dependent libraries to the workspace
This seems to have solved the problem.

Answer 20

I recently fixed my own issue. by going file > preferences
and I search for intelliphense
The section that has file to exclude, I noticed vendor folder was added.
I removed it, now all my laravel files are indexed
