How do I correct syntax highlight in VS Code for PHP 8.1 Enum Class?

Question

My Code:

namespace App\Enum;

enum HomeStatus: string
{
    case RENT = 'rent';
    case MOVE_IN = 'move_in';
    case SOLD = 'sold';
    case COMING_SOON = 'coming_soon';
}

The code above is executing and working but the editor has the following error:

Unexpected 'Name'. Expected ';'.intelephense(1001)

I am using Intelephense v1.8.0 which I believe is the latest.

In the Change Log it says:

PHP 8.1 is now the default version.

I'm thinking that either that's not the case or PHP 8.1 does not yet have support for enums.

Is there a way to resolve this or is this something that is not yet supported?

EDIT As requested here's a screenshot of the error.

That error doesn't seem to be here, since there is no Name showing in your code. Can you show the code giving that error? – Johann

@Johann I agree the quotes are misleading, but that's seemingly the internal token name used by the language server. For example, if you type class Foo {, the error reads Unexpected 'EndOfFile'. – Tetchy

Answer 1

Open Visual Studio Code settings and ensure the intelephense.environment.phpVersion directive is set to "8.1.0" or greater. It can be set for the whole program or for specific projects.

{
    "intelephense.environment.phpVersion": "8.1.0"
}

Thank you, this solved my problem. I went into settings.json and I added "intelephense.environment.phpVersion": "8.1.0" – Gymnosperm

Answer 2

For me, Alvaro's solution was only half of the fix. I also had to update this setting to point to my PHP executable.

{
"php.validate.executablePath": "C://laragon//bin//php//php-8.1.3-Win32-vs16-x64//php.exe"
}

This doesn't work when using WSL – Keelykeen

This setting doesn't belong to PHP Intelephense, it's from builtin PHP Language Features which, according to Quick Start, needs to be disabled. – Tetchy
