Vscode-intelephense: Problems running intelphense 1.3.11 with elementor extension on WSL-2 Ubuntu 18.04

[mwoodpatrick]

I'm seeing some unexpected errors when using intelphense 1.3.11 with elementor extension on WSL-2 Ubuntu 18.04.

I'm creating a WP Elementor extension which I'm creating under namespace POSRTest I'm getting the message:

Undefined function 'is_null'.

from line:

            if ( \is_null( self::$_instance ) ) {
        self::$_instance = new self();
    }

Same issue for function version_compare, printf, sprintf.

I have tried it with & without the leading ""

Commenting out the namespace declaration does not appear to help!

try to remove the trailling back space, it should work. as far as I know. the is_* other function will result the same error when using trailling backslash

@mwoodpatrick Checklist:

• check that there are items in intelephense.stub setting - there should be 50+ names, mentioned functions are under standard
• try to reindex workspace: Command palette (F1) -> Intelephense: Index workspace
• Check if there is something weird in intelephense output: Toggle output Ctrl+Shift+U -> select: intelephense

I know there's global names pace. But every time it will gone normally. I always remove the on built in isset, is_* for about 2 years using intelephense.
