@suppress is not working (May 2026)

PabloCastellazzi

Hello,

First of all, apologies, i posted in a closed discussion by mistake.

I can't get @suppress to work. Please see the screenshots bellow.

I am experience the issue with v1.70.18851. Default configuration, except for php_diagnostic = warning in .editorconfig.

PabloCastellazzi, thank you for the question.

Your setup looks unusual - we don't underline the PHP0421 warning, we only dim it:

suppress

Isn't it possible that you have .editorconfig file with additional settings? or settings.json overriding the default "php.problems" setting? (more at https://docs.devsense.com/vscode/problems/suppressing-diagnostics/)

PabloCastellazzi good idea! will be implemented.

One other thing, i tried to use $_ which is more or less universally accepted as "the developer know this variable is unused" and it does not work either. Can we get this as a feature?

Hello, sorry for the delay, i did not notice i have to opt-in into notifications.

This are my current settings. Nothing related to php.problem.*. I checked with php.problem @modified and there not changes.

{
    "php.format.rules.declCompactEmptyBody": true,
    "php.format.rules.importSorting": "alphabetic",
    "php.format.rules.importSortingCaseSensitive": true,
    "php.format.rules.keepClassesOnOneLine": true,
    "php.format.rules.openBraceOnNewLineForAnonymousClasses": false
}

[*.php]
php_diagnostic_php6602 = false
php_diagnostic = warning

I also have disabled the php builtin extension.

PabloCastellazzi, thank you.

It looks like we (incorrectly) prioritize the .editorconfig's php_diagnostic = warning over the @suppress tag.
