PHP 8 in Visual Studio Code

Question

I use the latest Version of Visual Studio Code (1.52.1) with PHP Intelephense 1.5.4 on Ubuntu. Despite it is the latest Version it seems not to know the new PHP 8 Syntax. For example it shows an error when using the nullsafe operator:

$myobject?->myfunction();

Is there a way to teach VSC PHP 8 or do we have to just wait for an update?

Answer 1

You should point Visual Studio Code to the location of PHP interpreter that you want to use.

You can do it by setting a line in the settings.json like this:

"php.validate.executablePath": "c:/usr/php8.1/php.exe",

It is a VSCode configuration option but seems to work with Intelephense too.

You can also do it on per project basis using a separate settings.json file residing in project's .vscode folder. You can find more on these options in the VSCode documentation.

As you can see on https://github.com/bmewburn/vscode-intelephense/milestone/26: they are actively working on adding support for PHP8. Any further questions should be posted in their issue tracker

This answer solved my problem, even tho i don't use a mac.

I still had an old php version linked in my VSCode settings of my WSL integration (settings.json). Removing that line, fixed the errors.
