Lint Old PHP Using Docker For Visual Studio Code

.vscode\settings.json

{
    "php.validate.executablePath": "scripts/php.sh"
}

README.md

I am working on a project that is using a very old version of PHP, and I wanted to set up linting for it in the Visual Studio Code editor without having to install PHP 5.3 on my system. This setup seems to work pretty well.

scripts\php.sh

#!/bin/sh

cat $8 | docker run --rm -i php:5.3 php -l -n -d display_errors=On -d log_errors=Off
