Visual Studio Code

Visual Studio Code (VSCode) is a source code editor developed by Microsoft for Windows, Linux and MacOS (including M1 Macs). It includes support for debugging, embedded Git control and GitHub, syntax highlighting, intelligent code completion, snippets, and code refactoring.

The main characteristic of the editor is that it is extensible and it has a huge collection of extensions maintained by users and by Microsoft itself. See details at the VSCode Extensions for Visual Studio Code website.

As a general introduction, this is a presentation about the topic Joomla Development with Visual Studio Code, by René Kreijveld, Joomla developer Destiny B.V. Joomla User Group London, 16th march 2021.

On this page, we detail a list of recommended extensions to configure VSCode to support PHP and Joomla.

This is a list of extensions to support PHP on VSCode:

• PHP Debug felixfbecker.php-debug. Debug support for PHP with Xdebug.
• phpcs ikappas.phpcs. PHP CodeSniffer for Visual Studio Code.
• PHP Intelephense bmewburn.vscode-intelephense-client. PHP code intelligence for Visual Studio Code. Alternative: PHP IntelliSense felixfbecker.php-intellisense
• PHPUnit emallin.phpunit. Run PHPUnit tests from VSCode.
• phpfmt kokororin.vscode-phpfmt. The missing phpfmt extension for Visual Studio Code. The phpfmt formatter can parse and format even a PHP file version 4 if needed.
• php cs fixer junstyle.php-cs-fixer: In case of opting for the PSR-2: Coding Style Guide). PHP CS Fixer extension for VS Code, PHP formatter, PHP code beautify tool, format HTML.
• PHP Namespace Resolver MehediDracula.php-namespace-resolver: PHP Namespace Resolver can import and expand your class. You can also sort your imported classes by line length or in alphabetical order.
• PHP Phan (Analyzer) tysonandre.php-phan. Phan - static analyzer for PHP, minimizing false positives.
• phpmd linyang95.phpmd. VS Code extension for PHP, using PHPMD.

The Git protocol is natively supported on VSCode. However, there are extensions to improve code and repository management. This is a list of featured extensions for this task:

• Git History donjayamanne.githistory: Git History, Search and More (including git log).
• GitHub KnisterPeter.vscode-github: This VSCode extension integrates with GitHubExtensions for Visual Studio Code
• GitHub Pull Requests and Issues GitHub.vscode-pull-request-github: Review and manage your GitHub pull requests and issues directly in VS Code
• gitignore codezombiech.gitignore: A extension for Visual Studio Code that assists you in working with .gitignore files.

This is a list of extensions to support Joomla on VSCode:

• Joomla Snippets anibalsanchez.vs-code-joomla-snippets. Snippets for Joomla including Joomla 3.x and Joomla 4 Snippets.
• PHP Getters & Setters phproberto.vscode-php-getters-setters. Create PHP getters and setters from class properties.

This is a list of extensions to support remote SSH development:

• Remote - SSH ms-vscode-remote.remote-ssh: The Remote - SSH extension lets you use any remote machine with an SSH server as your development environment. This can greatly simplify development and troubleshooting in a wide variety of situations. For more information: Remote development over SSH
• Live Share MS-vsliveshare.vsliveshare: Visual Studio Live Share enables you to collaboratively edit and debug with others in real-time, regardless of what programming languages you're using or app types you're building. It allows you to instantly (and securely) share your current project, and then as needed, share debugging sessions, terminal instances, localhost web apps, voice calls, and more!

This is a list of handy extensions highly recommended to ease the development:

• EditorConfig for VS Code editorconfig.editorconfig EditorConfig Support for Visual Studio Code.
• change-case wmaurer.change-case: Quickly change the case (camelCase, CONSTANT_CASE, snake_case, etc) of the current selection or current word.
• Project Manager alefragnani.project-manager: It helps you to easily access your projects, no matter where they are located. Don't miss those important projects anymore.

PHP Debug Configuration

The extension supports the most common configurations of PHP Xdebug. It fully integrates all VSCode features to debug PHP scripts.

To configure the extension, visit the official documentation.

As a sample configuration for VSCode debugging, this is a common launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://code.visualstudio.com/docs/editor/debugging#_launch-configurations
    "version": "0.2.0",
    "configurations": [

        {
            "name": "Listen for Xdebug",
            "type": "php",
            "request": "launch",

            // Server Remote Xdebug Port - 9003 is the default Xdebug port
            "port": 9003,

            // Server Remote Path -> Local Project Path
            "pathMappings": {
                "/app/www": "${workspaceRoot}/www"
            }
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",

            // Local Xdebug Port - 9003 is the default Xdebug port
            "port": 9003
        }
    ]
}

Related to the launch.json configuration that felixfbecker/vscode-php-debug requires, it is the configuration of PHP Xdebug itself.

Your development environment should have Xdebug 3. (Xdebug 2 is no longer supported.) To configure PHP Xdebug, these are the most common settings for php.ini:

Xdebug 3 Configuration

[Xdebug]
;;;;;;;;;;;;;;;;;;;
; xdebug-3.0.0
; https://xdebug.org/docs/upgrade_guide
;;;;;;;;;;;;;;;;;;;
xdebug.mode = debug
xdebug.start_with_request = yes
xdebug.discover_client_host = true
; xdebug.client_port = 9003

To know more about how Xdebug works internally to connect to the Editor, check the Xdebug 3 — Documentation.

phpcs Configuration

To configure the extension, visit the official documentation.

The extension supports the most common configurations of PHP_CodeSniffer.

By default, PHP_CodeSniffer comes with several coding standards. Once the extension is installed, it works with PSR2.

    "phpcs.standard": "PSR2",

To configure the extension to apply the Joomla! Coding Standards, install the rules following the official guide.

Once Joomla! Coding Standards is installed, configure the User Settings following this sample configuration:

    "phpcs.standard": "/home/YOUR-USER/.../Joomla",

Configuration of PHP Intelephense

To configure the extension, visit the official documentation.

The extension does not require additional configuration.

VSCode comes with basic support of the PHP language. It is a good idea to disable the default support to avoid conflicts:

    // Disable basic suggestions
    "php.suggest.basic": false,

    // To activate code suggestions in comments
    "editor.quickSuggestions": { "comments": true },

As an alternative, it is also a popular extension: PHP IntelliSense felixfbecker.php-intellisense Advanced Autocompletion and Refactoring support for PHP.

PHPUnit Configuration

To configure the extension, visit the official documentation.

The extension integrates PHP Unit with VSCode, so all features of PHP Unit are integrated with VSCode and can also be parameterized for further integration with the user interface.

This is a sample configuration of the extension:

    "phpunit.preferRunClassTestOverQuickPickWindow": true,
    "phpunit.driverPriority": [
        "Path",
        "Command",
        "Composer",
        "Phar",
        "Ssh",
        "GlobalPhpUnit"
    ],

PHP CS Fixer Configuration (Only for PSR2)

To configure the extension, visit the official documentation.

The extension integrates PHP CS Fixer with VSCode, so all features of PHP CS Fixer are integrated with VSCode and can also be parameterized for further integration with the user interface.

To automatically apply PHP CS Fixer to PHP files, configure the user settings in this way:

    "[php]": {
        "editor.defaultFormatter": "junstyle.php-cs-fixer",
    },
    "php-cs-fixer.onsave": true,

PHP Phan (Analyzer) Configuration

To configure the extension, visit the official documentation.

This is a sample configuration of the extension:

    "phan.phpExecutablePath": "/usr/bin/php",
    "phan.analyzedFileExtensions": [
        "php"
    ],

phpmd Configuration

To configure the extension, visit the official documentation.

The extension does not require additional configuration.

This is a sample configuration of the extension:

    "phpmd.command": "php /home/YOUR-USER/.../phpmd/phpmd.phar",
    "phpmd.rules": "/home/YOUR-USER/.../phpmd-rulesets/phpmd_config.xml",

Configure EditorConfig for VS Code

EditorConfig is a file format and collection of text editor plugins for maintaining consistent coding styles between different editors and IDEs.

To configure the editor according to your preferences, create a file .editorconfig:

; EditorConfig helps developers define and maintain consistent
; coding styles between different editors and IDEs.
