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 here: https://github.com/felixfbecker/vscode-php-debug#installation

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://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [

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

            // Server Remote XDebug Port
            "port": 9099,

            // 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
            "port": 9099
        }
    ]
}

phpcs Configuration

To configure the extension, visit the official documentation here: https://marketplace.visualstudio.com/items?itemName=ikappas.phpcs

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: https://developer.joomla.org/coding-standards/html.html

Once the 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 here: https://github.com/bmewburn/vscode-intelephense#quick-start

The extension does not require additional configuration.

VSCode comes with basic support of the PHP language. So, it is probably 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 very popular extension: PHP IntelliSense felixfbecker.php-intellisense Advanced Autocompletion and Refactoring support for PHP.

This is a sample configuration of the extension:

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