Usage in applications

1. Install as dependency

composer require luk-z/api-proxy-php

1. Add custom includes To add custom Controllers and Routes just define these constants:

1. Copy the environment file:

cp .env.example .env

Required define

In order to work the following php define should be defined:

• APP_TABLE_APPS

These php defined are optional

• APP_ADD_DEFAULT_ROUTES: add default hello world and test routes
• APP_CUSTOM_INCLUDES_PATH
• APP_CUSTOM_ROUTES_PATH

Requirements

• PHP 7.3 or higher

Development

Setup local machine

To install dependencies php 7.3+ and composer are needed. Instead installing them in the local machine use a dockerized composer (requires Docker Desktop).

Create php and composer aliases following this guide.

1. Clone the repository:

git clone https://github.com/lukzed/api-proxy-php.git project_name && rm -rf ./project_name/.git
cd project_name

1. Install suggested vscode extensions

2. Copy the php-cs-fixer-wrapper.sh file:

cp php-cs-fixer-wrapper.sh.example php-cs-fixer-wrapper.sh

change WORKSPACE_ROOT="<absolute path to your workspace>" inserting the application absolute path (use pwd command to obtain absolute path)

1. Install dependencies:

composer install

Running the Application

Start the development server:

php -S localhost:8000 -t public

The application will be available at http://localhost:8000.

Development Tools

Code Quality and Formatting

This project includes PHP linting and formatting tools that work seamlessly with Visual Studio Code.

Tools Included

• PHP_CodeSniffer (PHPCS): Linter for detecting coding standard violations (PSR-12)
• PHP CS Fixer: Automatic code formatter
• PHPUnit: Testing framework for unit and integration tests

Visual Studio Code Setup

1. Install the recommended extensions when prompted, or manually install:

   • PHP CS Fixer (junstyle.php-cs-fixer)
   • PHP_CodeSniffer (ikappas.phpcs)
   • PHP Intelephense (bmewburn.vscode-intelephense-client)

2. The workspace settings (.vscode/settings.json) are pre-configured to:

   • Enable format on save
   • Run PHP CS Fixer automatically
   • Show PHPCS violations in real-time

Command Line Usage

Check for coding standard violations:

composer lint

Automatically fix coding standard violations:

composer lint:fix

Format code using PHP CS Fixer:

composer format

Check what PHP CS Fixer would change (dry run):

composer format:check
