README

A simple base project for custom PHP applications.

PHPBase

Installation

$ composer create-project guyliangilsing/php-base YOUR_PROJECT_NAME HERE

Prerequisites

Before this project base can be used, the following tools and applications must be installed and accessible through the command line:

Application and tool versions

This project base has been created with the following application and tool versions:

Required PHP extensions

The following extensions must be activated inside the php.ini file:

curl
fileinfo
openssl

Running commands

Within this README file, there will be commands listed. All these commands must be run from the root directory. The root directory is the directory that this README file is located in.

Note: The version of composer does not matter, as long as it is version 2.

IMPORTANT: The listed versions have been used in the development of this project base and should work without any problems. Be mindful about other dependencies that you may add since they could not provide support for the given PHP version.

Project setup

Before the project can be started, a setup process must be done first.

Install composer dependencies

$ composer install

Create environment file

It is important that the contents of the example.env file is copied to a new .env file. The contents of the .env file are read at the start of each request to the application. Not creating this file will result in an exception error.

Webserver setup (optional)

When running this application on a webserver, make sure that the following setup process is done.

Note: For more information about a web server setup, visit the slim framework documentation.

Application root directory

The root directory of the entire application is located within the public folder. When using an external webserver, make sure that the root directory inside your configuration is set to this folder.

Request redirects

All requests should be redirected to the index.php file.

Apache

Make sure that the following apache modules are actived:

rewrite
actions

# Redirects all incomming requests (and failed file paths) to the index.php file
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]

Nginx

The following Nginx configuration can be used:

server {
    listen 80;
    server_name example.com;
    index index.php;
    error_log /path/to/example.error.log;
    access_log /path/to/example.access.log;
    root /path/to/public_folder;

    location / {
        try_files $uri /index.php$is_args$args;
    }

    location ~ \.php {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_NAME $fastcgi_script_name;
        fastcgi_index index.php;
        fastcgi_pass 127.0.0.1:9123;
    }
}

Source directory structure

All code that directly provides functionality to the main application should be placed in the src (source) directory. Within src, the following folders are placed:

App contains all application code.
Config contains all application configuration code (dependency injection setup, ORM setup, loading .env files, etc.).
Framework contains all code that provide basic functionality to the application startup process (providing a routing handler, registering dependency container definitions with the DI library, etc.)

App directory

The App directory contains all application code, a layered architecture is being used by default. The app directory has the following sub directories:

Common
This directory contains all code that needs to be re=used throughout each layer inside the application.

Common\Helpers
This directory contains all helper code that needs to be re=used throughout each layer inside the application. It comes with a standard HTTP class that only provides a base for absolute paths.

Presentation
This directory contains all code for the presentation layer of the application. Within this directory, everything that provides functionality for the presentation side of your application should be placed here.

Presentation\Middleware
This directory contains all middleware that the presentation layer needs to use. It comes with a standard middleware class that removes trailing, and duplicate, slashes from the URL.

Config directory

This directory contains all code that provides functionality for the startup process of the entire application. The directory comes with a singular di.php file that provides DIConfig classes. A DIConfig is a class that provides specific data to the dependency container.

App
This directory contains all configuration classes that provide functionality to the application.

App\Autoloading
This directory contains DIConfig classes that provide specific data to the dependency container. A DIConfig class can be used to add definitions to the dependency container, or run a necesary startup process (like loading .env files or setting up a database connection). There are three default DIConfig classes:

SetupDependenciesDIConfig adds generic dependency container definitions to the dependency container.
SetupEnvDIConfig loads the .env file content and adds the variables to the $_ENV superglobal.
SetupRouterDIConfig adds routing capability to the application (this is in a separate DIConfig class since this process should not be edited).

Framework directory

This directory contains all code that provide basic functionality to the application startup process. The framework directory can also include general helpers and utilities, but this only should be done when this is necessary for the startup process, otherwise a Common directory of some sorts should be created inside the ./src/App directory.

Application startup process

It is very important to understand how this application base starts up and configures itself before a route can be registered. The application startup process goes as follows:

Create a dependency container.
Register all dependencies and run all startup processes.
Create a base application class that bootstraps a Slim framework App instance.
Register all middleware with the slim app instance.
Register routes.
Dispatch routes.

If, for whatever reason, the dependency container needs to be accessed for setting up something like an ORM, the getDependencyContainer() function runs step 1 and 2 of the startup process. This function can be called as soon as ./src/bootstrap.php is included.

IMPORTANT: It is not possible to access the dependency container during steps 1 and 2. Do not call the getDependencyContainer() multiple times.

Running the project locally

If the php command can be accessed from within a terminal or CLI, it can be used to run the project locally. For this the following two commands can be issued from the root directory:

$ cd public
$ php -S 127.0.0.1:8080

The first command changes the current directory to the public directory. This is the webserver root of the project and contains the entrypoint to the application.

The second command starts up a local php development server. A neat feature of this server is that it redirects everything back to an index.php file when there are no other available/matching files. If an actual webserver is needed, it is recommended to look at the docker section of this README file.

Running the project in docker

This project base comes with a preconfigured Dockerfile that is placed in the root directory. This file creates an image that uses apache as its webserver. The apache configuration file can be found in the config folder that is also placed in the root directory.

Build image

Before you can run the docker container, you first need to build the image:

$ docker build ./ -t YOUR_IMAGE_NAME_HERE

Start container

Once you an image, you can run it as follows:

$ docker run -it -p 127.0.0.1:8080:80 -td YOUR_IMAGE_NAME_HERE

Note: the command above starts this app on the following URL: 127.0.0.1:8080

Stop container

Once the container is running, you can stop it with the following command:

$ docker stop <container_name>

Note: the container name can be found by running the following command:

$ docker ps

Remove container

Once the container is stopped, remove it with the following command:

$ docker rm <container_name>

Static code analysis

PHP insights is used, and configured, to provide a static code analysis report of the application source code.

Running the tool

$ ./vendor/bin/phpinsights.bat

Receive a detailed report for your written source code

$ ./vendor/bin/phpinsights.bat analyse -v

Configuring rules

PHP insights's analysis rules can be configured through the phpinsights.php file inside the root directory.

Testing

PHP unit has been set up and configured with two testing suites: unit and integration. The configuration file (phpunit.xml) can be found in the root directory.

Run unit test suite

$ ./vendor/bin/phpunit --configuration phpunit.xml --testsuite unit

Run integration test suite

$ ./vendor/bin/phpunit --configuration phpunit.xml --testsuite integration
