PHP SERVERLESS FRAMEWORK

The first and fully functional PHP framework built exclusively for serverless. Support for IBM Cloud Functions

FEATURES

• Easy to learn and start. All required is in this README file.
• Fully automated and extendable via RoboFile (learn more).
• Powerful and super fast router (learn more).
• Lean database library (learn more). Eloquent optional.
• Lean template engine (learn more). Blade optional.
• Lean testing framework (learn more). PhpUnit optional.
• Uses tested serverless deployment framework (learn more)

INSTALLATION

1. Step 1

composer create-project --prefer-dist sinevia/php-serverless .

2. Step 2

vendor/bin/robo init

AFTER INSTALLATION

• Delete the phpunit.xml file, if you are not going to use PHPUnit for testing
• Change the settings in /app/config (serverless function name, etc)
• Change the settings in /env.php (not required usually)

WORKFLOW

Four environments are specified and available out of the box - local, testing, staging, live.

1. Local. All development is done on local - (local)
2. Testing. Automatic tests are run in testing - (testing)
3. Staging. For user and manual testing depoy to staging - (staging)
4. Live. For real live usage deploy to live - (live)

DEVELOPMENT

To start working on the project run the built in PHP server:

php -S localhost:32222

or using the helper function

vendor/bin/robo serve

Then open in browser: http://localhost:32222/

or using the helper function

vendor/bin/robo open local

DATABASE

To run migrations for each environment:

vendor/bin/robo migrate local

vendor/bin/robo migrate staging

vendor/bin/robo migrate live

DEPLOYMENT

The deployment will run your tests, and will continue only if your tests are successful

To deploy to your staging function

vendor/bin/robo deploy staging

To deploy to your live function

vendor/bin/robo deploy live

HELPER FUNCTIONS

A RoboFile exists with automated functionality.

• Run database migrations on local

vendor/bin/robo migrate local

• Run database migrations on staging

vendor/bin/robo migrate local

• Run database migrations on live

vendor/bin/robo migrate live

• Serve the site for development

vendor/bin/robo serve

• Open local/dev url from terminal

vendor/bin/robo open local

• Open staging url from terminal

vendor/bin/robo open staging

• Open live url from terminal

vendor/bin/robo open live

• Deploy to staging

vendor/bin/robo deploy staging

• Deploy to live

vendor/bin/robo deploy live

TESTING

Two testing frameworks supported out of the box:

1. Testify.php - very lean and straghtforward to work with (preferred, and preinstaled)
2. PHPUnit - more mature, but heavy weight with many dependencies

To decide which modify the setting in the RoboFile.

Testing with Testify.php

Testify is a small PHP testing library with no extenal dependencies: https://github.com/BafS/Testify.php

Place your tests in /tests/test.php

To run the tests

php tests/test.php

or

vendor/bin/robo test

Testing with PHPUnit

PHPUnit is a huge PHP testing library. Beware it will come with lots of composer dependencies: https://phpunit.de/

To install the framework with all the dependencies

composer require --dev phpunit/phpunit

Place your settigs in /phpunit.xml. Place your tests in /tests

To run the tests

vendor/bin/phpunit

or

vendor/bin/robo test

SERVING STATIC FILES

Multiple options

Local CSS and JavaScript files are best to be served minified inline. Helper functions are added

<?php echo joinCss(['/css/main.css','/css/secondary.css']); ?>

Small images (i.e. favicon) serve inline as data.

<img src="<?php echo image2DataUri('/public/img/avatar.png'); ?>" />

To serve static files separately place them in the public directory.

/public/css/main.css

For remote static files use CDN, S3 or other storage.

FUNCTIONS

Functions are defined in file /app/functions.php. Feel free to change or remove.

basePath($path = '')

Returns the top most (root, base) path of the application

baseUrl($path = '')

Returns the top most (root, base) URL of the application

db()

Returns a database instance

env($key, $default = '')

Returns an env variable from OPEN WHISK

htmlFormatPriceWithCurrencySymbol($amount, $currency)

image2DataUri($imagePath)

Converts an image path to data URI

isGet

Checks if this is a GET request

isPost

Checks if this is a POST request

joinCss($styles, $options = [])

Joins multiple CSS files, and optionally minifies them

joinJs($scripts, $options = [])

Joins multiple JavaScript files, and optionally minifies them

redirect($url)

Redirects to the specified URL

req($name, $default = null, $functions = [])

Returns the requested $_REQUEST name-value pair if it exists

sess($name, $default = null, $functions = [], $options = [])

Returns the requested $_SESSION name-value pair if it exists

once($name, $default = null, $functions = [], $options = [])

Returns a once value if it exists in $_SESSION. After the value is returned, it is deleted

function reqOrSess($name, $default = null, $functions = [])

ui($view, $vars = array(), $options = array())

Renders a template from app/views. If no extension is specified .phtml is added

view($view, $data)

Renders a Blade template from /views. A /cache folder is required. If using Eloquent for data management this function will clash, delete it, or rename it i.e. to uiBlade($view, $data).

To use the view function you must install Blade:

composer require jenssegers/blade
