Git Repository and the Branches

1. Most stable and recent version is at the master branch, previous versions are in the version branches such as v4, v3, v2, and v1.

2. Version branch with the current version such as v5 is used for building up the next release. It's documentation may not be updated frequently and thus reserved for the daring ones.

3. Feature branches such as features/html and features/router are purely for experimentation purpose to try out a feature. They may be merged when ready.

Test Drive

Install this repository to try out the examples.

Make sure PHP 5.4 or above is available on your server. We recommended using the latest version for better performance.

1. Install Composer

Restler uses Composer to manage its dependencies. First, download a copy of composer.phar. It can be kept in your project folder or ideally in usr/local/bin to use it globally for all your projects. If you are on Windows, you can use the composer windows installer instead.

2. Install Restler

Option 1. Using composer create-project

You may install Restler by running the create project command in your terminal. Replace {projectName} with your actual project name. It will create a folder with that name and install Restler.

Note:-

1. If you do not want the additional formats and BDD tools you can include --no-dev to enforce exclusion of dev packages.

2. If you want to try the bleading edge v3 branch or any of the feature branches include 3.x-dev or dev-features/html in the above command

Option 2. Downloading from GitHub

After installing Composer, download the [latest version]() of the Restler framework and extract its contents into a directory on your server. Next, in the root of your Restler project, run the php composer.phar install (or composer install) command to install all the framework's dependencies. This process requires Git to be installed on the server to successfully complete the installation.

If you want to update the Restler framework, you may issue the php composer.phar update command.

Note:- If you are not allowed to install composer and git on your server, you can install and run them on your development machine. The resulting files and folders can be uploaded and used on the server.

3. Configure

Ideally public folder should be mapped as your web root, It is optional, but recommended avoiding exposing unneeded files and folders.

4. Try it out

Try the live examples in your localhost.

You may launch the PHP's built-in server with composer serve command.

5. Run some test

Update the base_url specified in behat.yml and then try the following command

alternatively you can run composer test

This will test the examples against the behaviors expected, for example

All set, Happy RESTling! :)

Quick Start Guide

We have two options to create your own restler api server

1. Most convenient option is using application templates such as Restler Application which has integrations with many packages to help us with the business logic as well. If you choose this option, select a branch in that repository and proceed with the instructions available there.

2. Create a project from scratch so that you have full control over every aspect of your application. If you choose this option, follow along with the steps below.
   • create a folder to hold your project and open it in the terminal.
   • run composer init and follow along to create composer.json
   • when it is asking for dependencies, type restler/framework and ^5 for the version constraint.
   • alternatively, you can leave it blank and create the composer.json first and then run composer require restler/framework:^5

we are using restler/framework instead of luracast/restler to reduce the space required for the package. It is coming from https://github.com/Luracast/Restler-Framework it contains only the contents of src folder here.

Even when you are building from scratch, checking out the application templates will help with folder structure decisions and finding other useful packages.

1. Write API

Create your API classes with all needed public and protected methods

2. Open the Gateway

Create the gateway (public/index.php) as follows

3. Prettify URLs

Enable URL Rewriting

Make sure all the requests go to index.php by enabling URL Rewriting for your website

For example:-

If you are on Apache, you can use an .htaccess file such as

Note:- This requires AllowOverride to be set to All instead of None in the httpd.conf file, and might require some tweaking on some server configurations. Refer to mod_rewrite documentation for more info.

If you are on Nginx, you have to make sure you set the server_name and pass the PHP scripts to fast cgi (PHP-FPM) listening on 127.0.0.1:9000

Note:- This requires PHP, PHP-FPM to be properly installed and configured. Refer to PHP FastCGI example for more info.

4. Customise

Fine tune to suit your needs

Explore the api and try it out by openings explorer/index.html from the web root on your browser

Happy Exploring! :)

Note:- Using eAccelerator can make restler to fail as it removes the comments. More info can be found here

5. Annotate

Restler supports annotations in the form of PHPDoc comments for API fine tuning

They are documented in detail under Annotations

6. Authorize

In order to protect your api, authenticate and allow valid users

7. Start Production

By default Restler runs in debug mode more fine tuned for API developer, by showing detailed error messages and prettifying the api result to human readbale form

By turning on production mode you will gain some performance boost as it will cache the routes (comment parsing happens only once instead of every api call), few other files and avoid giving out debug information

Note:- When production mode is set to true it always uses the cache and does not detect changes and new routes if any. Your continuous integration pipeline or your git hook should delete this file during the deployment process. Alternatively you can pass second parameter to restler constructor to refresh the cache when changes need to be applied.

Change Log

Restler 5

• Semantic versioning to move forward
• Support for PHP 8
• Corrects the source path to be outside the vendor directory
• Adds php development server support with composer serve command.
• Ability to run the tests with composer test command after running the server with composer serve in another window.

Restler 3.0 RC6

What's new

• Adds PassThrough class to serve files outside your web root, including secure downloads
• Adds Explorer class (v1 swagger 1.2 spec, and v2 swagger 2.0 spec) as a potential replacement to Resources class (swagger 1.1 spec)
  • Explorer comes bundled with the html, css, and assets. So that you need not manually download and configure it
  • Explorer combines the parameters that are expected in the request body to create a unique model for swagger
  • Since Restler Explorer comes bundled, you can map to it to your url of choice. For example $restler->addAPIClass("Luracast/Restler/Explorer", 'swagger') maps it to /swagger.
  • Explorer metadata can be easily customized with ExplorerInfo class

Improvements

• Routes class improved to provide a findAll method to list all the routes for a specific version of the API excluding the specified paths and http methods.
• The magic properties utilized by routes when found, ignoring actual properties. This is useful for Dynamic Model classes such as Eloquent.

• Routes now allow @required and @properties to be arrays when the parameter is an object. This helps us to pick and choose the properties for each api method differently. Example {@properties property1,property2,property3} {@required property1,property2} makes an api to only look for 3 properties and 2 of them are required.

• Optimized the Nav class. It now makes use of Routes::findAll(), along with Explorer class

• Restler class has setBaseUrls method to set acceptable base urls that can be set using $_SERVER['HTTP_HOST']. Read this article to understand why. This is useful in the following cases when

  • PHP has trouble detecting the port correctly
  • multiple domains are pointing to the same server
• Restler class now allows overriding the status code by setting $this->restler->responseCode from the api method.

• Improved Forms class to send the embedded properties to emmet template. For example

  Generates the following form

  <form role="form" id="form1" method="POST" ...

  because the emmet template has id in it (see below)

  form[role=form id=$id# name=$name# method=$method# action=$action# enctype=$enctype#]

• Forms class uses embedded properties with @param comments to set html attributes (for example id, accept etc) easily
• FormStyles improved.
• Validator is now initialized by scope so that we can set its properties with @class comment. Example: - @class Validator {@holdException} makes the validator to hold the exceptions instead of throwing
• Improved Form validation with error messages for individual fields.
• Forms example updated to show validation errors with bootstrap based themes.
• CommentParser is now able to parse @property, @property-read, @property-write to support documenting the dynamic properties.
• CommentParser supports short array syntax such as string[], DateTime[]
• Scope adds support for external DI Container of your choice with Scope::$resolver property.
• Renamed String class to Text for PHP 7 support (String is a reserved keyword in php7)
• Flash now implements ArrayAccess so that we can access flash variables just like an array
• composer.json: removed many dependencies from require-dev. Will prompt the developers to install them individually when they need them.
• newrelic support added.
• Memcache support added.
