Getting Started With Silex Micro-Framework On Cloud Hosting
Sep 19, 2016 @ 11:54:34

On the CloudWays blog they've posted a tutorial that introduces you to the Silex framework, a product from SensioLabs of Symfony fame and using it on a cloud hosting platform (their own).

Extensibility is one of the main aims of web app development projects. However, there are times when you need to get things up and running as soon as possible and with minimum time dedicated to coding. This is where micro-framework s really outshine the competition. There is a long list of these frameworks including Silex, Slim, Lumen, etc. These are ideal for developing small-scale applications with clean code and user defined directory structures.

In this tutorial I am going to explain how to install Silex, its operation, directory structure, Routings and HTTP Requests. Silex is a micro-framework written in Symfony and inspired by Sinatra, a DSL for quickly creating web applications in Ruby with minimal effort.

They start by helping you get the CloudWays instance up and running with their "PHPStack" setup. Once created they show how to get to a command prompt, make the public HTML directory and use Composer to install Silex and Twig (for templating). The tutorial then briefly covers the directory structure for the site and the code to create the Silex application instance. They define some of the basic routing (to work with book data) and show the handling for sending feedback submitted via a simple page. The remainder of the tutorial shows the use of different features of Silex including: providers, middleware, before/after handlers and defining controllers as classes.

Understanding the Laravel Service Container
Sep 13, 2016 @ 12:56:04

The Dotdev.co blog has posted a tutorial for the Laravel users out there with the goal of helping you understand the Laravel service container, a key part of the framework's functionality and an extensible feature you can adapt to some of your own needs.

Learning how to build an application with Laravel is not just about learning to use the different classes and components within the framework, it is not about remembering all artisan commands or remembering all helper functions (we have Google for that). Learning to code with Laravel is learning the philosophy of Laravel, its elegance and its beautiful syntax. I personally feel it is an art and a craft (its not a coincidence that Laravel developers are sometimes referred to as Web artisans). This is true for any other framework as well.

A major part of Laravel’s philosophy is the Service Container or IoC container. As a Laravel developer, understanding and using the Service Container properly is a crucial part in mastering your craft, as it is the core of any Laravel application.

The post starts with some of the basics about the container and how objects/instances are bound to it. They give an example of binding a FooService class in the "register" methods of providers. A code example is also included showing how to use the service you previously bound. There's also a description of binding interfaces in the IoC, making it easier for custom classes to resolve interfaces when they're implemented. The post wraps up with a bit covering the resolving of dependencies and the code you'll need to set them up.

Master Zend Framework:
How To Build a Local Development Environment Using Docker
Sep 02, 2016 @ 11:57:05

The Master Zend Framework site has posted a tutorial helping you create a Docker-based development environment complete with PHP, MySQL and Apache working happily together.

Why in this modern day and age is setting up a development environment still such a complicated process? [...] Why is it still so hard to get one setup that works, that does what you need, and that matches the deployment environment’s of testing, staging, production and so on?

[...] By now our development environments have grown quite sophisticated. But the overhead of both building and maintaining them has increased significantly also. Wouldn’t it be easy if we could set them up, but with only a small investment of time and effort? I think you know where I might be heading with this. You can. Yes, that’s right, you can. Ever heard of Docker?

He then starts in on introducing Docker (for those not already familiar) and how it differs from a VirtualBox/Vagrant setup that's already become quite popular. He talks about "containers" and the role they play as well as an overview of the environment he's going to show you how to create. He then helps you get Docker installed, explains how the containers will work together and provides the Docker YAML configuration for each of them. The docker-compose command is then used to bring the environment up, downloading the containers as needed. The final result of his setup is a set of containers running together to serve up a Zend Framework Skeleton Application.

How To Create Simple Rest API In Symfony 3.1
Aug 30, 2016 @ 12:59:10

The Cloudways blog has posted a new tutorial helping you get up and running quickly with a simple REST API written using the Symfony framework. In the article they not only explain how to create the API but also include a bit of REST theory for those not completely familiar with the terms and functionality involved.

Symfony is fast becoming the favourite framework among developers for rapid application development. And despite releasing Symfony 3.1 and 3.2 in the previous quarter, they are still introducing many changes and upgrades. If you’re still using the previous versions, you must upgrade Symfony Framework to the latest and stable version 3.1.

Yes! We know that Symfony is one of the best frameworks to develop rest API, so in this article we will make simple rest API in Symfony 3.1. I am assuming that you’ve already setup PHPstack application on Cloudways with Symfony installed, but if you haven’t, follow this installation guide.

They briefly talk about the REST HTTP verb types and what kind of actions they relate to. With that defined the tutorial then gets into the requirements including the installation of two bundles: JMSSerializerBundle and NelmioCorsBundle. From there examples of configuration changes, commands to make users and execute migrations on the local database are included. With this system set up they include sample code for each HTTP verb type letting you perform the actions on the User entity (create, read, update and delete).

Easy and Fast Emails with Laravel 5.3 Mailables
Aug 26, 2016 @ 11:32:01

The Scotch.io blog has posted another Laravel-related tutorial, this time focusing in on "mailables", a new feature in the latest release of Laravel (v5.3) that makes sending emails simpler.

Laravel 5.3 has just been released and there are a ton of great new features. One of the major improvements is in how you send mail in your applications.

They start with a look at how you might send emails in previous versions of the Laravel framework using the Mail::send method with a set of options and a callback. The tutorial then moves on to v5.3 and introduces the idea behind "mailables" and some simple examples. They show how to create a custom mailable-based class and the resulting code. They walk you through how to pass data into the email views, changing up the mailer configuration, sending extra parameters and sending the emails. They also include information about email queueing using Laravel's built-in queuing functionality.

Matt Trask:
Looking at Ramsey UUID
Aug 24, 2016 @ 09:16:56

Matt Trask has put together a new post spotlighting a handy library that's widely used across the PHP ecosystem for generating UUIDs: ramsey/uuid.

Welcome to the first installment in my 2113918230981 part series, "Better know a Package!". Tonight's package: the famous/infamous Uuid package that that taught us all what Ramsey is in Scottish, Rhumsaa. Created to give PHP a library to generate Universal Unique Identifiers, this library has been a stallwort in the community. Ben Ramsey created it first under the Rhumsaa namesapce before moving it to the Ramsey namespace, saving us all from learning more Scottish then we needed to ever learn.

[...] A UUID, or Universally Unique Identifier, will generate a 128 bite unique key in different series based on the version you asked for. RFC-4122 dictates how Uuids should be generated, and recommends 4 types.

Matt then goes on to describe each of the different UUID types and provides some code examples as illustration:

  • Version 1: Time and MAC addressed based Uuid
  • Version 2: DCE-based
  • Version 3: UUIDs based on a namespace and then it is MD5 hashed
  • Version 4: Random generation (based on the output of random_bytes

He also includes examples of the UUIDs output by each method (not much difference there as the structure of the resulting UUID is all the same).

SitePoint PHP Blog:
Framework-Agnostic PHP Cronjobs Made Easy with Crunz!
Aug 23, 2016 @ 13:36:59

The SitePoint PHP Blog has a new tutorial posted from author Reza Lavaryan showing you how to use the Crunz package to make cronjobs a bit simpler in a more framework-agnostic way.

In this article, we’re going to learn about a relatively new job scheduling library named Crunz. Crunz is a framework-agnostic library inspired by Laravel’s Task Scheduler, but improved in many ways. [...] Before getting started, you should have a firm grasp of cronjobs, so please read our in-depth walkthrough if you’re unfamiliar with how they work.

The tutorial then starts in on the code, getting the library installed and setting up a basic task example. The "task" files are sets of cron-formatted commands that are read and executed much like the cron daemon would on a Unix-based system. Example code for a task and command are included. They also talk about the "frequency" settings allowed by the library and the helper methods to make creating them simpler. The post also includes details about task lifetime, running conditions, configuration and parallelism (among other topics).

Stovepipe Systems:
Symfony Security Roles vs. Voters
Aug 22, 2016 @ 10:08:28

On the Stovepipe Systems blog author Iltar van der Berg has retuned with a continuation of his series on Symfony security basics with this new post covering voters and roles.

In my previous blog post I've explained the basics of authentication, authorization and how this is dealt with in Symfony. Due to the size of the post, I've left out several important topics such as roles and voters; Both an equally important part of authentication and authorization. A common misconception is that roles should be used to check permissions. In fact, they should definitely not be used to check permissions!

He goes on to explain where "roles" come into the process of authentication (not authorization) and how they describe something about the user of the system. With that defined he moves on to the "voters": functionality that "vote" on attributes related to the user/request/resource/etc. and return a pass or fail decision based on their logic. He explains why voters are probably more what most developers are looking for and some reasons to use them over roles. He then ends the post showing how to create your own custom voter and configure it into your application.

A Pokemon Crash Course on CouchDB
Aug 12, 2016 @ 10:02:56

The SitePoint PHP blog has a new tutorial posted giving you a "Pokemon Crash Course" on CouchDB, the popular NoSQL database. The "Pokemon" part comes in related to the data the tutorial uses to show you common operations and the use of a PHP interface to perform them.

In this tutorial, we’ll walk through working with CouchDB, a NoSQL database from Apache. This tutorial will focus more on the practical side, so we won’t cover what CouchDB is good for, how to install it, why use it, etc. We’ll focus on how to perform database operations through CouchDB’s HTTP API and how to work with it in PHP, laying the foundation for future, more complex posts.

The article is then broken up into different sections by operation, starting with the use of the CouchDB database via a console then via PHP:

  • Creating a Database
  • Talking to the HTTP API
  • Creating New Documents
  • Bulk Insert
  • Retrieving Documents
  • Updating Documents
  • Working with PHP

Each section includes code snippets and (where relevant) screenshots of the results to help you ensure you're on the right track.

Testing Your Drupal Site with Behat
Aug 11, 2016 @ 11:32:45

On the php[architect] site there's a new tutorial posted from Oscar Merida about testing Drupal sites with Behat, a popular PHP-based "Behavior Driven Development" testing tool to help ensure your application is performing correctly from the outside.

If automated testing is not already part of your development workflow, then it’s time to get started. Testing helps reduce uncertainty by ensuring that new features you add to your application do not break older features. Having confidence that your not breaking existing functionality reduces time spent hunting bugs or getting reports from clients by catching them earlier.

Unfortunately, testing still does not get the time and attention it needs when you’re under pressure to make a deadline or release a feature your clients have been asking for. [...] After reading all the theory, I only recently took the plunge myself. In this post, I’ll show you how to use Behat to test that your Drupal site is working properly.

He starts by listing some of the requirements you'll need to get started (packages installed via Composer) including the installation of a Drupal specific plugin to make testing these sites easier. From there he shows how to configure the Behat tool and write a simple feature to test the visiting of a certain page and looking for matching results. He also includes tips about testing with user authentication, using custom contexts and Selenium integration.
