ServerGrove Blog:
New Symfony installer the fastest way to start your Symfony project
March 27, 2015 @ 12:13:42

The ServerGrove blog has a new post today introducing the new Symfony Installer, a tool that can make getting started with a Symfony2 application quick and easy.

Yesterday, the Symfony team introduced the new Symfony installer. Its main goal is to help developers to create Symfony projects faster. Until now, installing Symfony to start a new project required a few steps. [...] The installer tries to do this in one step. It downloads a compressed file with all the code, including the vendors directory, so you don't need anything else to run Symfony for the first time.

The post shows you how to install the installer via a curl call to fetch the executable. They show how to use it to create a new project, making a demo project and the resulting application and web interface for the demo. They also mention some of the future work that's planned for the installer including HTTPS support and caching improvements. The post finishes up with a quick mention of the code "under the hood" using the Symfony console component.

Working with the PayPal API
March 27, 2015 @ 09:57:34

PHPBuilder.com has posted a tutorial showing you how to interact with the PayPal API via your PHP application using their own PHP-SDK.

PayPal recently introduced a new RESTful API that is more convenient and more powerful than the previous version. In this article, I will show you how to integrate your PHP application with the new PayPal API.

They start with a summary of the PayPal API and how to get the SDK loaded and ready to use (either through Composer or manually). The tutorial walks you through the authorization process (OAuth) and the code you'll need to make it happen. They also show you how to create transaction (including currency type and description) after the items have been submitted. There's also some code showing you how to get the current status of the payment once it has been submitted.

Scotch.io:
Build a Time Tracker with Laravel 5 and AngularJS - Part 1
March 27, 2015 @ 08:49:57

On the Scotch.io site there's a new tutorial showing you how to build a time tracking application with a combination of Laravel and AngularJS. This is the first part of a new series and focuses on the basic principles and getting some of the first parts of the application up and running.

Laravel and AngularJS work great together, but it can be a little tricky to get going at first, especially if you are new to the frameworks. In a previous article, Chris showed you how to make a Single Page Comment App with Laravel and Angular. This tutorial will again bring the two frameworks together as we build out a simple time tracking application.

We'll be going into a lot of detail in this tutorial, so to make things manageable it has been broken into two parts. The first part will focus on getting the front-end setup with AngularJS and the second part on getting the backend setup with Laravel 5.

He starts with an overall look at the application and what functionality it will have. From there he walks you through:

  • Setting up the folder structure
  • Installing dependencies
  • Creating Javascript files
  • Setting up the view
  • Adding extra styling
  • Fetching the time data

He makes use of the Moment.js library to perform some of the time calculations for the difference and total time elapsed. He ends the post by tying up some loose ends with the controller and updating the view with the new calculated time values.

Writing a webserver in pure PHP - Tutorial
March 26, 2015 @ 11:27:42

On the Clancats.com blog there's a recent post showing how to create a web server in pure PHP, an interesting experiment but definitely not recommended for any kind of higher load situation.

Well, this is pretty useless, but it is possible. But again its pretty.. uesless. This tutorial will hopefully help you to better understand how a simple webserver could work and that it's no problem writing one in PHP. But again using this in production would be trying to eat a soup with a fork. So just, .... just don't. Let me shortly explain why this is not a that good idea.

PHP is a scripting language that simply is not really designed for such tasks. A webserver is a long running process which PHP is not made for. Also PHP does not natively support threading ( pthreads ), which will make developing a good performing webserver a really hard task.

He walks you through all the code needed to create the web server (also available on GitHub) by making:

  • A "server" that does the listening for incoming and sends outgoing requests
  • A request object that parses the incoming request and makes header and body content available
  • A response object that allows for the setting of response codes, body content and headers
  • Exception handling for problems encountered during the request/response process

The full code is provided during the process along with explanations of what each part does. There's also a basic introduction to what a typical web server is and how the process of request/response usually flows.

DigitalOcean Community Blog:
How To Set Up a Two Node LEPP Stack on CentOS 7
March 25, 2015 @ 11:52:30

On the DigitalOcean community blog they've posted a guide to setting up a LEPP server (Linux, Nginx, PHP and PostgreSQL) on a CentOS 7 instance (not specific to their own platform either, can be applied anywhere).

In this tutorial, we will create a simple web application in a two-tier architecture. Our base operating system for both nodes will be CentOS 7. The site will be powered by an Nginx web server running PHP code that talks to a PostgreSQL database. Instead of adopting a "top-down" approach seen in other LAMP or LEMP tutorials, we will use a "ground-up" approach: we will create a database tier first, then the web server and then see how the web server can connect to the database. We will call this configuration a LEPP (Linux, Nginx, PHP, PostgreSQL) stack.

They create a two-tier setup that involves the use of two CentOS systems (with examples from their own hosting options) and walk you through:

  • Installing PostgreSQL
  • Configuring PostgreSQL
  • Updating the Database Server Firewall
  • Creating and Populating the Database
  • Installing Nginx
  • Updating the Web Server Firewall
  • Configuring Nginx
  • Installing PHP
  • Configuring PHP
  • Creating the Web Application

It seems like a lot of steps but all of the necessary commands and configuration updates are included in each step so it's basically a copy and paste kind of walk-through.

Programming With Yii2 Integrating User Registration
March 24, 2015 @ 12:27:16

NetTuts.com has posted the next part in their "Programming with Yii2" series today with this tutorial showing you how to integrate user registration into your sample application.

This is part four of a series on Yii2. In Programming With Yii2: Getting Started, we set up Yii2 locally, built a Hello World application, set up a remote server, and used Github to deploy our code. In part two, we learned about Yii's implementation of its Model View Controller architecture and how to build web pages and forms that collect and validate data. In part three, we learned about working with databases and ActiveRecord. In this tutorial, we'll walk you through integrating a popular user registration plugin.

They walk you through the use of the Yii2-User extension to provide the user handling functionality. The tutorial shows you how to get it installed (via Composer), run its database migrations to create the needed tables and where to update the configuration files to pull the plugin into the execution. They also help you set up SwiftMailer (what it uses to send its emails) and then gets into the integration of the registration with the application with a signup page.

Paul Jones has a new post to his site showing how to merge one of the components of the Aura framework with the templating library Plates, a part of the The League of Extraordinary PHP Packages. In this post he shows how to integrate the Plates rendering engine into the Aura.Html component for use as a view layer.

Aura has its own native PHP template package, Aura.View, a direct descendant of Savant and Solar_View, as well as a cousin to Zend_View. The v1 Aura.View package used to include a helper system. Once we realized that there was no reason to tie the helper system directly to the view system, we released the helpers as a standalone Aura.Html package. This means the helpers can be used in any PHP presentation code, framework-based or otherwise.

Plates lets you register functions against its own internal handling, referencing the different elements to be rendered. He includes a code example showing this integration and how they look used in a Plates template.

SitePoint PHP Blog:
User Authentication in Symfony2 with UserApp.io
March 19, 2015 @ 09:18:18

On the SitePoint PHP blog Daniel Sipose has written up a tutorial showing you how to use the UserApp.io service to authenticate users for your Symfony2 applications.

UserApp.io is a handy user management tool and API. It provides a web interface to deal with user accounts (and the many features this involves) and an API to hook them into your own web application. The purpose of this service is to make it easier and safer to manage user authentication by not having to worry about that on your own server. It has SDKs and various wrappers for many programming languages and frameworks and the price is affordable. Yes, it comes with a price but you can get started freely with quite a lot of things to play around with.

He makes use of this library (his own creation) and the UserApp.io SDK to hook into Symfony2's own Security component authentication handling. He starts by explaining some of the classes he'll be creating including the form authenticator, a user provider, the logout handler and an custom exception. The full code is included for each as well as the changes you'll need to make to the YAML configuration to hook it all together.

Design Patterns The Command Pattern
March 17, 2015 @ 12:42:22

NetTuts.com continues their series covering the basics of design patterns (in PHP) with a new article about the Command design pattern. This pattern is particularly useful for executing self-contained "commands" without other interaction.

In this article, we will be going through the command design pattern. As the name says, in this pattern we will be dealing with executing various commands. [...] Basically a pattern has numerous elements involved, which are as below. In the next section, we will be exploring each element with a code example. I will be taking the example of radio actions-very basic actions would be turning the radio on or off. So let's dive into each element.

Using the illustration of the radio, they go through the creation of the classes for the controls (on/off) and the two matching commands. The invoker is then told to execute the "turn off" command on the radio control object passed in. This sounds a little confusing but the code included in the article makes it clear how this implementation of the command is structured.

How to Use GitHub's API with PHP
March 17, 2015 @ 10:11:39

The SitePoint PHP blog has a new tutorial posted showing you how to interact with the GitHub API via PHP thanks to the KnpLabs library to create a simple automation system to perform some simple tasks.

Github is one of the best ways to share code and collaborate. In this article, we are going to learn how to consume their API and how we can use it to accomplish some of our daily tasks. We are going to explore some of the daily tasks that can be accomplished through the Github API and build a small app using Laravel to illustrate the use cases. You can check the final result on Github.

They walk you through the setup of an application on the GitHub side and how to configure the related settings in your Laravel application. He shows how to bind the GitHub library to the app, set up some sample routes and build out controllers to:

  • List repositories
  • View repository content
  • Editing files
  • Viewing commits

Each item includes the code you'll need to make it happen, an example of the output you'll get from the API and how to use the data on your side in your views.
