Creating Real Time Applications with PHP and WebSockets
July 29, 2014 @ 12:13:07

On PHPBuilder.com today there's a new tutorial introducing you to the combination of PHP and WebSockets to make real-time requests to fetch data in your application.

This article will explore the main PHP libraries used to create real time, bi-directional applications between clients and servers over WebSockets. WebSocket is full-duplex client/server communication over TCP. It is also a new feature available in browsers as a part of the HTML5 specs that allows JavaScript clients to open bi-directional socket connections to a server. [...] WebSocket connections are basically TCP socket connections that following the WebSocket rules to communicate. The WebSocket Protocol is an independent TCP-based protocol.

They introduce some of the basic concepts behind WebSockets (including an example URL) and show how to use the PHPWebSockets library to handle some sample requests. They also include some basic JavaScript to make the request to the backend PHP script and send or fetch content on the server. They also show you how to implement a simple chat server using a few other libraries like Ratchet, Elephpant.io and Socket.io.

Expert Developer:
Install PHP CodeSniffer on Windows Machine
July 29, 2014 @ 10:33:45

On the Expert Developer site there's a new tutorial showing you how to get the PHP CodeSniffer tool up and working on a Windows installation. PHP CodeSniffer provides functionality to enforce standards and best practices in your application's development (providing code quality).

In this article we will focus on improving Code Quality. Very first step towards improving code quality is to maintain coding standards across developers. [...] Here we will talk about PHP CodeSniffer, which help us to maintain coding standard across multiple developer. Dealing with CodeSniffer is much easier: create rule set, validate your file against your rule set and get the result immediately. It will immediately show how many mistakes you have made in terms of following coding standards and eventually all developer will start coding as per coding standards you have defined.

There's two main parts to the article: first is getting PEAR installed (a package manager for PHP) and then using it to install CodeSniffer. Complete instructions and commands are included as well as a few screenshots along the way.

Sameer Borate:
Downloading Gmail attachments in PHP - an update
July 29, 2014 @ 09:37:40

Sameer Borate has posted an update to a previous post of his about downloading attachments in PHP. In this new post he updates the script to remove any other dependencies other than the IMAP PHP extension.

As mentioned in the earlier post, automatically extracting attachments from Gmail can be important for reasons where you need to process the attached files periodically with a CRON job or need to process the files programmatically. Also it can be useful for automatically archiving important attachments. [The code in this post] is a simple proof-of-concept plain PHP code, devoid of any object-oriented features that extracts attachments from your Gmail account.

The example code makes a request to the Gmail IMAP servers with the given username and password, grabs the first set of emails, parses their attachments to pull them down to the local host. He also includes some searching capability to locate ones only matching certain criteria. A list of the allowed search keywords is also included. He finishes the post with a look at using READONLY mode and fetching the email headers.

SitePoint PHP Blog:
Best Practices REST API from Scratch - Implementation
July 24, 2014 @ 13:11:22

PHPMaster.com has posted the second part of their best practices in REST APIs series with this new post focusing more on the implementation part of things.

We ended the first part of this tutorial with all the basic layers of our API in place. We have our server setup, authentication system, JSON input/output, error management and a couple of dummy routes. But, most importantly, we wrote the README file that defines resources and actions. Now it's time to deal with these resources.

They move on and add more functionality for creating (POST) and updating (PUT/PATCH) contacts in the system. They also show how to list contacts and add in some search handling allowing for sorting and returning only certain data. There's also some code for pagination handling, locating a single contact record, basic caching and simple rate limiting.

Master Zend Framework:
Configuring the ServiceManager with Abstract Factories
July 23, 2014 @ 13:41:10

On the Master Zend Framework site today Matthew Setter has a new post covering the configuring of the service manager using abstract factories.

One of the best features about Zend Framework 2 is undoubtedly the ServiceManager; because it makes it almost painless to configure and retrieve services in a consistent and predictable manner, anywhere in your application, at any time. [...] But the catch is, there's quite a bit to learn if you want to use it properly. As well as that, there's quite a number of ways to use it.

He walks you through some of the pros and cons of the various ways to work with the ServiceManager and where the factories fit in. He takes a bit of time to introduce the concepts behind abstract factories and how to define them in a Zend Framework v2 application. He finishes out the post with a more practical, working example using the interfaces provided to get a "MyUserTable" service.

SitePoint Web Foundations Blog:
Quick Tip Install Zend Server 7 on an Ubuntu 14.04 Vagrant Box
July 22, 2014 @ 11:14:30

The SitePoint Web Foundations blog has a post from Bruno Skvorc showing how to install Zend Server on Ubuntu 7 set up and configured by Vagrant.

I recently took a look at Zend Server 7, the latest version of the powerful application monitor/manager suite. This quick tip will show you how to get it installed on a Vagrant box so you too can experiment with its features.

The process is made up of four (well, five...one is optional) steps making it pretty easy to try out:

  • Install Prerequisites
  • Clone and Boot
  • Download and Run Installer
  • Fix Log Permissions
  • Deploy an Application (the optional one)

He includes the code updates you'll need to make and some screenshots along the way to be sure you're on the right track.

SitePoint PHP Blog:
Best Practices REST API from Scratch - Introduction
July 22, 2014 @ 09:39:12

The SitePoint PHP blog has posted the second part of their series looking at building up a REST API "from scratch". In this latest post Vita Tardia introduces some of the basic topics and the best practices that are around their use.

The current internet ecosystem has literally been invaded by APIs, and for good reasons. By using third party APIs in your products or services, you have access to a ton of useful features - such as authentication or storage services - that can benefit both you and your users. By exposing your own API, your application becomes "part of the mix" and will be used in ways you've never thought before… if you do it the right way, obviously. In this two part series I'll show you how to create a RESTful API layer for your PHP applications, using a collection of real world best practices.

He talks about how a REST API is a "user interface for developers" and the actions the different verbs could take on the same endpoints (PUT, POST, GET, etc). He uses the Slim framework in his examples and helps you get an instance all set up and working. He includes a bit about getting SSL/HTTPS up and running for all requests to the site too. From there he gets into the bootstrapping of the application and the first version of controller handling. He also includes code examples touching on JSON handling, authentication and good error handling.

php[architect]:
Sending HTML Emails with Drupal 7, Webform, and Mandrill
July 21, 2014 @ 12:42:45

The php[architect] site has a new tutorial posted giving you a step by step guide to sending HTML email with the combination of Drupal 7, Webform and Mandrill (the mail service by Mailchimp).

By default, Drupal is configured to send out plain text emails. For many developers, plain text email is sufficient and preferable to HTML email. HTML email is still, in this day and age, not guaranteed to render the same across email clients, more likely to be labeled as spam, and requires a significant amount of testing to make sure it works. Still, a minimally styled HTML message can be easier for recipients to read and help reinforce your brand/design (if you don't depend on images to do so). In this article, we'll look at the modules to install and configure to enable HTML emails and, specifically, how to change the default Webform email template to send submissions as HTML.

The tutorial comes in four different sections, each with plenty of description and some code to make it happen:

  • Set up your site to send email
  • Allow outgoing email to use HTML
  • Formatting Outgoing Email
  • Send Webform Submission as HTML Emails

SitePoint PHP Blog:
Social Network Authentication Twitter and Facebook
July 21, 2014 @ 11:32:12

The SitePoint PHP blog continues their series of tutorials showing how to authentication your users against various social networks. In the previous post they covered connecting to Google+ and in this latest post they move on to two other popular social networks: Facebook and Twitter.

In the previous parts of this series, we created our initial interfaces, set up our Google+ login functionality and talked about how we can merge our accounts together. In this article, we will integrate Twitter and Facebook within our application. You will see a lot of similarities with the Google+ article, so if you could follow that one easily, you won't have much trouble with this one. If you haven't read that article yet, I suggest you read it first before continuing this article.

He starts off with the Twitter authentication, creating a new "SocialLogin" object type for it and defining the three required properties it needs to connect. Code is included to make the OAuth connection, pass along the callback URL and forward on the user to the Twitter site for approval. Code is also included to store the data about the Twitter user in your application. Next up is Facebook. The connection is very similar to the others with only a slight difference in the data that's required. You can find the full code for the tutorial so far in this Github repository.
