Rabbit behind the scenes
October 01, 2014 @ 12:19:53

In a recent post to his site Piotr Pasich shares an article about using a rabbit behind the scenes - making use of the RabbitMQ queuing system for behind the scenes work in your PHP applications.

In PHP business logic is usually put right in action's method or just behind it. Hence, every little piece of delaying and long-running code will be processed with a request. The problem is almost undetectable if a user sends an e-mail but with more complex actions it may take a little bit longer than preferred. [...] In this article I would like to make an attempt to present a solution to the very annoying everyday problem that probably many programmers came across in their organisations - deadlocks in databases caused by a vast number of requests in relatively short time. The main aim of this text is to introduce RabbitMQ, which I value as a very functional and practical message broker, to help you solve the queuing problems and decrease the amount of work you would otherwise have to spend on it.

He talks about why message brokers are even needed and how to pick the right one for your project. Then he gets into the "in practice" part of the article, showing the use of RabbitMQ through PHP to save various data to a database when a user is presented with an advertisement. He shows how to create both the producer and consumer objects, making interaction with the queue simpler. His examples are all using the php-amqplib by Alvaro Videla.

Creating Twitter Apps in PHP
September 29, 2014 @ 09:28:42

Sameer Borate has a post today showing how you can create a simple Twitter application in PHP making use of their REST API and the twitter-api-php library.

In this post we will look into accessing Twitter REST API in PHP. This can be useful if you need to post Tweets from your PHP application or anaylze, search Tweets. In the following examples we will use the twitter-api-php PHP wrapper for Twitter v1.1 API. Although there are a few wrappers around, this one I like for its simplicity.

He helps you get the library installed (via Composer) and create an application on the Twitter side at apps.twitter.com. Sample code is included showing how to connect to the API with your credentials, including handling the OAuth authorization piece. From there he shows two examples of action to make on the API: posting a new tweet and searching for new tweets based on a query string.

SitePoint PHP Blog:
Essentials of LDAP with PHP
September 26, 2014 @ 09:07:37

On the SitePoint PHP blog today Matthew Setter has written up a tutorial sharing the essentials of PHP with LDAP. He shows how to connect PHP to this industry standard technology and effectively query, update and delete information.

Ever wanted a simple way to store address book style information and network information actually next to any kind of ordered information? If so, then there's a technology which has been around since 1993, one which despite not having the cool factor of such technologies as Node.js and Go, allows you to do exactly this. It's called LDAP!

He starts off the tutorial by explaining a bit about what LDAP is (and isn't) for those not familiar with it. He covers some of the basic terminology, pointing you other articles if you need more than just his brief overview. Then he helps you get an LDAP server installed locally (using a package manager, apt-get) and how to verify the install is working correctly. From there he shows how to populate a few records and verify they exist. Following this, he gets to the PHP part of things, showing how to use the Zend Framework v2 Zend/Ldap component to access the server, query records and update/delete them easily.

How to Deploy Symfony Apps with Capifony
September 25, 2014 @ 10:55:27

The SitePoint PHP blog has a tutorial today showing you how you can use the popular Capistrano tool to deploy Symfony-based applications. More specifically, it's focused in on one tool, Calpifony, that's a bit more tailored to what a Symfony deployment needs.

Say you have a Symfony application. At some point, you would like to deploy it to your server and show it to the world. Of course, you can do it all manually, but these days you can also choose to use a tool like Capifony. If you have developed Ruby applications in the past, you are perhaps familiar with Capistrano. Capistrano is a tool to deploy your Ruby application to your server. Capifony has been created on top of Capistrano, and is basically a collection of deployment recipes. In this article, we are going to deploy a Symfony application to a server with Capifony.

He starts off with a section giving an overview of how the Capifony tool works and how important the directory structure is. He then guides you through the installation of the tool and configuring your first simple project. He includes an example "deply.rb" configuration and walks through each piece, describing what it does and how to add some additional commands to the list. The post ends with the full updates configuration that makes the connection to the server, downloads a copy of a Git repository and executes Assetic and Bower commands on build.

SitePoint PHP Blog:
What to Expect from Yii 2.0
September 22, 2014 @ 12:32:17

The SitePoint PHP blog has a new post today from Arno Slatius that talks about some of the features coming in Yii 2.0, a PHP-based MVC framework with a target for a stable release coming very soon.

Yii 2.0 was released into beta last April and the goal for a first stable release was set for the middle of 2014. The GitHub issue list has 300 open issues and 2913 closed while I'm writing this and both numbers are still increasing. The progress to the 2.0RC milestone was at 99%. My guess is that the team is close, but we'll probably have to wait just a little bit longer. While we're all waiting, lets take a look at what we can expect by looking at an already available example.

He starts with a "tiny bit of history" about the framework (its origins, the work done on 2.0) and talks about some of the requirements to get it installed and working. He helps you set up a sample project and shows off the Twitter Bootstrap integration, the debug bar and the "Gii" tool that can help generate code automatically (following the conventions of the framework). He finishes off the post with a look at some of the main things that changed in the 2.0 release including moving some method calls to properties, datetime handling, behavior definitions and model/view updates.

Data cleaning in PHP applications
September 22, 2014 @ 09:41:56

Sameer Borate has a new post today showing the use of a "cleaner" library to help sanitize the data input to your application. In this tutorial he introduces you to Mr Clean, an "extendible PHP Data Cleaner".

Scrubbers or data cleaners are an important part of the data transformation process. Whenever you are involved in some data import or export process, data scrubbers can help you clean and standardize your data elements before storing. There are many libraries that help in sanitizing and cleaning data. One such I recently found is mr-clean; it is a extendible PHP Data Cleaner that you can use in your PHP applications to clean heterogeneous data before storing it in your database or other persistent storage like CSV files.

He walks you through the installation (via Composer) and the creation of an instance of the main "cleaner" object. He then provides a few examples of some data scrubbing features it offers:

  • Basic scrubbing (trim, stripping HTML tags, etc)
  • Booleans
  • Filtering HTML
  • Stripping CSS attributes
  • Nullify
  • Null if repeated
  • Strip Phone Number
  • Pre/Post scrubbing handling

He finishes up the post with a look at creating a custom scrubber class, an "only numeric" handler that replaces any character that's not a number in a string with an empty string (removing it).

SitePoint PHP Blog:
Ardent Laravel Models on Steroids
September 19, 2014 @ 11:54:34

In Ardent, an enhancement to the model system in the Laravel framework that allows for easy configuration of validation rules.

One of the (few) things I don't like about Laravel is that you cannot move the validation code from your controller to your models easily. When I write software I like to apply the "fat models, skinny controllers" principle. So, for me, writing the validation code in the controller is not a good thing. To solve this, I'd like to introduce Ardent, a great package for Laravel 4. To be more precise, Ardent presents itself as "Self-validating smart models for Laravel Framework 4's Eloquent ORM." In other words: exactly what we need!

He introduces the library as a part of a test application, a To-Do list that includes user and task handling. He starts with the creation of the base Laravel migrations to build the tables and the code for the two necessary models. He then shows how to install Ardent and put it to use in the controller code, adding validation rules and messages for each property on failure. He also shows how to use the model auto-hydration and hooks to make working with the models even easier. He finishes off the post showing how to set up relations "the Ardent way" using a slightly different format as the usual Laravel handling.

SitePoint PHP Blog:
PHP Streaming and Output Buffering Explained
September 04, 2014 @ 10:17:44

The SitePoint PHP blog has a new performance-related post to the site today from Imran Latif. This new post looks at effective use of output buffering and streaming and explains how it works and some examples of its use.

As a PHP developer, I was wondering whether we can have something similar [to Streaming in Rails] in our favorite language? The answer is yes - we can easily have streaming in PHP applications with little effort, but in order to get this right we have to become familiar with some underlying concepts. In this article, we will see what streaming is, what output_buffering is and how to get our desired result under different webservers (Apache, Nginx) and PHP configurations (CGI, mod_php, FastCGI).

He starts off with a comparison of the two different methods, streaming and output buffering, and how they behave in the output of content. He then gets into some simple examples with PHP with various methods: a simple delay, chunking up output and finally using the actual output buffering handling PHP offers. He also includes an example of streaming content over an Ajax request with a simple test using the sleep function.

PINQ - querify your datasets - introduction
August 21, 2014 @ 09:20:19

The SitePoint PHP blog has posted the first part of a new series they're releasing about querying your data with Pinq. It's a PHP-based query tool that provides a fluent interface for searching and traversing your data. In this first post of the series Taylor Ren introduces you to the library and shows some basic usage.

You may have heard of LINQ (Language-Integrated Query), a "set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic". It provides necessary interfaces and syntax to perform various queries on a given dataset so that operations like filtering, sorting, grouping, aggregating, etc can be performed. PINQ (PHP Integrated Query) is "based off the .NET's Linq, and unifies querying across arrays/iterators and external data sources, in a single readable and concise fluent API".

He talks about normal searching (equals matching) and "faceted searching", narrowing down the results piece by piece until you find what you need. He gives an example with some sample database data and shows the results of a simple query with a price filter and grouped by author. He includes the code to make it happen (inside a simple Silex application) too. He then takes a deeper look at the LINQ queries and how related statements are handled.

Oracle Coherence Blog:
Getting Started With The Coherence Memcached Adaptor (and PHP)
August 20, 2014 @ 10:55:45

As Chris Jones mentions in his latest post to his OTN blog, there's a tutorial that's been posted by David Felcey showing how to get started with Oracle Coherence via the memcached adapter in PHP. Coherence is Oracle's own version of a key/value storage that focuses on performance and scalability.

Coherence 12c (12.1.3) adds support for Memcached clients to directly store data a in Coherence cluster using the Binary Memcached protocol. This post outlines how to configure the Coherence Memcached Adaptor and includes a simple PHP example to show how Memecached clients can connect to a Coherence cluster.

He includes the XML configuration you'll need to create/modify on the Oracle side to make the memcached connections work and explains the different parts. With that in place, he moves on to the PHP example, showing a simple memcached request to store and retrieve a string. It's almost transparent to the PHP user save some of the configuration options required to make it work.
