PHPMaster.com: Understanding the Factory Method Design Pattern

PHPMaster.com: Understanding the Factory Method Design Pattern
On PHPMaster.com today there's a new design pattern-focused that introduces you to using the Factory method to create new objects on the fly.The Factory Method pattern is a design pattern used to define a runtime interface for creating an object. It's called a factory because it creates various types of objects without necessarily knowing what kind of object it creates or how to create it.Code is included showing how to make creating "Product_*" classes as simple as calling a "build()" method with the...

Brian Smithwick's Blog: Software development and the locked box

Brian Smithwick's Blog: Software development and the locked box
In this recent post to his blog Brian Smithwick talks about the "locked box" that developers can sometimes restrict themselves to - getting to comfortable in the tech they already know and not branching out.Jason Austin gave a great presentation at CodeWorks Raleigh recently about cultivating one's passion for software development through side projects -- safe spaces where we can play with new technologies and techniques. The point's well taken: as developers, we're probably putting most of our energy...

Nikic's Blog: How big are PHP arrays (and values) really? (Hint: BIG!)

Nikic's Blog: How big are PHP arrays (and values) really? (Hint: BIG!)
In this recent blog post nikic takes an in-depth look at how large PHP arrays really are - how memory is used in the creation and management of these handy PHP variable types.In this post I want to investigate the memory usage of PHP arrays (and values in general) using the following script as an example, which creates 100000 unique integer array elements and measures the resulting memory usage. [...] How much would you expect it to be? [...] Now try and run the above code. You can do it online if you...

On Error Handling and Closures

The error suppression operator in PHP ("@") is often seen as a necessary evil. Many, many low-level function will return a value indicating an error, but also raise an E_NOTICE or E_WARNING -- things you might be able to recover from, or conditions where you may want to raise an exception. So, at times, you find yourself writing code like this: if (false === ($fh = @fopen($filename, 'r'))) { throw new RuntimeException(sprintf('Could not open file "%s" to read', $filename)); } Seems straight-forward...

Sebastian Bergmann's Blog: Using CLANG/scan-build for Static Analysis of the PHP Interpreter

Sebastian Bergmann's Blog: Using CLANG/scan-build for Static Analysis of the PHP Interpreter
In a new post to his blog Sebastian Bergmann takes a quick look at using a static analyzer, clang and scan-build, to analyze the PHP interpreter (specifically during the compile process).I have been tinkering with CLANG's static analyzer lately. This post summarizes how I installed LLVM and CLANG and performed the analysis of a build of the PHP interpreter.He includes all the commands (unix-based) to get the clang tools/libraries installed in the correct places as well as what to add to your $PATH to get...

Using CLANG/scan-build for Static Analysis of the PHP Interpreter
I have been tinkering with CLANG's static analyzer lately. This post summarizes how I installed LLVM and CLANG and performed the analysis of a build of the PHP interpreter. First, we need to obtain the CLANG and LLVM source trees and build CLANG: cd /usr/local/src mkdir clang cd clang svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm cd llvm/tools svn co http://llvm.org/svn/llvm-project/cfe/trunk clang cd ../../ mkdir build cd build ../llvm/configure --enable-optimized --disable-assertions make...

Cracks in the Foundation

Cracks in the Foundation
PHP has been around for a long time, and it's starting to show its age. From top to bottom, the language has creaky joints. I've decided to take a look at how things got to this point, and what can be (and is being) done about it. I start out pretty gloomy, but bear with me; I promise it gets better. In the Beginning, There Was Apache and CGIAnd there was much rejoicing.In 1994, Rasmus Lerdorf created the aoPersonal Home Page Tools,a a set of CGI binaries written in C. These tools looked...

Henrik Bjørnskov's Blog: Stampie an in depth look
Henrik Bjørnskov has posted a bit of an in-depth look at Stampie, an abstraction library for sending emails from PHP applications via various service providers (like SendGrid and Mailchimp).So what is Stampie. Stampie is a API wrapper for the most common email sending services. It provides a standard PHP Api to send emails. But mostly it is a project to test TDD and experiment with a couple of different things. Stampie is developed with Dependency Injection and therefore there is a lot of objects. At...

PHPMaster.com: Learning Loops

PHPMaster.com: Learning Loops
PHPmaster.com has a new introductory tutorial for those just starting out with PHP (or with programming really) talking about using looping structures for sets of data - for, while/do-while and foreach.A significant advantage of computers is that they can perform repetitive tasks easily and efficiently. Instead of writing repetitive code you can write a set of statements that processes some data and then have the computer execute them repeatedly by using a construct known as a loop. Loops come in several...

PHPClasses.org: Can .NET make PHP run faster than the official PHP implementation?

PHPClasses.org: Can .NET make PHP run faster than the official PHP implementation?
On the PHPClasses blog today the question is posed "can .NET make PHP run faster than the official PHP implementation?" (relating to the use of the Phalanger tool to compile PHP down to .NET assemblies.Recently Phalanger 3.0 was released introducing numerous improvements in terms of compatibility with the PHP 5.3, interoperability with .NET platform implementations including Mono on Linux, and probably most importantly performance improvements. [...] What motivated this article was that a PHP developer...

16.12. Eine EinfAhrung in Behavior Driven Development

16.12. Eine EinfAhrung in Behavior Driven Development
Testdriven Development, also das Schreiben eines oder mehrerer Tests bevor der eigentliche Code entsteht, ist inzwischen ein alter Hut. Ein groAYer Nachteil dieses Verfahrens ist, dass im agilen Umfeld die User Stories erst verstanden werden mAssen. Wenn die Story aber falsch verstanden wurde, dann wird auch der Test falsch implementiert. Knackpunkt ist also immer noch der Abgrund zwischen Analyse und Verdeutlichung der GeschAftsprozesse sowie dem korrekten Erfassen und testen eben jener. Eine LAsung...

Can .NET make PHP run faster than the official PHP implementation?
Can .NET make PHP run faster than the official PHP implementation? By Manuel Lemos Phalanger is compiler that generates .NET assemblies from PHP code, so it runs in a .NET virtual machine. The latest benchmarks seem to indicate that PHP applications compiled by Phalanger execute noticeably faster than when they are executed by the official PHP implementation based on Zend engine, even when a caching extension is used. Read this article to learn how Phalanger works and what lessons can be learned to...

15.12. Using custom annotations in PHP

15.12. Using custom annotations in PHP
When developing enterprise software one should always keep an eye on writing code that is easily maintainable, testable and extendable. Design patterns already propose a way to implement a loosely coupled architecture. With annotations you can take a step forward to make your code look even more expressive, focusing on the primary problem instead of writing a lot of boilerplate code. A single comment line can save you many more lines of code but as it is written in the project's domain language it will...

Cross-Origin Ajax with CORS

Cross-Origin Ajax with CORS
There's no doubt that Ajax is one of the most exciting, useful, and necessary web technologies available to front-end developers. Unfortunately, it's also one of the most restrictivea-aespecially when it comes to gathering content from other domains. Web developers are nothing if not persistent, so we've come up with a variety of ways to get around cross-origin restrictions, including JSONP, server-side proxies made with PHP, ProxyPass proxying, Flash transports, creative iFrame uses, and more. What many...
