Get a Handle on PHP Handlers
Mar 25, 2015 @ 10:25:47

On DZone.com today there's a post covering the different kinds of handlers that can execute PHP - those pieces of code that work with the web servers we use every day to interpret and execute PHP code.

PHP Handlers? mod_php? FPM? How do we make sense of the inner workings of PHP outside of our lines of code? We know we can run PHP on the server to build web applications swiftly, but how can we optimize our environment and configurations to reach maximum scale? We know that PHP has its drawbacks for not being asynchronous or event-driven, which is all the more reason to ensure maximum optimization. The impact of your server environment on your PHP application performance can be more than you think you can afford. A careful examination of your PHP ecosystem will help you avoid suffering performance loss in areas you can otherwise solve for easily.

They provide a brief summary of what PHP handers, well, handle and where they fit in the overall architecture of execution. They then get into the details on some of them:

  • CGI – mod_cgi
  • suPHP – mod_suphp
  • DSO – mod_php
  • FastCGI – mod_fcgid
  • FPM (FastCGI Process Manager) – php-fpm

Included in each is an overview of how it works and some of the main advantages (and disadvantages) of their use. He also mentions two of the most popular web servers that work with these handlers: Apache and Nginx.

Running PHPUnit via Phing on HHVM
Feb 26, 2015 @ 09:16:58

Stephan Hochdörfer has a quick post showing how he has PHPunit up and working on an HHVM instance. His problem was that the tests were actually executing using the "php" binary, not the HHVM one.

For quite some time we run the unit tests for our libs and tools against PHP and HHVM, at least that is what I thought up to now. As it turns out I missed a minor detail. [...] What happens now is that Phing is executed via HHVM but PHPUnit will still be executed via the PHP binary because the PHPUnit shell script will look for the php binary in the PATH configuration. Since we run HHVM side-by-side with PHP on our Jenkins build nodes I was not able to point /usr/bin/php to /usr/bin/hhvm - which would be the easiest and cleanest solution. I

He shares the workaround he created, creating a symbolic link between the hhvm and php binaries and then executing the Phing task to run the tests. This is being run via Jenkins and uses it's "WORKSPACE" as a container so the main "php" binary isn't overwritten.

Mastering Zend Framework:
Building and Executing SQL Queries In Zend
Apr 08, 2014 @ 12:18:17

The Mastering Zend Framework site (from Matthew Setter) has a new post today showing you how to execute SQL queries directly in a Zend Framework v2 application.

Whilst there are many ways for building and executing SQL queries in Zend Framework 2, the two that I usually use, and which are also used in the ZF2 manual, are closures and the selectWith function. I previously wrote a three part series, showing how to get started using the ZendDbSql classes with Zend Framework 2, but I didn’t cover how to actually run them. So in today’s tutorial, let’s do that.

He gives examples of these two methods starting with closures in a "tableGateway" select call. He shows how to add on parts of the query like "wheres" and an "order by" as well as some basic formatting. He then gets into the "selectWith" examples, showing the same criteria just added a different way. He also includes an example of the "tableGateway" objects used for the examples and how they're configured.

Running unit tests when deploying to Windows Azure Web Sites
Jan 30, 2013 @ 10:25:20

Maarten Balliauw has a new post to his site showing you how to execute your unit tests (in this case PHPUnit) when you deploy your instance out to the Windows Azure platform.

When deploying an application to Windows Azure Web Sites, a number of deployment steps are executed. For .NET projects, msbuild is triggered. For node.js applications, a list of dependencies is restored. For PHP applications, files are copied from source control to the actual web root which is served publicly. Wouldn’t it be cool if Windows Azure Web Sites refused to deploy fresh source code whenever unit tests fail? In this post, I’ll show you how.

He creates a super basic script using Silex and writes up a test with some dummy assertions, checking if true equals true. He then steps you through updating the current "deploy.sh" script to add in a call to execute PHPUnit and an "exitWithMessageOnError" statement. This statement kicks it back and causes the deployment to fail when tests don't pass (as seen here).

Sebastian Bergmann:
Using PHPUnit from a PHP Archive (PHAR)
Oct 08, 2012 @ 10:18:52

PHPUnit, the popular PHP unit testing tool, has undergone some changes in its methods of deployment. First it was integrated into the Composer/Packagist dependency management system and now it's been implemented as a phar archive. Sebastian Bergmann explains how to use it in his latest post.

Downloading a single file to use PHPUnit? Not an idea that is too phar out anymore! Starting with version 3.7.5, PHPUnit seems to finally work correctly when packaged as a PHP Archive (PHAR).

He includes a list of steps you can follow to pull down the latest code and use the phar branch that executes with the archive file instead of the local "phpunit" executable. Of course, you can still (as always) install PHPUnit via the PEAR process as well.

Automatic Testing for TDD with PHP
Aug 24, 2012 @ 09:09:04

If you practice the TDD (test-driven development) methodology in your work, you know that sometimes switching back and forth between a terminal and your IDE can be distracting. In this new tutorial from NetTuts.com, they show you how to streamline things a bit with a simple Ruby script.

Traditional test-driven development can, at times, be cumbersome. You have to stop writing code in order to run your tests. Luckily, there are solutions, which provide the ability to automatically run your tests as you code. In this tutorial, you will learn how to use a Ruby gem, called watchr, to monitor your code and automatically run the appropriate tests whenever you save your work.

The IDE doesn't matter in this case because the "watchr" tool keeps an eye on when things change in the watched directory and automatically fires off a script when it sees an update. They include the few short lines of Ruby to make it all happen and even have the "notify-send" command built in to give you a popup about the pass/fail status.

PHP: Best Methods for Running Scheduled Jobs
Jun 28, 2012 @ 11:01:49

On DevShed.com today there's a new article posted looking at methods for running scheduled jobs based on responses to this forum post.

I have a webpage form that requires a date and time to be submitted. When it's submitted I need the back-end to run a script at the time and date specified. Have you ever needed to do something like this?

Some recommendations already posted include:

  • The UNIX "at" command
  • Setting up a queue system to manage the processes (using something similar to Gearman
  • Setting up a cron job to handle the periodic execution of the script.

Gonzalo Ayuso's Blog:
How to use eval() without using eval() in PHP
Mar 13, 2012 @ 10:09:52

In this new post Gonzalo Ayuso talks about "using eval without using eval" in PHP applications - executing PHP code without having to use the eval function to do it.

Yes I know. Eval() is evil. If our answer is to use eval() function, we are probably asking the wrong question. When we see an eval() function all our coding smell’s red lights start flashing inside our mind. Definitely it’s a bad practice. But last week I was thinking about it. How can I eval raw PHP code without using the eval function, and I will show you my outcomes.

He includes some sample code showing a basic script with a class and a loop executing normally, then an "eval version" that puts it all in a string and executes it. He offers a different method - not an ideal one since it requires being able to write to the local file system, but prevents the need for eval - writing the PHP code to a temporary file and using a "fake eval" to pull it in.

Running JavaScript inside PHP code
Mar 01, 2012 @ 09:56:45

On DZone.com Giorgio Sironi has a new post about an interesting new PHP extension that lets you run javascript inside PHP - v8js (VERY alpha right now).

v8js is a new PHP extension able to run JavaScript code inside V8, Google's JavaScript interpreter that powers for example Chrome and NodeJS. This extension is highly alpha - and its API would probably change in the months ahead. Since documentation is lacking, I invite you to repeat the discovering process I follow in this post in case you find some differences in a new version of v8js.

He gives you the (PECL-based) commands to get the extension and it's needed dependencies installed and enabled. He uses PHP's own Reflection features to look at the extension and find its methods including: "executeString", "getPendingException" and "getExtensions". To show it in action, he implements an old standby to test new languages - the FizzBuzz example - in Javascript, executed inside the PHP. He also includes a quick example of how to load in an external Javascript file and execute the results.
