Mike Wallner has shared a quick and easy HTTP caching technique in a new post to his blog today. The key is in using the PEAR HTTP_Header package.

Ever watched youself browsing e.g. a web forum? Noticed that you viewed the same page several times? Well, this means extraordinary and useless load for your server if there's no caching mechanism implemented in the web application. Even if there is some file or db cache you can still improve performance with implementing some http cache.

With a few simple lines of code using HTTP_Header, you can tell your scripts how long to set the "expires" header to on your requests. This increment (in seconds) is relayed to the browser to tell it when to next fetch the page and not reload from cache.

Mike Purcell has a new post to his blog showing a method he's followed to be able to use the popular PHPUnit unit testing software without having to go through the PEAR installer to get there.

PHPUnit is a great tool to protect us developers from introducing new defects when adding new features or re-factoring code. However there is one HUGE downside to PHPUnit; it must be installed using PEAR. Personally, I don't like 'auto-installers', I'd prefer to know what exactly is happening behind the scenes with regards to which libraries are required and how they are being called. [...] After breaking down the PHPUnit source code, I realized it could be installed without going through PEAR, and without too much headache.

He walks you through the directories you'll need to set up (test/vendor), the commands you'll need to get the latest version and unpack it, changes to set up some symlinks and updating the PHPUnit source to modify the autoloader, bootstrap and phpunit executable.

On the PEAR blog today there's an update about the migration over to github that 5 million lines of code has already made:

Since October 2011, 5 million lines of the PEAR codebase has shifted to github. Hand in hand with this shift has been the tireless work of Daniel C - someone who brazenly said "I will fix the failing packages!" in the tail end of last year.

As a result of his efforts a list has been created of known good packages to use with PHP 5.4. Other results include:

• All test infrastructure upgrading to PHP 5.4 release candidates
• All database driven test suites executing properly, catching a variety of simple bugs
• Hitting a point of "near zero" patches to be applied to unmaintained packages
• Increasingly, the PEAR QA team is delivering PHP 5.3+ friendly forks of existing packages

Michael Nitschinger has a new post to his blog looking at using the popular Composer tool for package management together with Lithium to make dependency management simpler.

Composer is a command-line tool that helps you manage your application dependencies. It automatically fetches packages, resolves dependencies and is easy to configure. [...] Currently, Lithium doesn't provide Composer packages out of the box, but it's easy to write one.

He starts the post with an introduction to using Composer for those new to the tool, then moves quickly into setting up your "composer.json" file to pull in the Lithium updates from their github account. Additionally, he shows how to add a dependency for twig in the "require" section and pull it down at the same time (with dependencies).

Mike Willbanks has a new post to his blog about a different sort of technique for deploying PHP - building your own RPMs instead of just using the pre-packaged ones. This opens up a whole world of customization options.

In the PHP world, one might ask why not just build it from source? Well, an RPM IS built from source and then distributed to many servers - we can ensure that we have the same packages on each, we can maintain the same versions and if you've read my previous post on Pirum you will know that I also like mirroring PEAR packages.

He walks you through the structure of an RPM package (the spec file, with examples, and the source), the "%prep", "%build" and "%install" containers as well as where the source needs to live for things to work correctly.

In part two of their look at Composer/Packagist, the Nelm.io blog looks at some of the impact they could have if adopted heavily by the PHP community.

In this second part I would like to talk about a few things Composer could do for you, and the PHP community at large, once it is broadly adopted. [...] How can [shared] interfaces be distributed in each project that uses or implements them? This is where I see Composer helping. Composer supports advanced relationships between packages, so to solve this issue you would need three parts.

The three parts all revolve around a few different packages (for their specific Caching interface example) - psr/cache-interface, psr/cache and the requiring of these into a framework needing the common interface. He talks some about what this sort of structure has to offer: simpler plugin installation, promotion of good standards, promotion of code reuse and a renewed interest in using PHP.

Reinventing the package management wheel is another thing that really should stop. Who am I to say this you ask? It is true, we are building a shiny new wheel as well. Yet I take comfort in the fact that we are trying to build a generic solution which will work for everybody.

On the PEAR Group blog there's a new post welcoming all new contributors to the project and pointing out that the PEAR account on Github has officially passed the 200 repository mark in the move from SVN to Git.

PEAR is about providing the PHP community with reusable, effective components - this has been our mission since day 1. If there is anything we can do to make that goal happen, to assist you as an individual or company, I would strongly encourage you to let us know - we're here to help.

They mention the work of two individuals that have done good work on a specific package, meldra and Gemorroj - perfect examples of how the move to Github has made it simpler to implement changes that have been "waiting in the wings" on the XML_Feed_Parser and Image_Barcode2 packages.

If you've had changes you've wanted to make to a PEAR package in the past but haven't ever gotten them submitted, there's not a better time than now.

On the Nelm.io blog today there's a new post (part one of a series) about using Composer and Packagist to manage PHP applications as packages.

You may have heard about Composer and Packagist lately. In short, Composer is a new package manager for PHP libraries. Quite a few people have been complaining about the lack of information, or just seemed confused as to what it was, or why the hell we would do such a thing. This is my attempt at clarifying things.

The briefly explains what the tool(s) do and shows how to set up the configuration on both sides - Composer to manage the packages and the package definition configurations (including meta about the project and any dependencies). He also answers several "why" questions about the need for a package manager, using this versus PEAR, the choice of JSON for config definition and a current status of the project.

On NetTuts.com today there's a new tutorial showing off a package management system for the CodeIgniter framework, Sparks, that makes installing and using packages similar to Ruby's gems.

Sparks is a new package-management system for CodeIgniter that extends the core with support for gem-like sparks. This tutorial interweaves an entry-level overview of the architecture and usage of the sparks system with the creation of dovecote-a simple spark for managing RSS data.

The tutorial introduces you to the Sparks system and helps you get it installed and configured to work with a first basic package - a dovecote example. He helps organize and write the first spark as well as set up any dependencies and autoloading it might need. He follows this by adding some functionality to the package to make pushing output to the view simpler.

You can download the source for the complete tutorial's code.

If you missed out on the Future of PEAR/Pyrus webcast event put on by Engine Yard, you're in luck - they've posted a recording of the event.

In this panel discussion, we tackle topics including the direction PEAR and Pyrus will be going in the next few years, obstacles that may be on the horizon, and more.

PEAR is the package library of standardized packages for a variety of common development tasks. Pyrus is a new package manager to make installing and maintaining PEAR packages simpler. Engine Yard's next webcast will cover the Lithium framework with core contributors Nate Abele, Garrett Woodworth, and John Anderson on December 1st.
