PHP has outgrown it's web roots

You've been working with PHP for a while and have watched it grow for it's roots as a simple templating language to powering some of the largest sites in the world. Facebook. Wikipedia. WordPress. You've started creating more complicated applicationsthat now need some work done other than displaying content to the screen. You want to leverage your PHP knowledge to create tools to let you get things done. 

Server-level programming can be a pain

Deployment scripts, database migrations, asset minification, queue workers, these are all things you need to worry about in modern web applications. There's information out there on how to accomplish these tasks with PHP, but what you really want is one reference guideto show you how to do it at the lowest levels. 

You need a foundation in using it on the CLI to response to OS level signals

PHP gives you the opportunity to leverage your existing skills and libraries in new ways.One of the things you will want to do when building CLI scripts is respond to OS level signals. Everything from KILL to the user defined USR signals are available to you to trap and branch your code as necessary. While PHP was built for the web, it has grown into a tool that can do so much more. "Signalling PHP"is your gateway into understanding how PHP interacts with operating systems. Why not use the mostpopular langauge on the web to creating tools on the server?

Don't wait! Get your copy of "Signaling PHP" today

Testimonials
"I've never gotten very involved in the CLI, but reading Signaling PHP made me write my first command line app. This book is invaluable for anyone writing apps that interact with the command line!" - Brandon Savage

Stop reinventing the loop

Looping over collections is something all programmers do. We keep writing the same code and building the same loops in project after project.  PHP has us covered though. We don't have to continue to re-invent the loop, we can use the tools provided.

The Standard PHP Library (SPL) gives you the tools you need

An important part of the SPL is the collection of Iterator classes and interfaces. These bits of magic, like the rest of the SPL, will change the way you program. They are power tools in every PHP programmer's toolbox. Like other power tools, if used safely, they can make a difference in how you code, and how fast.

Iterators help you create better programs, "Iterating PHP Iterators" will help you create iterators

"Iterating PHP Iterators" will show you the basic of PHP's Iterators. You will see how to implement them in your own code, as well as use them to do eveyrthing form filtering input to stupid party tricks. 

This is a great book for beginners and intermediate developers. It’s a comprehensive introduction to iterators and some of the implementations that ship with the SPL.

 - Christopher Pitt (Iterating PHP Iterators Review)

Easy start for beginners, but enough meat for those who already use Iterators 

- Mark (@Mark_Baker) Baker

#IteratingPHPIterators by @CalEvans is a great quick reference book if you use them regularly, or a good starter if you haven’t

- Ian (@icawebdesign) H.

Finished @CalEvans 'Iterating PHP Iterators'. Nice read. Should use them more often, especially to filter when looping.#php
