Exploring Coroutines in PHP
– doeken.org - submitted by Doeke Norg
The term "coroutine" often comes up when talking about asynchronous or non-blocking code, but what does it actually mean? In this post, we will explore coroutines as a concept and see how PHP supports them through Generators and Fibers.

How to Read Big Files with PHP (Without Killing Your Server)
In a new blogpost published at Sitepoint, Christopher Pitt explores the various ways you can handle reading big files in PHP.
Though this isn’t a problem we frequently suffer from, it’s easy to mess up when working with large files. In asynchronous applications, it’s just as easy to bring the whole server down when we’re not careful about memory usage.
This tutorial has hopefully introduced you to a few new ideas (or refreshed your memory about them), so that you can think more about how to read and write large files efficiently. When we start to become familiar with streams and generators, and stop using functions like file_get_contents: an entire category of errors disappear from our applications. That seems like a good thing to aim for!
Save memory by switching to generators
Though the generators look cool, I've never used them much because I didn't find a good use case. Evert Pot demonstrates on his blog how they can help conserve memory.
Since the release of PHP 5.5, we now have access to generators. Generators are a pretty cool language feature, and can allow you to save quite a bit of memory if they are used in the right places.http://evertpot.com/switching-to-generators/
Recursion and Generators
Christopher Pitt experimented a bit with generators and wrote down the thought process on his blog.
https://medium.com/@assertchris/recursion-and-generators-d56f513ea6abGenerators are awesome. If they’re new to you then take some time to read where they come from and what they do. If you’ve come from a particular programming language background, they may be difficult for you to understand.
They were, and continue to be, tricky for me to grasp. So I’ve spent loads of time trying to understand them, and what they can do for my code.
