Asynchronous PHP | Codesushi - Warsaw 2017

Krzysztof (Chris) Ozog

1. Asynchronous PHP is possible using options like PThreads or forks to allow non-blocking operations. 2. Asynchronous PHP can be useful for applications that spend a lot of time waiting, like websockets. 3. ReactPHP is a popular option for asynchronous PHP that uses a reactor pattern similar to Twisted or Node.js and includes Ratchet for websockets support.

Asynchronous PHP Chris Ozog
Hi! Im Chris Supposedly, I love PHP. But can it really be loved? You want to contact me? Write, and perhaps Ill write back: /krzysztofozog
A few words about me... A Philosopher and a Developer in one Whats even worse is that its documented with two diplomas Although, more of a developer: A creator of web apps for more than a decade now Created my first PHP app in 2004 Addicted to clean code Technical leader at Codesushi A passionate CodeReviewer
The agenda of this grand meeting 1. Asynchronous PHP is it even possible? 2. What can it be useful for? 3. A word or two about... reactPHP 4. Fine words butter no parsnips, meaning Promises in PHP
SPOILER: Yes! 1. Is it even possible?
Asynchronicity in PHP? Asynchronous vs. multithreading vs. forking a revision of terms Asynchronicity is more of a philosophy than a specific mode of implementation What are the available options with PHP PThreads Forks (PCNTL)
Possible applications of an asynchronous PHP 2. What can it be useful for?
Using an asynchronous PHP First of all, there is no one universal rule! We can use it everywhere where the app spends much time waiting Websockets Should we start writing in an asynchronous mode all the time now? - No!
So the most popular option for an Asynchronous PHP 3. reactPHP
Exists since 2012 (current version - 0.4.2) Reactor pattern (as Twisted or nodejs) Ratchet websockets on react
How to avoid callback hell?! 4. Promises in PHP
Promises What is a promise? - Syntactic sugar Two main implementations in php Guzzle/promises reactphp/promise Using promises: Simultaneous queries to api [Guzzle] Organizing an asynchronous code
Summary Asynchronous PHP its possible! No sense in using it everywhere ReactPHP may be helpful Promises can also be used independently
Thank you for your attention! Questions? If needed, it will be easier to reach me this way: /krzysztofozog chris@codesushi.co
