Xdebug hooks into PHP's internals deeply in order to offer it's fetures of step debugging, tracing, profiling and others. So each PHP version has a matching Xdebug version.
The latest version of Xdebug, Xdebug 3, only supports PHP versions back to 7.2. However, that's a longer support period than even PHP itself provides.
See the compatibility table for more info: https://xdebug.org/docs/compat#supported-versions
In this talk, I'll discuss how to appply asynchronous programming techniques to solve common problems in Magento.
After a quick introduction to the basics of asynchronous programming, I'll show you how frameworks like ReactPHP and AmPHP can take PHP beyond the traditional 'run the script, execute some code and die' paradigm and demonstrate some novel and unique ways that asynchronous programming can be used in your Magento store.
Note: This guide assumes you are using PHP-FPM and Ubuntu 16.04
Speed (and therefore time) is of the essence
Xdebug is a fantastic tool which can save hours or even days of debugging effort.
Yet just enabling the extension itself will slow down Magento. Composer will also warn you of performance degradation when running it with Xdebug enabled.
