That’s because php-fpm does not support asynchronous, real-time communications using protocols such as Websockets. In some benchmarks, you can increase PHP performance (throughput) by 100 times, by enabling asynchronous PHP via Swoole, instead of using a process accelerator such as php-fpm with synchronous code. Because asynchronous processing enables the management and completion of more than one task at a time, you can dramatically boost PHP performance by using it instead of synchronous PHP. Does Asynchronous Processing Boost PHP Performance? There are two types of API calls synchronous calls, which must be completed before code execution resumes on the API and asynchronous calls, which do not pause code execution on the API - instead issuing a "callback" when the call is completed. What Are Synchronous and Asynchronous Calls? Prefork with either mod_php with Apache or php-fpm with either Apache or Nginx. PHP was originally created to support synchronous development, so most PHP developers are used to writing only synchronous code with the language. When it completes one task, it moves on to the next one in the queue. So with synchronous PHP, the CPU can process only one I/O task at a time. Individual tasks must be completed before you can start another one. Our 2023 PHP Landscape Report showed async features as the 5th most valuable feature set for PHP developers.ĭownload the report free to unlock additional insights into async PHP. Are Async PHP Features Important to PHP Developers? How Do You Enable It?īy using extensions such as Swoole, or a framework for PHP such as ReactPHP, you can make it possible for your PHP applications to accept requests and responses asynchronously, using event loops. By making it possible for your applications to manage many requests at once, they can take full advantage of available hardware resources, which can boost ROI and service levels at the same time. It does this by keeping non-blocking I/O tasks running in the background, and letting the CPU process other tasks as it’s waiting for data and instructions needed to complete the I/O tasks. The idea behind asynchronous PHP is to take full advantage of all available CPU cycles to boost PHP performance. Not only does this slow overall application performance, but also, it lowers hardware utilization. This is critical because traditionally, there’s a lot of time when a CPU sits idle while a PHP application manages I/O tasks. ![]() In other words, asynchronous applications can multi-task. Let's get started with the basics What Is Asynchronous PHP?Īsynchronous PHP refers to PHP code that is written using the asynchronous model. In this blog, we look at asynchronous PHP, how it works, how it's used, and how it compares to synchronous PHP. Developers rely on asynchronous PHP calls to fulfill requests without bogging down the application - but that hasn't always been the case. ![]()
