The article introduces PHP Fibers, a new feature introduced in PHP 8.1 that allows developers to write asynchronous code and improve performance. Fibers are not threads, but they can make code more efficient by allowing multiple requests to be initiated in parallel and then waiting for all of them to complete. This feature is particularly useful when dealing with external resources such as network requests or sub-processes. The article provides a practical example of using PHP Fibers to create a 30-second clip for each video file in a directory using FFMpeg. By migrating the code from synchronous to asynchronous using fibers, the author demonstrates how the processing time can be significantly reduced. The article highlights the importance of non-blocking execution and provides step-by-step instructions on implementing fibers in PHP code. PHP developers looking to optimize their code and enhance performance will find this article valuable.
