Course Introduction:In the implementation of web crawlers, asynchronous multi-threading can greatly improve the efficiency of crawling. As a mainstream programming language, PHP can also implement asynchronous multi-threaded crawlers through concurrent programming. This article will introduce the specific implementation method. 1. Overview of asynchronous multi-threaded crawlers Asynchronous multi-threaded crawlers mainly rely on two technologies: asynchronous IO and multi-thread processing. In traditional synchronous IO, the thread will wait for the IO operation to complete before proceeding to the next operation. In asynchronous IO, threads can perform operations while waiting for IO operations.
