It is meaningless to leave the demand scene to talk about technology. PHP's greatest advantage lies in its rapid development, its disadvantage lies in its efficiency and engineering specifications. These technologies, such as co-processes and asynchrony, are relatively expensive to learn and have the advantage of significant performance gains. This is a paradox with the advantages of the PHP language itself.
Fast implementation of a requirement is a top priority for PHP developers, and performance issues are secondary until the volume of business grows large enough.
PHP's co-implementation and asynchronous implementations are too elegant. People who are interested in research will inevitably compare Golang's go, node. js, and even Java multithreading. After comparison it is not difficult to find that the implementation of PHP is too rough.
The above describes why PHP's yield association and swoole This asynchronous framework is not cold? , including the content of the Yield,wool, I hope to be interested in PHP tutorial friends helpful.
