Why PHP fastcgi is more efficient

Why does PHP not write a server that directly handles front-end requests, rather than going through the FASTCGI protocol. I know that the new version of PHP has been brought with a server, but that can only be used as a demonstration, not as a production environment

Because the Web server will not write the script interpreter Ah, the reverse is the same. So the best thing is for everyone to do their job and exchange information through an agreed protocol (FASTCGI).

The core is a word: resource reuse.
