CGI,FastCGI,PHP-FPM,PHP-CLI,modPHP 向右看齐 2021-12-15 14:47 196阅读 0赞 *This might give you a broader understanding of their difference:* **CGI:** (common gateway interface) It is a specification "protocol" for transferring information between a Web server and a CGI program. A CGI program is any program designed to accept and return data that conforms to the CGI specification. Basically it's a way to run a server side script (PHP, Perl, Python,...) when a HTTP request comes. CGI is very slow in comparison to other alternatives. -------------------- **FastCGI:** is a better CGI. Fast CGI is a different approach with much faster results. It is a CGI with only a few extensions. FastCGI implementation isn’t available anymore, in favor of the PHP-FPM. -------------------- **PHP-FPM:** (FastCGI Process Manager), it's a better FastCGI implementation than the old FastCGI. It runs as a standalone FastCGI server. In general it's a PHP interface for the web servers (Apache, Nginx..) to allows Web Server to interact with PHP. Unlike the **PHP-CLI** which is a command line interface for PHP to allows Users to interact with PHP via terminal. -------------------- **mod\_php:** an Apache module to run PHP. It execute PHP scripts inside the Web Server directly as part of the web server without communicating with a CGI program. -------------------- **mod\_SuPHP:** is similar to mod\_php but can change the user/group that the process runs under. Basically it address some problems of mod\_php related to permissions. 转载于:https://www.cnblogs.com/kidsitcn/p/10506816.html
