fpm_main

fpm_main是FastCGI Process Manager（快速CGI进程管理器）的主程序，是一个用于管理FastCGI进程的PHP扩展。它允许你在一个单一的PHP进程中运行多个独立的FastCGI应用程序，从而提高了服务器的性能和效率。通过使用fpm_main，你可以更好地控制和管理你的PHP应用程序，实现负载均衡、故障切换等功能。此外，fpm_main还提供了一些高级特性，如内存管理和进程监控，帮助你更好地优化你的PHP应用程序。总之，fpm_main是一个非常实用的PHP扩展，对于需要处理大量并发请求的网站来说，使用fpm_main可以显著提高网站的性能和稳定性。
