PHP-FPM

PHP-FPM (FastCGI Process Manager) is the primary PHP FastCGI implementation bundled with PHP for handling heavy-loaded sites, providing advanced process management with multiple worker pools, graceful start/stop, adaptive process spawning (static, dynamic, ondemand), slowlog tracking, and accelerated upload support. It is configured via php.ini-style pool files and is typically deployed behind a web server such as Nginx, Apache, Caddy, or LiteSpeed via FastCGI. PHP-FPM exposes operational status pages (in plain, JSON, XML, OpenMetrics, and HTML formats) but does not provide a public HTTP API; it runs only on POSIX systems that support fork().
