Some seriously good news here. It took several years of waiting,but,it finally happened. PHP-FPM project is officially BSD-licensed now,which means,that it has good chances to become a part of official PHP distribution.
PHP-FPM is “deciphered”as “PHP FastCGI Process Manager”and is a patch for php to greatly improve FastCGI SAPI usage in production. It adds a bunch of additional features to php’s fastcgi such as:easy php-process daemonization (with ability to specify uid/gid/chroot/log-file),safe php-processes restart (without losing requests),custom error-handling and accelerated file-upload support (requires additional support from web-server).
There’s not much documentation in english,currently,but,again,there is a good chance that it will be added really soon.
