PHP-FPM (an acronym of FastCGI Process Manager) is a hugely-popular alternative PHP (Hypertext Processor) FastCGI implementation.
As you may or may not know, PHP is one of the biggest open-source software programming languages utilized online. It features heavily in web development across such well-known platforms as Drupal, Magento, and WordPress, and was originally devised to preprocess plain text in UTF-8.
When PHP was invented by Rasmus Lerdorf in the mid-’90s, it was one of the first languages capable of featuring within HTML coding with no need to call external files.
Lerdorf’s scripting language has continued to evolve over the decades since, and it’s now supported by any web platform or operating system. However, as PHP’s publication is under the PHP licence, it’s incompatible with GNU General Public License because of restrictions related to the PHP term.
PHP-FPM Key Features
PHP-FPM includes numerous features that can prove beneficial for websites receiving traffic in large volumes frequently. These are:
- Ability to start workers using various uid/gid/chroot/environment and php.ini, which replaces the safe mode users may expect
- In-depth management for simple stop/start processing
- Logging of stdout and stderr
- Emergency restart available, in the event of an opcode cache being destroyed accidentally
- Support for uploads is faster
- Based on php.ini configuration files
- Slowlog variable configuration for detecting functions that take longer than usual to execute
- FastCGI improvements, with a special function for stopping and downloading data while completing long processes (e.g. processing statistics)
- Basic stats are available, similar to the mod-status module in Apache
