Alternatives

Some of the reasons

12. Web Servers
For serving.. the web.

13. Get it right
Web servers should serve static content
Hand off to a PHP processor to handle PHP
Client Web PHP
Request Server Handler
There is so much more
Caching, Tagging, proxying, reverse

24. Popular PHP approaches
(Some of them)
mod_php (Apache)
FastCGI
PHP-FPM
PHP Builtin Server ?

25. Apache
mod_php
Old faithful

26. Apache + mod_php
Loaded as an Apache Module
Apache becomes capable of interpreting PHP
files
Part of the rendering process hooks
mod_php
Output served as normal

27. Apache
mod_fastcgi
Old. Faithful?

28. Apache + mod_fastcgi
Just because it includes “fast” in its name ...
Allows passing requests matching rules to an
external process
Passes filename for execution
Loads configuration on each access (slower)

29. Nginx
PHP-FPM
New, awesome!
(in my opinion)

30. Information
Appliances
A term coined by Jef Raskin, 1979
“Designed and pre-configured for a single application”

31. Nginx
Some background

32. Nginx
Event based
Non-blocking
Asynchronous request handling
Single thread
Designed for speed

33. Nginx
Proxying built in
Proxy requests off to external processes
Network, or unix socket

34. Nginx + PHP-FPM
Nginx serves static content (fast)
PHP-FPM handles launching processes for
PHP
Loads config once
PHP managed separately from Webserver
Pool management

36. Thanks!!
