DSO – Dynamically Shared Objects
Apache with PHP can be installed in two different ways.
- Statically embed the PHP binary into the Apache binary. This is probably the fastest and best way to run PHP
- Install Apache and PHP is by using Apaches DSO module
Apache supports adding modules on instead of embedding them in the httpd binary. This works well when you dont want to re-compile Apache each time a module is updated, or if you want to add on numerous modules for development purposes
System Administrators Dream: Allows developers to upgrade PHP without having to recompile Apache
