Server Requirements
- PHP version 5.1.2 or newer (necessary for autoloading models).
(Some extensions may require a newer version of PHP to function correctly.) - CodeIgniter version 1.7.2 or newer.
-
A database supported by CodeIgniter. Read CodeIgniter's Server Requirements.
PostgreSQL and MySQL are tested and supported. Other DBs should work. (Not all databases support all features.)
Using PHP older than 5.1.2
It is possible, by manually modifying the DataMapper library, to get Datamapper ORM to work on PHP older than 5.1.2. PHP 5.0.0 or newer is still required, and it is not officially supported.
Please see this forum post for instructions.
Expression Engine and CodeIgniter 2.0
Please note: Expression Engine and CodeIgniter 2.0 (which has not yet been released at this time) are not officially supported.
Patches and suggestions are welcome, however.
Using Oracle
Oracle probably will not work 100% out-of-the-box.
However, Frank Liu has done some research on how to get Oracle working.
