/**
|
||
|
|
* CI_BASE - For PHP 4
|
||
|
|
*
|
||
|
|
* This file is used only when CodeIgniter is being run under PHP 4.
|
||
|
|
*
|
||
|
|
* In order to allow CI to work under PHP 4 we had to make the Loader class
|
||
|
|
* the parent of the Controller Base class. It's the only way we can
|
||
|
|
* enable functions like $this->load->library('email') to instantiate
|
||
|
|
* classes that can then be used within controllers as $this->email->send()
|
||
|
|
*
|
||
|
|
* PHP 4 also has trouble referencing the CI super object within application
|
||
|
|
* constructors since objects do not exist until the class is fully
|
||
|
|
* instantiated. Basically PHP 4 sucks...
|
||
|
|
*
|
||
|
|
* Since PHP 5 doesn't suffer from this problem so we load one of
|
||
|
|
* two files based on the version of PHP being run.
