Is Codeigniter case sensitive?

Is Codeigniter case sensitive? For example I load a library:
this->load->library("TEST") with the library name all capitals and then, can I use this->test->dummy with the "test" all low cases?

Look at the loader class. It's not consistent. Some will search for the name as is and if it doesn't find it it checks to see if a lower-cased version exists and loads that if it does.

Personally, I write filenames that I create in all lower-case, except when extending a core class with MY_
I define classes with upper-case first letter (class Some_class extends CI_Controller)
When using the loader, I always use lower-case ($this->load->library('test'))
When referencing something that has been loaded, I always use lower-case ($this->test->some_method())

And never have any problems, regardless of operating system.

Thanks for your quick reply.
Actually I am looking at somebody's PHP code which is using Codeigniter, and I find he uses
this->load->library("Test") and latter on he uses this->test->dummy to call the "Test" library. I just want to confirm if the "Test" loaded library is the same as the called "test".

Thanks again.

If you took a closer look at the CI core (mainly the loader-class), you will find this line of code

Code:

// Set the variable name we will assign the class to
// Was a custom class name supplied?  If so we'll use it
$class = strtolower($class);

which implies that everything in CI is accessed by $this->lowered_class_name and nothing else. Following the naming conventions for libraries, controllers, and models would also never make a

Code:

$this->load->library('UPPERCASE_Library');

possible, since it should be avoided using the CI naming convention (cannot find the link at the moment)
