Multiple classes in one library

#1

Hello,

I am creating a series of web applications and i was thinking to separate each app into its own library. But i wanted to know if it was possible to have more than 1 class defined in each library for example:
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Testcenter
{
   function one
   {
   }
}

class Test extends Testcenter
{
   funtion addTest()
   {
   }
}
?>

and so on...?

Thanks

You can have as many classes defined as you like. But...

You would normally load a library like this (in a controller for instance):

Code:
$this->load->library('testcenter');
$this->testcenter->dosomething();

In this scenario, the load function is looking for a file called testcenter.php and then looking inside for the class by the same name and instantiating it. However, you would also be able to do this:
Code:
$this->load->library('testcenter');
$t = new Test();
$t->addTest();

Take a look in the manual for the section called "Creating your own Libraries" for more details on naming and such.

The above way will work fine, but do you really need them in the same file? Might get a little confusing like that and as the classes grow it will be a nightmare to maintain. The following would work fine as two files:

Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Testcenter
{
   function one
   {
   }
}

Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Test extends Testcenter
{
   funtion addTest()
   {
   }
}
?>

Then you could load them like this:

Code:
$this->load->library('testcenter');
$this->load->library('test');

You have never written a .dll with multiple related classes..?
