Creating a CodeIgniter library is an easy task, for example, take this PHP library:
http://code.google.com/p/php-excel/
The php-excel
library created by Oliver Schwarz is used to generate Excel files—a task that is needed from time to time. Again, this example is not one of our main examples, but it's a good way to see how a library is created. Now, you will be able to create your own and use them.
First, download the library. It comes in a ZIP file, with four files:
license.txt
: Here we can see the license under which the library is shippedreadme.txt
: Here we can see the change log and some instructions about how to use the librarytest.php
: Here we can see an examplephp-excel.class.php
: Here the library is stored; it is the class file that contains all the methods we need to generate Excel files
CI libraries are placed inside the application/libraries
folder, and we are going to create a new one there. Call this new library excel.php
, open it, and copy all the code...
