PHPExcel is a pure PHP library for reading and writing spreadsheet files and CodeIgniter is one of the well known PHP MVC Framework. In this tutorial, I am gonna show you how to Integrate PHPEXcel library in CodeIgniter with simple steps.
Here is my another post, you might be interested in – How to generate Excel using PhpSpreadsheet in CodeIgniter?
Setp 1: Download and setup CodeIgniter.(download it here: https://ellislab.com/codeigniter)
Setp 2: Download PHPExcel.(download it here: http://phpexcel.codeplex.com/)
Setp 3: Unzip or extract the downloaded PHPExcel lib files and copy Class directory inside files to application/third-party directory(folder).
setp 4: Now create one file called EXcel.php in application/library folder [application/library/Excel.php]. Then include PHPExcel Class to it. see how I did it below

if (!defined('BASEPATH')) exit('No direct script access allowed'); require_once APPPATH."/third_party/PHPExcel.php"; class Excel extends PHPExcel { public function __construct() { parent::__construct(); } } |
That’s it now you can use PHPEXcel methods inside your CodeIgniter application.But you should load it before using it methods(Ex: $this->load->library(‘excel’);)
