下載安裝PHPExcel庫
下載PHPExcel：http://phpexcel.codeplex.com
安裝PHPExcel非常的簡單，只需解壓壓縮包裏的Classes文件夾中的內容到application\libraries\目錄下即可，最終的目錄結構如下：
– application\libraries\PHPExcel.php
– application\libraries\PHPExcel (文件夾)
但是由於CI的命名規則的約束，需要修改PHPExcel庫中的類名以遵從CI中的類命名規則。打開application\libraries\PHPExcel\IOFactory.php 文件，將其類名從PHPExcel_IOFactory改爲IOFactory，並將其構造函數改爲public類型。
至此，PHPExcel庫安裝完畢。
使用PHPExcel庫生成excel文件
在CI中寫一個Controller實現導出功能

注意事項
1 2 | // 清空輸出緩衝區 ob_clean(); |
我翻看了網上許多例子，當中都是沒有這句話的，但是如果不加這句話，生成的Excel文件很有可能是亂碼文件，打開時提示的是文件格式無效。一開始我以爲是編碼問題，但是即使我將MySQL，CI，HTML頁面，HTTP頭信息等等所有相關的東西的編碼都統一爲UTF-8或GBK或GB2312，內容也都用iconv轉碼，還是一如既往的出現亂碼，後來搞得我頭都大了，一氣之下生成一個空的沒有任何內容的Excel文件，打開一看還是亂碼，我才知道不是編碼的問題。最後經過多方的查找，才知道是PHPExcel輸出Excel文件時是將整個緩衝區中的內容寫入到Excel文件，而此時如果緩衝區中在Excel文件之前還有其它內容，則會一起寫入到Excel文件當中，導致Excel文件頭中包含髒數據，故而打開時提示文件格式無效。所以切記，在生成Excel文件前，一定記得先清空一下輸出緩衝區！！！

PHPExcel是個強大的類庫，它所能做的不僅僅只有這些，更多的功能可以查看PHPExcel官方的文檔，在這裏我列出了一些常用的設置選項。
