下載安裝PHPExcel庫

下載PHPExcel：http://phpexcel.codeplex.comphp

安裝PHPExcel很是的簡單，只需解壓壓縮包裏的Classes文件夾中的內容到application\libraries\目錄下便可，最終的目錄結構以下：html

– application\libraries\PHPExcel.phpapp

– application\libraries\PHPExcel (文件夾)ide

可是因爲CI的命名規則的約束，須要修改PHPExcel庫中的類名以聽從CI中的類命名規則。打開application\libraries\PHPExcel\IOFactory.php 文件，將其類名從PHPExcel_IOFactory改成IOFactory，並將其構造函數改成public類型。函數

至此，PHPExcel庫安裝完畢。codeigniter

使用PHPExcel庫生成excel文件

在CI中寫一個Controller實現導出功能this

public function export ( )

// 清空輸出緩衝區

// 載入PHPExcel類庫

// 設置當前工做表
$objPHPExcel -> setActiveSheetIndex ( 0 ) ;
// 設置表頭

foreach ( $fields as $field )

// 從第二行開始輸出數據內容

$objPHPExcel -> getActiveSheet ( ) -> setCellValueByColumnAndRow ( 3 , $row , $course [ "stuCount" ] ) ;
$row ++;
}
//輸出excel文件
$objPHPExcel -> setActiveSheetIndex ( 0 ) ;
// 第二個參數可取值：CSV、Excel5(生成97-2003版的excel)、Excel2007(生成2007版excel)
$objWriter = IOFactory :: createWriter ( $objPHPExcel , 'Excel5' ) ;
// 設置HTTP頭
header ( 'Content-Type: application/vnd.ms-excel; charset=utf-8' ) ;
header ( 'Content-Disposition: p_w_upload;filename="' . mb_convert_encoding ( "選課統計表" , "GB2312" , "UTF-8" ) . '.xls"' ) ;
header ( 'Cache-Control: max-age=0' ) ;
$objWriter -> save ( 'php://output' ) ;
}

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，可是若是不加這句話，生成的Excel文件頗有多是亂碼文件，打開時提示的是文件格式無效。一開始我覺得是編碼問題，可是即便我將MySQL，CI，HTML頁面，HTTP頭信息等等全部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，仍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，打開一看仍是亂碼，我才知道不是編碼的問題。最後通過多方的查找，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，而此時若是緩衝區中在Excel文件以前還有其它內容，則會一塊兒寫入到Excel文件當中，致使Excel文件頭中包含髒數據，故而打開時提示文件格式無效。因此切記，在生成Excel文件前，必定記得先清空一下輸出緩衝區！！！編碼

PHPExcel是個強大的類庫，它所能作的不單單隻有這些，更多的功能能夠查看PHPExcel官方的文檔，在這裏我列出了一些經常使用的設置選項。spa
