我們用最簡單的方法直接用php+mysql來實現了,代碼如下:

<?php

include('db/db.php'); //包含連庫類

$db = new db();

$result = mysql_query('select * from market_sig into outfile "d:product3.xls";');

var_dump($result);

?>

上面是我們的原生php結合了mysql outfile文件導出方法,這種方法有個問題就是不能實現下載功能,只在生成在服務器上.

下面方法更全面:下載PHPExcel：http://phpexcel.codeplex.com

先來看看代碼,代碼如下:

<?php

class Table_export extends CI_Controller {

function __construct()

{

parent::__construct();

// Here you should add some sort of user validation

// to prevent strangers from pulling your table data

}

function index($table_name)

{

$this->load->database();

$query = $this->db->query("select * from `$table_name` WHERE del= 1");

// $query = mb_convert_encoding("gb2312", "UTF-8", $query);

if(!$query)

return false;

// Starting the PHPExcel library

$this->load->library('PHPExcel');

$this->load->library('PHPExcel/IOFactory');

$objPHPExcel = new PHPExcel();

$objPHPExcel->getProperties()->setTitle("export")->setDescription("none");

$objPHPExcel->setActiveSheetIndex(0)

->setCellValue('A1', iconv('gbk', 'utf-8', '中文Hello'))

->setCellValue('B2', 'world!')

->setCellValue('C1', 'Hello');

// Field names in the first row

$fields = $query->list_fields();

$col = 0;

foreach ($fields as $field)

{

$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);

$col++;

}

// Fetching the table data

$row = 2;

foreach($query->result() as $data)

{

$col = 0;

foreach ($fields as $field)

{

$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $data->$field);

$col++;

}

$row++;

}

$objPHPExcel->setActiveSheetIndex(0);

$objWriter = IOFactory::createWriter($objPHPExcel, 'Excel5');

//發送標題強制用戶下載文件

header('Content-Type: application/vnd.ms-excel');

header('Content-Disposition: attachment;filename="Products_'.date('dMy').'.xls"');

header('Cache-Control: max-age=0');

$objWriter->save('php://output');

}

}

?>

看看配置方法吧.

1) 解壓壓縮包里的Classes文件夾中的內容到

applicationlibraries目錄下,目錄結構如下:

-- applicationlibrariesPHPExcel.php

-- applicationlibrariesPHPExcel(文件夾)

2) 修改applicationlibrariesPHPExcelIOFactory.php 文件

-- 將其類名從PHPExcel_IOFactory改為IOFactory,遵從CI類命名規則.

-- 將其構造函數改為public.

還有很多方法像這種方法多喜歡用,因為phpexcel這個插件很實用,對excel表格操作方便.
