php 中mysql导出excel文件方法

我们用最简单的方法直接用php+mysql来实现了,代码如下:

<?php

include('db/db.php'); //包含连库类

$db = new db();

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

var_dump($result);

?>

上面是我们的原生php结合了mysql outfile文件导出方法,这种方法有个问题就是不能实现下载功能,只在生成在服务器上.

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

先来看看代码,代码如下:

<?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');

//发送标题强制用户下载文件

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) 解压压缩包里的Classes文件夹中的内容到

applicationlibraries目录下,目录结构如下:

-- applicationlibrariesPHPExcel.php

-- applicationlibrariesPHPExcel(文件夹)

2) 修改applicationlibrariesPHPExcelIOFactory.php 文件

-- 将其类名从PHPExcel_IOFactory改为IOFactory,遵从CI类命名规则.

-- 将其构造函数改为public.

还有很多方法像这种方法多喜欢用,因为phpexcel这个插件很实用,对excel表格操作方便.
