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');
- $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();
-
-
-
- }
-
- function index($table_name)
- {
- $this->load->database();
- $query = $this->db->query("select * from `$table_name` WHERE del= 1");
-
- if(!$query)
- return false;
-
-
- $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');
-
- $fields = $query->list_fields();
- $col = 0;
- foreach ($fields as $field)
- {
- $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 1, $field);
- $col++;
- }
-
-
- $row = 2;
- foreach($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');
-
-
- 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.
