PHP编程：PHP导入导出Excel代码

PHP教程
<?php
//传入要导入的Excel的文件名
function import_to_DB($filename) {
  require_once'reader.php';
  $data = new Spreadsheet_Excel_Reader();   //创建读取Excel的对象
  $data->setOutputEncoding('utf-8');  //设置读取Excel内容后输出的字符编码
  $data->read("data/Excel/{$filename}.xls");
  $db = mysql_connect('localhost','用户名','暗码') or die("Could not connect to database."); //连接数据库  
  mysql_query("set names 'uft8'"); //输出中文  
  mysql_select_db('数据库名'); //选择数据库  
  error_reporting(E_ALL ^ E_NOTICE);
  for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) {
    echo $data->sheets[0]['cells'][$i][列数];
    //这里可以把每一行相应列的值插到数据库中,如：
    /*
    $sql="insert "表名" values(对应项...)";
    mysql_query($sql);
    可加上错误判断
    */ 
  } 
?>

header('Content-type: text/html; charset=utf-8');
header("Content-type:application/vnd.ms-excel;charset=UTF-8"); //application/vnd.ms-excel指定输出Excel格式
header("Content-Disposition:filename=表格文件名.xls"); //输出的表格名称

<?php

header("Content-Disposition:filename=表格文件名.xls");
$conn = mysql_connect("localhost","root","数据库暗码") or die("不能连接数据库");
mysql_select_db("数据库名",$conn);
mysql_query("set names 'UTF-8'");
$sql="select * from 表名 where 条件";
$result=mysql_query($sql);
echo "表头1t表头2t表头3n";
while($row=mysql_fetch_array($result)){
  echo $row[0]."t".$row[1]."t".$row[2]."n";

PHP教程
<?php
//载入PHPExcel类
require './phpexcel/PHPExcel.php';
//创建一个excel对象实例
$objPHPExcel = new PHPExcel();
//设置文档基本属性
$objProps = $objPHPExcel->getProperties();

$objProps->setDescription("Test document,generated by PHPExcel.");
$objProps->setKeywords("office excel PHPExcel");
$objProps->setCategory("Test");
//设置当前的sheet索引,用于后续的内容操作.
//一般只有在使用多个sheet的时候才需要显示调用.
//缺省情况下,PHPExcel会自动创建第一个sheet被设置SheetIndex=0
$objPHPExcel->setActiveSheetIndex(0);
//设置当前活动sheet的名称
$objActSheet = $objPHPExcel->getActiveSheet();
$objActSheet->setTitle('测试Sheet');
//设置单元格内容www.aspzz.cn
//这里的数据可以从数据库中读取,然后再做循环处理
$objPHPExcel->getActiveSheet()->SetCellValue('A1','a1');
$objPHPExcel->getActiveSheet()->SetCellValue('A2','a2');
$objPHPExcel->getActiveSheet()->SetCellValue('A3','a3');
$objPHPExcel->getActiveSheet()->SetCellValue('A4','a4');

//输出文档

//设置header头部信息,并输出到浏览器
//header('Content-Type: application/vnd.ms-excel');
//header("Content-Disposition:attachment; filename=demo.xls");
//header('Cache-Control: max-age=0');
//$objWriter->save('php://output');
//保存至某一位置
