1、生成excel表格

<?php
header("content-type:text/html;charset=utf-8");
$dsn = "mysql:dbname=news;host=127.0.0.1";
$user = "root";
$pwd = "";
$pdo = new PDO($dsn,$user,$pwd);
//$sql = "select id,name.content,descs from brand";
$res = $pdo->query("select id,name,content,descs from brand");
$arr = $res->fetchAll(PDO::FETCH_ASSOC);
//$res = $pdo->exec("select id,name,content,descs from brand");
//$data = $res->execute();
//$arr = $res->fetchAll(PDO::FETCH_ASSOC);
//print_r($arr);die;
//引入类文件
require_once './Classes/PHPExcel.php';
require_once './Classes/PHPExcel/IOFactory.php';
require_once './Classes/PHPExcel/Reader/Excel5.php';

//创建新的PHPExcel对象
$objPHPExcel = new PHPExcel();
$objProps = $objPHPExcel->getProperties();
//设置表头
//ord():ord() 函数返回字符串第一个字符的 ASCII 值。语法 ord(string) 参数描述 string 必需。要从中获得 ASCII 值的字符串
$i = 0;
foreach($arr as $k=>$v){
   //print_r($v);die;
   if($i<1){
       $obj=array_keys($v);//array_keys() 函数返回包含数组中所有键名的一个新数组
       //print_r($obj);die;
       $key = ord("A");
       //print_r($key);die;
       foreach($obj as $ke=>$va){
           //print_r($va);die;
           $colum = chr($key);//输出excel表格中的行的（ABCD....）,如果显示B,则循环$key+1,
           //print_r($colum);//获取excel表格中的行的ABCD
           $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.'1', $va);//setCellValue()单元格赋值;
           $key+=1;
       }
   }
   $i++;
}

    $column = 2;
    $objActSheet = $objPHPExcel->getActiveSheet();
   //print_r($objActSheet);die;
    foreach($arr as $key => $rows){ //行写入
       //print_r($rows);die;
        $span = ord("A");
        foreach($rows as $keyName=>$value){// 列写入
           //print_r($value);die;//获取本条数据的id
            $h = chr($span);
           //print_r($h);die;
            $objActSheet->setCellValue($h.$column, $value);
            $span++;
        }
        $column++;
    }

    //生成excel文件
   //$fileName="excel.xls";
   $fileName = iconv("utf-8", "gb2312", "shengcheng.xls");
   //重命名表
   $objPHPExcel->getActiveSheet()->setTitle('Simple');
   //设置活动单指数到第一个表,所以Excel打开这是第一个表
   $objPHPExcel->setActiveSheetIndex(0);
   //将输出重定向到一个客户端web浏览器(Excel2007)
      header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
      header("Content-Disposition: p_w_upload; filename=\"$fileName\"");
      header('Cache-Control: max-age=0');
      $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
      $objWriter->save('php://output'); //文件通过浏览器下载
      exit;
?>

2、将生成的execl表格的数据入库

2.1、首先写一个form表单
<META NAME="" CONTENT="" charset="utf-8">
<form name="frm1" enctype="multipart/form-data" action="daoru.php" method="post">
<input name="filename" type="file" /><input name="submit" type="submit" value="上传" />
</form>

2.2、通过form 表单跳到指定的目录

<?php
header("content-type:text/html;charset=utf-8");

session_start();
//全局变量
$succ_result=0;
$error_result=0;
$file=$_FILES['filename'];
$max_size="2000000"; //最大文件限制（单位：byte）
$fname=$file['name'];
$ftype=strtolower(substr(strrchr($fname,'.'),1));
//文件格式
$uploadfile=$file['tmp_name'];
if($_SERVER['REQUEST_METHOD']=='POST'){
     if(is_uploaded_file($uploadfile)){
          if($file['size']>$max_size){
         echo "Import file is too large";
         exit;
         }
          if($ftype!='xls'){
         echo "Import file type is error";
          exit;
         }
     }else{
     echo "The file is not empty!";
      exit;
     }
}
//连接mysql数据库
$dsn = "mysql:dbname=news;host=127.0.0.1";
$user = "root";
$pwd = "";
$pdo = new PDO($dsn,$user,$pwd);

//调用phpexcel类库
/*
require_once 'phpexcel.php';
require_once 'PHPExcel\IOFactory.php';
require_once 'PHPExcel\Reader\Excel5.php';
*/
//引入类文件
require_once './Classes/PHPExcel.php';
require_once './Classes/PHPExcel/IOFactory.php';
require_once './Classes/PHPExcel/Reader/Excel5.php';

$objReader = PHPExcel_IOFactory::createReader('Excel2007');//use excel2007 for 2007 format
$objPHPExcel = $objReader->load($uploadfile);
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumn = $sheet->getHighestColumn(); // 取得总列数
$arr_result=array();
$strs=array();

for($j=2;$j<=$highestRow;$j++)
{
    unset($arr_result);
    unset($strs);
for($k='A';$k<= $highestColumn;$k++)
    {
     //读取单元格
@$arr_result .= $objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue().',';
    }
$strs=explode(",",$arr_result);
$sql="insert into brand(id,name,content,descs) values ($strs[0],'$strs[1]','$strs[2]','$strs[3]')";
echo $sql."<br/>";
// mysql_query("set names utf8");
$result=$pdo->exec($sql) or die("执行错误");

// $insert_num=mysql_affected_rows();
if($result>0){
        $succ_result+=1;
    }else{
        $error_result+=1;
   }

}

echo "插入成功".$succ_result."条数据！！！<br>";
echo "插入失败".$error_result."条数据！！！";

?>
