PHP把表单中的数据写入到EXCEL

if($name!=null){
try{

    date_default_timezone_set('Etc/GMT-8');     //这里设置了时区
    $time= date("Y-m-d H:i:s");


    $fp = fopen("data.csv","a"); //打开csv文件，如果不存在则创建
    $data_1 = array($name,$cartype,$buycar,$phone,$email,$time,$carnumber);
    $data_1 = implode(",",$data_1); // 用 ' 分割成字符串
    $data_str =$data_1."\r\n"; //加入换行符
    $p=fwrite($fp,$data_str); // 写入数据
    //echo $p;
    if($p!=null&&$p!=""){
    	//echo "ok...";
    }else{
    	echo "<script>alert('提交失败!');location.href='index.php';</script>";
    }
    fclose($fp); //关闭文件句柄
    // echo "提交成功";

    echo "<script>alert('提交成功!');location.href='done.php';</script>";

   }catch(Exception $e){
	  echo 'Caught exception: ',  $e->getMessage(), "\n";
      echo "<script>alert('提交失败!');location.href='index.php';</script>";

   }
