php 导出Excel

方法一【win下不乱码】

<?php 
header('Content-type: text/html; charset=utf-8');
header("Content-type:application/vnd.ms-excel;charset=UTF-8"); 
header("Content-Disposition:filename=test.xls"); //输出的表格名称
echo "ID\t";echo "奖品\t";echo "中奖时间\t\n";
//这是表格头字段 加\T就是换格,加\T\N就是结束这一行,换行的意思
$conn = @mysql_connect("127.0.0.1","root","123456");
	if (!$conn){
    die("连接数据库失败：" . mysql_error());
	}
	
	mysql_select_db("test", $conn);
	mysql_query("set names 'utf8'"); 
$result=mysql_query("SELECT a.dianhua,b.jiang,b.`jiangtime`  FROM `gouwu` as a ,`zhongjiang` as b   where a.openid=b.openid and  b.rid<5 ORDER BY `jiangtime` DESC");    

while($row=mysql_fetch_array($result)){
echo $row[0]."\t";echo $row[1]."\t";echo $row[2]."\t\n";
}
?>

方法二【Mac下不乱码】

<?php 
$datemin=$_GET['datemin'];
$datemax=$_GET['datemax'];
if (($datemin<0)or ($datemax<0)){
  echo "日期错误";
  exit;
}

$conn = @mysql_connect("127.0.0.1","root","123456");
	if (!$conn){
    die("连接数据库失败：" . mysql_error());
	}
$savename = date("Ymj").'顾客进出明细'; //导出excel文件名
$file_type = "vnd.ms-excel"; 
 $file_ending = "xls"; 
 header("Content-Type: application/$file_type;charset=utf-8"); 
 header("Content-Disposition: attachment; filename=".$savename.".$file_ending"); 
header("Pragma: no-cache"); 

/*查询数据库*/
	mysql_select_db("hyjcs_hongyujit", $conn);
	mysql_query("set names 'utf8'"); 
$sql = "SELECT a.`id`,a.`name` as 姓名,a.`dianhua` as 电话,a.`xiaoqu` as 位置,b.`jinchu` as 进出情况,b.tiwen as 体温,b.uptime as 更新时间 FROM `dengji`a,jinchumingxi b WHERE a.openid=b.openid and b.uptime >'".$datemin." 00:00:00' and b.uptime<'".$datemax." 23:59:59' ORDER BY b.`uptime`";
$result=mysql_query($sql); 

/*写入表字段名*/
for ($i = 0; $i < mysql_num_fields($result); $i++) { 
  
  echo iconv("utf-8","gbk",mysql_field_name($result,$i)) . "\t"; 
 // 标题转码

 } 
 echo "\n";

/*写入表数据*/
 $sep = "\t"; 
 while($row = mysql_fetch_row($result)) { 
  $data = ""; 
   for($i=0; $i<mysql_num_fields($result);$i++) { 
    if(!isset($row[$i])) 
     $data .= "NULL".$sep; //处理NULL字段
   elseif ($row[$i] != ""){
     $datmp=iconv("utf-8", "gbk",$row[$i]);
     $data .= $datmp.$sep; 
   }
    else 
     $data .= "".$sep; //处理空字段
  } 
  echo $data."\n"; 
 }
 ?>
