PHP将mysql数据库导出为excel表

方法一,利用fputcsv

 代码如下 复制代码


// 输出Excel文件头,可把user.csv换成你要的文件名
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="user.csv"');
header('Cache-Control: max-age=0');

// 从数据库中获取数据,为了节省内存,不要把数据一次性读到内存,从句柄中一行一行读即可
$sql = 'select * from tbl where ……';
$stmt = $db->query($sql);

// 打开PHP文件句柄,php://output 表示直接输出到浏览器
$fp = fopen('php://output', 'a');

// 输出Excel列名信息
$head = array('姓名', '性别', '年龄', 'Email', '电话', '……');
foreach ($head as $i => $v) {
// CSV的Excel支持GBK编码,一定要转换,否则乱码
$head[$i] = iconv('utf-8', 'gbk', $v);
}

// 将数据通过fputcsv写到文件句柄
fputcsv($fp, $head);

// 计数器
$cnt = 0;
// 每隔$limit行,刷新一下输出buffer,不要太大,也不要太小
$limit = 100000;

// 逐行取出数据,不浪费内存
while ($row = $stmt->fetch(Zend_Db::FETCH_NUM)) {

$cnt ++;
if ($limit == $cnt) { //刷新一下输出buffer,防止由于数据过多造成问题
ob_flush();
flush();
$cnt = 0;
}

foreach ($row as $i => $v) {
$row[$i] = iconv('utf-8', 'gbk', $v);
}
fputcsv($fp, $row);
}

方法二,直接在浏览器用header输出csv格式的数据

 代码如下 复制代码

/*连接数据库*/
$DB_Server = "localhost";
$DB_Username = "root";
$DB_Password = "123456";
$DB_DBName = "mydb";  //目标数据库名
$DB_TBLName = "mytable";  //目标表名
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect.");
mysql_query("Set Names 'utf8'");

$savename = date("YmjHis"); //导出excel文件名
$file_type = "vnd.ms-excel";
$file_ending = "xls";
header("Content-Type: application/$file_type;charset=utf8");
header("Content-Disposition: attachment; filename=".$savename.".$file_ending");
//header("Pragma: no-cache");

/*写入备注信息*/
$now_date = date("Y-m-j H:i:s");
$title = "数据库名:$DB_DBName,数据表:$DB_TBLName,备份日期:$now_date";
echo("$titlen");

/*查询数据库*/
$sql = "Select * from $DB_TBLName";
$ALT_Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database");
$result = @mysql_query($sql,$Connect) or die(mysql_error());

/*写入表字段名*/
for ($i = 0; $i < mysql_num_fields($result); $i++) {
 echo mysql_field_name($result,$i) . ",";
}
echo "n";

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

例3,第二个差不多了

 代码如下 复制代码


//搜索
    $start_time = strtotime($start_date);
    $end_time = strtotime($end_date);
    $sql = "select a.*,b.order_amount,b.money_paid from ".$ecs->table('invoice')." as a ".
                " left join ".$ecs->table('order_info')." as b on a.order_id=b.order_sn".
                " where a.add_time >=".$start_time." and a.add_time <=".$end_time." ";
    $temp_list = $db->getAll($sql);

    if($temp_list){//有数据
        $Html=''.chr(13).chr(10);
        $Html.='


                           
                                   
                                   
                           
                           
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                           ';
            //取得符合条件的数组
            for($i=0;$i                  $temp_i = $i+1;
                 if($temp_list[$i][order_amount]==0){
                     $temp_money = $temp_list[$i][money_paid];
                 }else{
                     $temp_money = $temp_list[$i][order_amount];
                 }

                 $temp_time = date('Y-m-d', $temp_list[$i]['add_time']);
                 $Html.='


                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                                    
                           ';
             }
             $Html.='
时间:'.$start_date.'~'.$end_date.'

'.$temp_i.''.$temp_list[$i][type_name].''.$temp_list[$i][top].''.$temp_list[$i][content].''.$temp_list[$i][order_id].''.$temp_money.''.$temp_time.''.$temp_list[$i][user_name].''.$temp_list[$i][mobile].' '.$temp_list[$i][tel].' '.$temp_list[$i][address].'
';
             $Html.='';
             $mime_type = 'application/vnd.ms-excel';
             header('Content-Type: ' . $mime_type);
             header('Content-Disposition: attachment; filename="invoice.xls"');
             header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
             header('Pragma: public');
            echo $Html;

有时excel会自动把数字转换格式,于是有些手机号码,身份证之类的就乱了,因此可以在导出时,先定义好

 代码如下 复制代码

'.$temp_list[$i][order_id].'
