第一种方法:

$filename='文件名称';
  $filetitle='你的标题';
  if($_post){
    set_time_limit(10000);
    $title = '';
    ini_set('memory_limit','300m');
    header('content-type: application/vnd.ms-excel;charset=utf-8');
    $name = $title.".xls";
    header('content-disposition: attachment;filename='.$name.'');
    header('cache-control: max-age=0');
    $where = "1=1";
    $sql = "";
    $query = db::query($sql);
    // 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列头信息 
    $head = array('id');
    //字符替换
    $p_new_lines = array("\r\n", "\n","\t","\r","\r\n", "<pre>","</pre>","<br>","</br>","<br/>");
    $p_change_line_in_excel_cell = '';

    foreach($head as $v){
      echo iconv('utf-8','gb2312',$v) . "\t";
    }
    echo "\n";
    // 计数器 
    $cnt = 0;
    // 每隔$limit行,刷新一下输出buffer,节约资源 
    $limit = 100000;
    // 逐行取出数据,节约内存
    while ($res = mysql_fetch_assoc($query)) {
      $cnt ++;
      if ($limit == $cnt) { //刷新一下输出buffer,防止由于数据过多造成问题 
        ob_flush();
        flush();
        $cnt = 0;
      } 
      echo trim($res['id']). "\t";
      echo "\n";
    }
