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"; } }

$filename='文件名称';
  $filetitle='你的标题';
