First method:

$filename=&#39;文件名称&#39;;
  $filetitle=&#39;你的标题&#39;;
  if($_POST){
    set_time_limit(10000)；
    $title = &#39;&#39;;
    ini_set(&#39;memory_limit&#39;,&#39;300M&#39;);
    header(&#39;Content-Type: application/vnd.ms-excel;charset=utf-8&#39;);
    $name = $title.".xls";
    header(&#39;Content-Disposition: attachment;filename=&#39;.$name.&#39;&#39;);
    header(&#39;Cache-Control: max-age=0&#39;);
    $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(&#39;php://output&#39;, &#39;a&#39;);
    // 输出Excel列头信息 
    $head = array(&#39;ID&#39;);
    //字符替换
    $p_new_lines = array("\r\n", "\n","\t","\r","\r\n", "<pre class="brush:php;toolbar:false">","

","
","
","
"); $p_change_line_in_excel_cell = ''; foreach($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"; } }

    header(&#39;Content-Disposition: attachment;filename=&#39;.$name.&#39;&#39;);
    header(&#39;Cache-Control: max-age=0&#39;);
    echo &#39;<html xmlns:o="urn:schemas-microsoft-com:office:office"
