最近偶的网站越来越慢，不是脚本执行时间慢，是网络传输速度慢。
知道http1.1支持gzip编码的数据，所以试试将自己的页面压缩压缩...
（在php.ini可以设置，直接输出为gzip编码,不过没试过）

上网搜到一个gzdoc.php，改了改，让大家共同琢磨琢磨。
ob_start();//打开输出缓冲
ob_implicit_flush(0);//

//*****************************************************************//
//函数名:canGzip()
//作用:检查客户浏览器是否支持gzip,x-gzip编码
//参数:
//返回值:支持的编码类型"gzip", "x-gzip", 返回false代表不支持
//*****************************************************************//
function canGzip()
{
//if (headers_sent() || connection_status)
//return false;

if (strpos('King'.$_SERVER["HTTP_ACCEPT_ENCODING"], 'gzip') !== false)
return "gzip";

if (strpos('King'.$_SERVER["HTTP_ACCEPT_ENCODING"], 'x-gzip') !== false)
return "x-gzip";

return false;
}

//*****************************************************************//
//函数名:doGzipOut($level, $debug)
//作用:对输出缓冲的数据进行压缩并输出
//参数:$level代表压缩级别, 0 = 不压缩, 9 = 最大压缩率
// $debug代表是否输出调试信息, 1 = 输出, 0 = 不输出
//返回值:
//*****************************************************************//
function doGzipOut($level = 1, $debug = 0)
{
$ENCODING = canGzip();
if ($ENCODING)
{
echo "nn";
$contents = ob_get_contents();
