<?php
//计时开始
$time_start = getmicrotime();   
function getmicrotime()   
{   
list($usec, $sec) = explode(" ",microtime());   
return ((float)$usec + (float)$sec);   
}
//计时开始
set_time_limit(0);
header('Content-Type:text/html;charset=utf-8');
define('TUZWU_ROOT', str_replace("\\", '/', substr(dirname(__FILE__), 0)));
echo TUZWU_ROOT.'目录文件:<br>';
function checkdir($dirs)
{
$arrfile = glob($dirs);
foreach($arrfile AS $key => $val)
{
if(is_dir($val)) checkdir($val.'/*');
else
{
echo iconv('gbk','utf-8',$val).' MD5值 : '.md5_file($val).'<br>';
}
}
}
echo checkdir(TUZWU_ROOT.'/*');
//计时结束
$time_end = getmicrotime();   
printf ("[页面执行时间: %.2f毫秒]\n\n",($time_end - $time_start)*1000);
//计时结束
?>


执行结果如下:
