代码如下:
<?php
$dirname = test1;
//mkdir($dirname);
//遍历一层目录
function listdir($dirname) {
$ds = opendir($dirname);
while($file = readdir($ds)) {
$path = $dirname.'/'.$file;
if(is_dir($file)) {
echo dir:.$file.<br>;
if($file != . && $file != ..) {
listdir($file);
}
}
else {
echo file:.$file . <br>;
}
}
}
function totdir($dirname) { //对listdir稍加修改
static $tot = 0;
$ds = opendir($dirname);
while($file = readdir($ds)) {
$path = $dirname.'/'.$file;
if(is_dir($file)) {
//echo dir:.$file.<br>;
if($file != . && $file != ..) {
$tot += totdir($file);
}
}
else {
//echo file:.$file . <br>;
$tot += filesize($path);
}
}
//返回总计
return $tot;
}
listdir($dirname);
echo totdir($dirname). bytes;
