复制代码 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\";

?>
