以下是其他地方提供的其他解决方案：
如果在Windows主机上：
<?
$f = 'f:/www/docs';
$obj = new COM ( 'scripting.filesystemobject' );
if ( is_object ( $obj ) )
{
$ref = $obj->getfolder ( $f );
echo 'Directory: ' . $f . ' => Size: ' . $ref->size;
$obj = null;
}
else
{
echo 'can not create object';
}
?>
否则，如果在Linux主机上：
<?
$f = './path/directory';
$io = popen ( '/usr/bin/du -sk ' . $f, 'r' );
$size = fgets ( $io, 4096);
$size = substr ( $size, 0, strpos ( $size, "\t" ) );
pclose ( $io );
echo 'Directory: ' . $f . ' => Size: ' . $size;
?>

function GetDirectorySize($path){
$bytestotal = 0;
$path = realpath($path);
if($path!==false && $path!='' && file_exists($path)){
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS)) as $object){
$bytestotal += $object->getSize();
}
}
return $bytestotal;
}
与詹妮丝·金塔纳（Janith Chinthana）提出的想法相同。有一些修复：
转换$path为realpath
仅当路径有效且文件夹存在时才执行迭代
跳过.和..文件
性能优化

一个纯PHP的例子。
<?php
$units = explode(' ', 'B KB MB GB TB PB');
$SIZE_LIMIT = 5368709120; // 5 GB
$disk_used = foldersize("/webData/users/vdbuilder@yahoo.com");
$disk_remaining = $SIZE_LIMIT - $disk_used;
echo("<html><body>");
echo('diskspace used: ' . format_size($disk_used) . '<br>');
echo( 'diskspace left: ' . format_size($disk_remaining) . '<br><hr>');
echo("</body></html>");
function foldersize($path) {
$total_size = 0;
$files = scandir($path);
$cleanPath = rtrim($path, '/'). '/';
foreach($files as $t) {
if ($t<>"." && $t<>"..") {
$currentFile = $cleanPath . $t;
if (is_dir($currentFile)) {
$size = foldersize($currentFile);
$total_size += $size;
}
else {
$size = filesize($currentFile);
$total_size += $size;
}
}
}
return $total_size;
}
function format_size($size) {
global $units;
$mod = 1024;
for ($i = 0; $size > $mod; $i++) {
$size /= $mod;
}
$endIndex = strpos($size, ".")+3;
return substr( $size, 0, $endIndex).' '.$units[$i];
}
?>
