function foldersize($path) {
$total_size = 0;
$files = scandir($path);
foreach($files as $t) {
if (is_dir(rtrim($path, '/') . '/' . $t)) {
if ($t<>"." && $t<>"..") {
$size = foldersize(rtrim($path, '/') . '/' . $t);
$total_size += $size;
}
} else {
$size = filesize(rtrim($path, '/') . '/' . $t);
$total_size += $size;
}
}
return $total_size;
}
function format_size($size) {
$mod = 1024;
$units = explode(' ','B KB MB GB TB PB');
for ($i = 0; $size > $mod; $i++) {
$size /= $mod;
}
return round($size, 2) . ' ' . $units[$i];
}
$SIZE_LIMIT = 5368709120; // 5 GB
$sql="select * from users order by id";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result)) {
$disk_used = foldersize("C:/xampp/htdocs/freehosting/".$row['name']);
$disk_remaining = $SIZE_LIMIT - $disk_used;
print 'Name: ' . $row['name'] . '<br>';
print 'diskspace used: ' . format_size($disk_used) . '<br>';
print 'diskspace left: ' . format_size($disk_remaining) . '<br><hr>';
}你知道为什么在脚本执行完成之前，处理器使用率会过高或达到100%吗？可以做些什么来优化它吗？或者有没有其他方法来检查文件夹和里面的文件夹大小？

以下是offered elsewhere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;

一个纯粹的php示例。
<?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];
}

function get_dir_size($directory){
$size = 0;
$files = glob($directory.'/*');
foreach($files as $path){
is_file($path) && $size += filesize($path);
is_dir($path) && $size += get_dir_size($path);
}
return $size;
