如何在 PHP 中获取目录大小
2022-08-30 08:39:06
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>';
}
任何想法为什么处理器使用率飙升太高或100%直到脚本执行完成?可以做任何事情来优化它吗?或者有没有其他替代方法来检查文件夹和文件夹的大小?
