如何在PHP脚本中查看来自cpanel的电子邮件的文件夹或目录大小？

Question

$_SERVER['DOCUMENT_ROOT'] = /home/username/public_html

how to get /home/mail directory in PHP?

Answer 1

function folderSize ($dir)
{
    $size = 0;
    foreach (glob(rtrim($dir, '/').'/*', GLOB_NOSORT) as $each) {
        $size += is_file($each) ? filesize($each) : folderSize($each);
    }
    return $size;
}

echo folderSize('/home/username/mail/');

you have to check if that path is correct in your server, the example is for centos and cpanel
