const BYTES_IN_GIGABYTE = 1024*1024*1024;
$total_space_bytes = disk_total_space("/");
$free_space_bytes = disk_free_space("/");
$total_space_gb = floor($total_space_bytes / BYTES_IN_GIGABYTE);
$free_space_gb = floor($free_space_bytes / BYTES_IN_GIGABYTE);
echo "总空间: $total_space_gb GB\n"; // 总空间: 465 GB
