Trong bài viết dưới dây vHost sẽ hướng dẫn quý khách sử dụng PHP Script để montior dung lượng disk sử dụng phân vùng root trên VPS hoặc Server, đây là chỉ một ví dụ quý khách có thể monitor bất kì vấn đề gì trên Server của mình với PHP Script Để có thể sử dụng PHP Script monitor dung lượng disk hoặc các vấn đề khác cần phải chuẩn bị những thứ cơ bản sau:
Mọi PHP Script tạo ra để monitor phải trả về 3 biến chuỗi json sau: + result: true hoặc false, tương ứng với kết quả test Đoạn Script trên sẽ trả về result=false tương ứng với kết quả trả về trên Server Monitor là fail nếu dung lượng disk sử dụng trên phân vùng root lớn hơn 2%, và ngược lại với result=true kết quả trên Server Monitor sẽ là Pass Sau khi đã tạo PHP Script và có thể truy cập URL thông qua trình duyệt ở đây vHost tạo với URL sau //103.232.120.135/serverstatus.php?key=rootpath, cần phải tạo một check như bên dưới để monitor, thông tin chi tiết về cách tạo Check quý khách có thể tham khảo tại link //docs.vhost.vn/article.php?id=179 Mọi yêu cầu cần được hỗ trợ và giải đáp xin vui lòng liên hệ lại vHost Email: Hotline: 19006806 Website: //vhost.vn/ |

I have a domain name like 'mydomain.com'. I want to check how much space available on server with this domain name with the help of php. Like for our hard drive we use disk_total_space["C:"];. Can anyone help me to get the solution.

Depending on the structure of the file system you can use something like the following for Linux hosts:
$df = round[disk_free_space["/var/www"] / 1024 / 1024 / 1024];
print["Free space: $df GB"];
Or in your case it sounds like you're running on Windows so:
$df = round[disk_free_space["C:"] / 1024 / 1024 / 1024];
print["Free space: $df GB"];

The main function is used to get space available is same as above said. you have to use disk_free_space[]. but the different is to know the server path. And put it in braces.

[PHP 4 >= 4.1.0, PHP 5, PHP 7, PHP 8]
disk_free_space — Returns available space on filesystem or disk partition
Description
disk_free_space[string $directory]: float|false
Parameters
directoryA directory of the filesystem or disk partition.
Note:
Given a file name instead of a directory, the behaviour of the function is unspecified and may differ between operating systems and PHP versions.
Return Values
Returns the number of available bytes as a float or false on failure.
Examples
Example #1 disk_free_space[] example
Notes
Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

Transformation is possible WITHOUT using loops:

$si_prefix = array[ 'B', 'KB', 'MB', 'GB', 'TB', 'EB', 'ZB', 'YB' ];
you are missing the petabyte after terabyte
'B', 'KB', 'MB', 'GB', 'TB', 'EB', 'ZB', 'YB'
should look like
'B', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'

Nice, but please be aware of the prefixes.
SI specifies a lower case 'k' as 1'000 prefix.
It doesn't make sense to use an upper case 'K' as binary prefix,
while the decimal Mega [M and following] prefixes in SI are uppercase.
Furthermore, there are REAL binary prefixes since a few years.
Do it the [newest and recommended] "IEC" way:
KB's are calculated decimal; power of 10 [1000 bytes each]
KiB's are calculated binary; power of 2 [1024 bytes each].
The same goes for MB, MiB and so on...
Feel free to read:

Another easy way to convert bytes to human readable sizes would be this:
It simply takes the $Bytes and divides it by 1024 bytes untill it's no longer over or equal to 1024, meanwhile it increases the $Index to allocate which suffix belongs to the return [adding 'bytes' to the end to save some space].
You can easily modify it so it's shorter, but I made it so it's more clearer.

This is not documented yet.
If $directory is invalid, then disk_free_space[] will return false and ALSO throw a Warning: "disk_free_space[]: No such file or directory"

With respect to Linux filesystems, I'll point out that this function returns the space available in the current volume or mountpoint, not the total physical disk space. That is, this function used on the '/root' volume shows the free space in /root, which is different from '/home', and so on.

On Windows, this also works with distant files, by using their full network path.
For instance, this will give the % of free disk space on the share "dir" from remote host "server" :
It can also work with drive letters mapped to a network path in certain cases.
