Dir_size () is a function used to obtain the folder size. This function uses recursive methods. You need to call get_file_list () to obtain the list of all files in the folder. If a folder exists in the file list, call get_all_files () to obtain the file list in the folder. The size of the target folder is obtained.

SetupSize () is a unit that converts the size of the uploaded object to a file unit that is easy to read. It can be converted to Bytes, KB, MB, GB, TB, PB, EB, ZB, YB, and other units.

Column 2

The code is as follows: Copy code

<? Php

Function getDirSize ($ dir)
    {
$ Handle = opendir ($ dir );
While (false! ==( $ FolderOrFile = readdir ($ handle )))
        {
If ($ FolderOrFile! = "." & $ FolderOrFile! = "..")
            {
If (is_dir ("$ dir/$ FolderOrFile "))
                {
$ SizeResult + = getDirSize ("$ dir/$ FolderOrFile ");
                }
Else
                {
$ SizeResult + = filesize ("$ dir/$ FolderOrFile ");
                }
            }   
        }
Closedir ($ handle );
Return $ sizeResult;
    }

// Automatic unit conversion function
Function getRealSize ($ size)
    {
$ Kb = 1024; // Kilobyte
$ Mb = 1024 * $ kb; // Megabyte
$ Gb = 1024 * $ mb; // Gigabyte
$ Tb = 1024 * $ gb; // Terabyte
       
If ($ size <$ kb)
        {
Return $ size. "B ";
        }
Else if ($ size <$ mb)
        {
Return round ($ size/$ kb, 2). "KB ";
        }
Else if ($ size <$ gb)
        {
Return round ($ size/$ mb, 2). "MB ";
        }
Else if ($ size <$ tb)
        {
Return round ($ size/$ gb, 2). "GB ";
        }
Else
        {
Return round ($ size/$ tb, 2). "TB ";
        }
    }

Echo getRealSize (getDirSize (dirname ($ _ SERVER [SCRIPT_FILENAME])./include /));


?>

######################################## #################

// Function dirsize ($ dir)
//{
// $ Handle = opendir ($ dir );
// $ Size = 0;
// While ($ file = readdir ($ handle ))
//{
// If ($ file = ".") | ($ file = "..") continue;
// If (is_dir ("$ dir/$ file "))
// $ Size + = dirsize ("$ dir/$ file ");
// Else
// $ Size + = filesize ("$ dir/$ file ");
//}
// Closedir ($ handle );
// Return $ size;
//}
// $ Big = dirsize (dirname ($ _ SERVER [SCRIPT_FILENAME]). "/");
// Echo $ big;

The result is two digits after the decimal point.

$ Big * 1024 is measured in KB.
