This article will show you how to get the folder size in php. we will recursively list the files and use filesize to calculate the file size and display it.
| The code is as follows: |

// Get the folder size
Function dir_size ($ dir ){
If (! Preg_match ('#/$ #', $ dir )){
$ Dir. = '/';
}
$ Totalsize = 0;
// Call the file list
Foreach (get_file_list ($ dir) as $ name ){
$ Totalsize + = (@ is_dir ($ dir. $ name )? Dir_size ("$ dir $ name /"):
(Int) @ filesize ($ dir. $ name ));
}
Return $ totalsize;
}
// Obtain the file list
Function get_file_list ($ path ){
$ F = $ d = array ();
// Obtain all objects
Foreach (get_all_files ($ path) as $ name ){
If (@ is_dir ($ path. $ name )){
$ D [] = $ name;
} Else if (@ is_file ($ path. $ name )){
$ F [] = $ name;
}

Natcasesort ($ f );

}
}
Closedir ($ hndl );

}
// Conversion Unit

}
$ Sizename = array ("Bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB ", "YB ");
Return round ($ size/pow (1024, ($ I = floor (log ($ size, 1024), 2). $ sizename [$ I];
}
// Directory

// Display the file list

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.

| The code is as follows: |
|
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 /));

The result is two digits after the decimal point.
$ Big * 1024 is measured in KB.
