PHP get code for a directory size _php tutorial

The approximate program idea is to use the recursive rules to calculate the amount of space occupied by the directory, and then the value of the space to write into the text file, so long as the access to the TXT file will know how much space occupied, do not have to read the disk frequently, save resources. Each time a user uploads a file or deletes a file, it is re-counted. Of course, you can also save the statistical results in the database.
Copy CodeThe code is as follows:
function Countdirsize ($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;
}

Convert bytes to normal K-m functions such as:
Copy CodeThe code is as follows:
function Get_real_size ($size) {

$KB = 1024; Kilobyte
$MB = 1024x768 * $KB; Megabyte
$GB = 1024x768 * $MB; Gigabyte
$TB = 1024x768 * $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 ";
}
}

The usage is simple:
Copy CodeThe code is as follows:
$size _zip=countdirsize (". /zip/");
$size _zip=get_real_size ($size _zip);

It's so simple, hehe.

Copy CodeThe code is as follows:
/**
* File:fetch User Directory use size
* Author:heiyeluren
* Create:2005-9-19 16:20
* Modifed:2005-9-19 16:41
*/

/*** Basic Function ***/

Calculate Directory Size
function Countdirsize (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;
}

Save user File Size
function Savedirsize (userdir)
{
Userdirsize = Countdirsize (Userdir);
if (!FP = fopen (userdir. ") /dir_size.txt "," w+ ")) {
Die ("Open file failed");
} else {
Fwrite (FP, dirsize);
}
}

Get the size of the user directory
function Getdirsize (userdir)
{
user = Addslashes (userdir);
Sizefile = Userdir. " /dir_size.txt ";
if (!FP = fopen (Sizefile, "R") {
return 0;
} else {
Dirsize = fread (FP, FileSize (Sizefile));
}
return dirsize;
}
/*** Call Instance ***/
user = "Heiyeluren";
UserPath = "./user/". User;

Re-fetch the directory size if the user performs a delete or upload file
if (action = = "Upload" | | action = = "Delete") {
Savedirsize (UserPath);
}

Userdirsize = Getdirsize (userpath)/1024;
echo "User:". User;
echo "Occupy space:". userdirsize;
?>
