0x00000050 Computer blue Screen code PHP get a directory size code

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 the Code code 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 the Code code 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 the Code code as follows:

$size _zip=countdirsize (". /zip/");
$size _zip=get_real_size ($size _zip);

It's so simple, hehe.

Copy the Code code 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;
?>

The above describes the 0x00000050 computer blue screen code PHP to get a directory size code, including the 0x00000050 computer blue screen code content, I hope to be interested in PHP tutorial friends helpful.
