0x00000050 computer blue screen code PHP code to obtain the size of a certain directory

The general idea of ​​the program is to use recursive rules to calculate how much space a directory occupies, and then write the space occupied value into a text file. Then as long as the txt file is accessed, you will know how much space is occupied, and there is no need to frequently obtain and read the disk, saving resources. . Every time the user uploads a file or deletes a file, the statistics will be recalculated. Of course, the statistical results can also be saved in the database.

Copy the code The 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 KAhMah functions:

Copy Code The code is as follows:

function get_real_size($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";
}
}

Usage Very simple:

Copy the code The code is as follows:

$size_zip=countDirSize("../zip/");
$size_zip=get_real_size($size_zip);

It’s that simple, haha .

Copy the code The 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 functions ***/
//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;
//If the user deletes or uploads a file, Re-get the directory size
if (action == "upload" || action == "delete") {
saveDirSize(userPath);
}
userDirSize = getDirSize(userPath)/1024;
echo "User: ".user;
echo "Space occupied: ".userDirSize;
?>

The above has introduced the 0x00000050 computer blue screen code. PHP obtains the code of a certain directory size, including the content of the 0x00000050 computer blue screen code. I hope it will be helpful to friends who are interested in PHP tutorials.
