PHP calculates the space occupied by files in a specified directory
In PHP, you can extend DirectoryIterator's getChildren() method through RecursiveDirectoryIterator to provide a method to access each element in the subdirectory. The following code obtains their temporary space by traversing all the files in the access directory.

$dir = new RecursiveDirectoryIterator('C:wamp');
$totalSize = 0;
foreach (new RecursiveIteratorIterator($dir) as $file) {
 $totalSize += $file- >getSize();
}
print "The total size is $totalSize.n";
?>
