Any idea why the processor usage shoot up too high or 100% till the script execution is finish ? Can anything be done to optimize it? or is there any other alternative way to check folder and folders inside it size?
This question is related to
php
filesystems
The answer is
Even though there are already many many answers to this post, I feel I have to add another option for unix hosts that only returns the sum of all file sizes in the directory (recursively).
If you look at Jonathan's answer he uses the du command. This command will return the total directory size but the pure PHP solutions posted by others here will return the sum of all file sizes. Big difference!
What to look out for
When running du on a newly created directory, it may return 4K instead of 0. This may even get more confusing after having deleted files from the directory in question, having du reporting a total directory size that does not correspond to the sum of the sizes of the files within it. Why? The command du returns a report based on some file settings, as Hermann Ingjaldsson commented on this post.
The solution
To form a solution that behaves like some of the PHP-only scripts posted here, you can use ls command and pipe it to awk like this:
ls -ltrR /path/to/dir |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'
As a PHP function you could use something like this:
function getDirectorySize( $path )
{
if( !is_dir( $path ) ) {
return 0;
}
$path = strval( $path );
$io = popen( "ls -ltrR {$path} |awk '{print \$5}'|awk 'BEGIN{sum=0} {sum=sum+\$1} END {print sum}'", 'r' );
$size = intval( fgets( $io, 80 ) );
pclose( $io );
return $size;
}
function get_dir_size($directory){
$size = 0;
$files = glob($directory.'/*');
foreach($files as $path){
is_file($path) && $size += filesize($path);
is_dir($path) && $size += get_dir_size($path);
}
return $size;
}
if you are hosted on Linux:
passthru('du -h -s ' . $DIRECTORY_PATH)
It's better than foreach

It works perfectly fine .

foreach (glob(rtrim($dir, '/') . '/*', GLOB_NOSORT) as $each) {
$func_name = __FUNCTION__;
$size += is_file($each) ? filesize($each) : static::$func_name($each);
}
return $size;
}
Just another function using native php functions.
function dirSize($dir)
{
$dirSize = 0;
if(!is_dir($dir)){return false;};
$files = scandir($dir);if(!$files){return false;}
$files = array_diff($files, array('.','..'));
foreach ($files as $file) {
if(is_dir("$dir/$file")){
$dirSize += dirSize("$dir/$file");
}else{
$dirSize += filesize("$dir/$file");
}
}
return $dirSize;
}
NOTE: this function returns the files sizes, NOT the size on disk
I found this approach to be shorter and more compatible. The Mac OS X version of "du" doesn't support the -b (or --bytes) option for some reason, so this sticks to the more-compatible -k option.
$file_directory = './directory/path';
$output = exec('du -sk ' . $file_directory);
$filesize = trim(str_replace($file_directory, '', $output)) * 1024;
Returns the $filesize in bytes.

There are several things you could do to optimise the script - but maximum success would make it IO-bound rather than CPU-bound:
- Calculate
rtrim($path, '/')outside the loop. - make
if ($t<>"." && $t<>"..")the outer test - it doesn't need to stat the path - Calculate
rtrim($path, '/') . '/' . $tonce per loop - inside 2) and taking 1) into account. - Calculate
explode(' ','B KB MB GB TB PB');once rather than each call?

Regarding Johnathan Sampson's Linux example, watch out when you are doing an intval on the outcome of the "du" function, if the size is >2GB, it will keep showing 2GB.
Replace:
$totalSize = intval(fgets($io, 80));
by:
strtok(fgets($io, 80), " ");
supposed your "du" function returns the size separated with space followed by the directory/file name.

The same idea as Janith Chinthana suggested. With a few fixes:
- Converts
$pathto realpath - Performs iteration only if path is valid and folder exists
- Skips
.and..files - Optimized for performance
