PHP how to get size of all files in one directory?

Question

I want to get size of all files in one directory.Here is code that i have tried

$files=scandir(__DIR__,1);
echo $files[0]["size"];

This code saves all files in $files but it saves only its' names not sizes.

There's no built-in for this, you'd have to recursively iterate over the files and sum up each one's size. You're probably better off using a shell command like `du`. — Alex Howansky, Jul 10 '17 at 20:19
What is the desired result? One number - the total size of all files in the directory or an array (key = filename, value = size)? What about subdirectories? — Jirka Hrazdil, Jul 10 '17 at 20:20
@JiriHrazdil yes just one number the total size.There are no subdirecotires. — sakoaskoaso, Jul 10 '17 at 20:20
See [`RecursiveDirectoryIterator `](http://php.net/manual/en/class.recursivedirectoryiterator.php) — Alex Howansky, Jul 10 '17 at 20:21
If you're certain you never need to worry about subdirs, you can use [`DirectoryIterator`](http://php.net/manual/en/class.directoryiterator.php). — Alex Howansky, Jul 10 '17 at 20:22

you can try this:

function getDirSize($path)
{
    $fio = popen('/usr/bin/du -sb '.$path, 'r');
    $size = intval(fgets($fio,80));
    pclose($fio);
    return $size;
}

or

function getDirSize($path) {
    $size = 0;
    foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $file){
        $size+=$file->getSize();
    }
    return $size;
}
