[PHP] Help me to find md5 hash for a directory

[Subhash]

Can any one help me to find the md5 hash for a whole directory. I want this to make a automatic backup program in php.
Plz help me, If you can write a function to do that then it will be better.
:confused4

Something like this

function MD5Dir($dir) {

    $dir2 = opendir($dir);
        
    $files = readdir($dir2);

   closedir($dir2);

    $return = md5($files);

return $return;

}

I DON'T GUARENTEE THIS CODE TO WORK AS IT IS UNTESTED

Thank's for your effort.
But I think this will not take the md5 hash of the file contents, not also proceeds the subdirectories and does't has any option to work on directory structure.
However I manged to created a function in which it takes the hash of directory names, file names, proceed to subdirectories, includes hash of every file contents and holds the whole directory and file structure.

But yours one is also good, thanks for your concern.
