Nice script. Thanks for sharing. :-)
I would like to share a library I have coded with the same goal.

Example of usage:

<?php

use MathiasReker\PhpChmod\Scanner;

require __DIR__ . '/vendor/autoload.php';

(new Scanner())
    ->setDefaultFileMode(0644)
    ->setDefaultDirectoryMode(0755)
    ->setExcludedFileModes([0400, 0444, 0640])
    ->setExcludedDirectoryModes([0750])
    ->scan([__DIR__])
    ->fix();
