Recursive Chmod in php

recursechmod.php

<?php
    function recursiveChmod ($path, $filePerm=0644, $dirPerm=0755) {
        // Check if the path exists
        if (!file_exists($path)) {
            return(false);
        }
 
        // See whether this is a file
        if (is_file($path)) {
            // Chmod the file with our given filepermissions
            chmod($path, $filePerm);
 
        // If this is a directory...
        } elseif (is_dir($path)) {
            // Then get an array of the contents
            $foldersAndFiles = scandir($path);
 
            // Remove "." and ".." from the list
            $entries = array_slice($foldersAndFiles, 2);
 
            // Parse every result...
            foreach ($entries as $entry) {
                // And call this function again recursively, with the same permissions
                recursiveChmod($path."/".$entry, $filePerm, $dirPerm);
            }
 
            // When we are done with the contents of the directory, we chmod the directory itself
            chmod($path, $dirPerm);
        }
 
        // Everything seemed to work out well, return true
        return(true);
    }

Hi, there is a bug in this code (I have suffered it :P)
If you have a directory with a filename with a symbol like dollar ($) in the begining you will be lost in an infinite loop. The reason is that a file like this goes before "." and ".." when you do scandir. By this way, using array_slice you will remove only this file (for example $testfile.html) and not "." directory. You will get paths like "directory./././././././" until time execution limit

Awesome, thanks :

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();
