Renaming all files within different sub directories

I m trying to rename files to lowercase within a directory, however the problem I'm having is being able to scan the sub-directories for the files.

So in this case $app_dir is the main directory and the files I need to change exist within multiple sub-folders.

Heres my code so far:

$files = scandir($app_dir);
foreach($files as $key=>$name){
$oldName = $name;
$newName = strtolower($name);
rename("$app_dir/$oldName","$app_dir/$newName");
}

Thanks for your help.

Solution

  • If you are trying to lowercase all file names you can try this:

    Using this filesystem:

    Josh@laptop:~$ find josh
josh
josh/A
josh/B
josh/f1
josh/f2
josh/is
josh/is/awesome
josh/is/awesome/e
josh/is/awesome/t

    Code:

    <?php
$app_dir = 'josh';
$dir = new RecursiveDirectoryIterator($app_dir, FilesystemIterator::SKIP_DOTS);
$iter = new RecursiveIteratorIterator($dir);
foreach ($iter as $file) {
    if ($file != strtolower($file)) {
        rename($file, strtolower($file));
    }
}

    Results:

    Josh@laptop:~$ find josh
josh
josh/a
josh/b
josh/f1
josh/f2
josh/is
josh/is/awesome
josh/is/awesome/e
josh/is/awesome/t

    This code does not take into account uppercase letters in directories but that exercise is up to you.
