PHP 8 on Ubuntu.

I’m trying to write a script that will go into a number of subdirectories and look for a .mp4 file, where I can then run some other code with exec() to create thumbnail images of the videos.

The problem begins where if I do something like this:

$directory = '.'; // This script lives in the same directory where the sub-directories are

$directories = glob($directory . '/*', GLOB_ONLYDIR);

foreach ($directories as $dir) {
    echo "Directory: $dir\n";
}

I might get the following output:

Directory: ./Are you ready for something
Directory: ./Yet another folder name
Directory: ./And one more

All of these directories have spaces in them. If I was then to try and cd into one of those directories:

foreach ($directories as $dir) {
    echo "Directory: $dir\n";

    exec('cd ' . $dir . "https://stackoverflow.com/");
}

It will error with

cd: ./Are: No such file or directory

This is because to cd into that directory I would actually need to do something like this, which adds backslashes where the spaces appear in the directory name

cd Are\ you\ ready\ for\ something\/

The output from glob doesn’t contain those backslashes so can’t be used directly. Is there any way around this?
