Delete All Files Except 'placeholder.png' in folder using Laravel

Question

So I'm trying to figure this all out here. I've seen this post below about how to delete all files within a directory, however I want to exclude my placeholder image from this deletion. I haven't come across the answer I'm looking for yet on SO, so this is just going to be a short and simple question.

Take a look at this SO question here: Laravel File Storage delete all files in directory

Answer 1

delete() accepts an array of files for deletion. Thus, one possible solution is listing the directory with a wildcard selector, then filter out your exclusion list from the array.

$filesForDelete = array_filter(glob("path/to/files/*"), function($file) {
    return false === strpos($file, 'placeholder.png');
});

Storage::delete($filesForDelete);

Of course, your filter expression may become better, broader, or just do the same thing in many other ways.

For example, you may create a helper function like this:

function deleteAllButFile($exclude)
{
    $filesForDelete = array_filter(glob("path/to/files/*"), function($file) use ($exclude) {
        return false === strpos($file, $exclude);
    });
    Storage::delete($filesForDelete);
}

// Call it like
deleteAllButFile('placeholder.png');

Or any other way you like. Up to your imagination.
