Answer 1

I suppose you should do it in controller, not in template.

You can use regex for that smth like this:

preg_replace('/[a-zA-Z.]/', '', $string);

If you're really need it to use in blade template, you can create some additional file with helper function, and use it anywhere you whant:

function filterFileName($string) {
    return preg_replace('/[a-zA-Z.]/', '', $string);
}

1. Create helpers.php file
2. Add your function filterFileName in it.
3. Add that file in composer.json and load it with composer dump-autoload
4. Now, you can use it in template:

{{ filterFileName($string) }}
