File name sanitizer
This is a way to sanitize a string to be used as file name or URL path etc. by removing unwanted characters or replacing them with a hyphen or similar.
It takes a string like:
Daily SimpliVity Backup 12/16/2018 02:00:215
and converts it into:
daily-simplivity-backup-12-16-2018-02-00-25

$file_name = preg_replace( '/[^a-z0-9]+/', '-', strtolower( $url ) );
