    #Regular Expression Pattern Tips:
    # I or IGNORECASE <=> (?i)      case insensitive matching
    # L or LOCALE <=> (?L)          make \w, \W, \b, \B dependent on the current locale
    # M or MULTILINE <=> (?m)       matches every new line and not only start/end of the whole string
    # S or DOTALL <=> (?s)          '.' matches ALL chars, including newline
    # U or UNICODE <=> (?u)         Make \w, \W, \b, and \B dependent on the Unicode character properties database.
    # X or VERBOSE <=> (?x)         Ignores whitespace outside character sets
