    Beschreibung

    mb_trim(string $string, string $characters = null, string $encoding = null): string

    • "\t" (ASCII 9 (0x09)), a tab.
    • "\n" (ASCII 10 (0x0A)), a new line (line feed).
    • "\r" (ASCII 13 (0x0D)), a carriage return.
    • "\0" (ASCII 0 (0x00)), the NUL-byte.
    • "\v" (ASCII 11 (0x0B)), a vertical tab.
