mb_rtrim — Strip whitespace (or other characters) from the end of a string

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

Performs a multi-byte safe rtrim() operation, and returns a string with whitespace (or other characters) stripped from the end of string.

Without the second parameter, rtrim() will strip these characters:

" " (ASCII 32 (0x20)), an ordinary space.
"\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.

string: The input string.
characters: Optionally, the stripped characters can also be specified using the characters parameter. Simply list all characters that need to be stripped. With .. it is possible to specify an incrementing range of characters.
encoding: The string encoding.

Returns the modified string.
