Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.

mb_substr() returns the portion of `str` specified by the `start` and `length` parameters.

mb_substr() performs multi-byte safe substr() operation based on number of characters. Position is counted from the beginning of `str`. First character's position is 0. Second character position is 1, and so on.

If `encoding` is omitted, internal encoding is assumed.

`encoding` is character encoding. If it is omitted, internal character encoding is used.
