mb_substr — Get part of string

### Description

string mb_substr ( string `$str` , int `$start` [, int `$length` [, string `$encoding` ]] )

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.
