-    * @param int|null $length If given and is positive, it represents the length of the portion of string which is to

-     * stop replacing. If it is not given, then it will default to strlen( string ); i.e. end the replacing at the
-     * end of string. Of course, if length is zero then this function will have the effect of inserting replacement
-     * into string at the given start offset.
-    * @return string|array The result string is returned. If string is an array then array is returned.
