| 	*
 | |
| 	* Note arguments: comparied to substr - if offset or length are
 | |
| 	* not integers, this version will not complain but rather massages them
 | |
| 	* into an integer.
 | |
| 	*
 | |
| 	* Note on returned values: substr documentation states false can be
 | |
| 	* returned in some cases (e.g. offset > string length)
 | |
| 	* mb_substr never returns false, it will return an empty string instead.
 | |
| 	* This adopts the mb_substr approach
 | |
| 	*
 | |
| 	* Note on implementation: PCRE only supports repetitions of less than
 | |
| 	* 65536, in order to accept up to MAXINT values for offset and length,
 | |
| 	* we'll repeat a group of 65535 characters when needed.
 | |
| 	*
 | |
| 	* Note on implementation: calculating the number of characters in the
 | |
| 	* string is a relatively expensive operation, so we only carry it out when
 | |
| 	* necessary. It isn't necessary for +ve offsets and no specified length
