458
 
        *
459
 
        * Note arguments: comparied to substr - if offset or length are
460
 
        * not integers, this version will not complain but rather massages them
461
 
        * into an integer.
462
 
        *
463
 
        * Note on returned values: substr documentation states false can be
464
 
        * returned in some cases (e.g. offset > string length)
465
 
        * mb_substr never returns false, it will return an empty string instead.
466
 
        * This adopts the mb_substr approach
467
 
        *
468
 
        * Note on implementation: PCRE only supports repetitions of less than
469
 
        * 65536, in order to accept up to MAXINT values for offset and length,
470
 
        * we'll repeat a group of 65535 characters when needed.
471
 
        *
472
 
        * Note on implementation: calculating the number of characters in the
473
 
        * string is a relatively expensive operation, so we only carry it out when
474
 
        * necessary. It isn't necessary for +ve offsets and no specified length
