I once had an app which needed to generate long continuous ranges of alpha codes. But even then I did not implement -- in PHP userland. I think if there is a need for --, each application would need its own "correct" behaviour. AAA-- may be AA or ZZ or ZZZ or ZZ0 or ZZ9 or even 0ZZ depending on use case. If there is a reason to do this in C rather than PHP userland code, it's probably best fit in an extension. -- Ralf Lang Linux Consultant / Developer Tel.: +49-170-6381563 Mail: l...@b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg / http://www.b1-systems.de GF: Ralph Dehner / Unternehmenssitz: Vohburg / AG: Ingolstadt,HRB 3537
