[OpenSIPS-Users] Anyway to count the numbers of entires in a AVP?

[Brad Bendy]

String function would be nice, but with Brett's suggested work around I
got it working, might even be faster then if we had string functions?

I think as more people want to make custom LCR implementations and
various things these type of functions will come up more im sure. I
think with the addition of db_http this will start coming up more, I
know myself and few others were even thinking of using that for a LCR
base. We ended up making a custom memcached program to do all our LCR
and return data to OpenSIPS which in turn is a CSV.

All of the ones Brett listed im sure would great features to add!
