[Users] strip_tail() string length?

I'm wondering what the easiest method would be to grab how long the RURI

is and strip based on that information... or would I have to actually use regex, or is there an easier STRLEN() or LENGTH() operation? Any ideas, or is this something that could be implemented? Thanks.

i too have been thinking that regex is an overkill for tests like this:

if (uri=~"^sip:+") ...

a php like substr function might be faster. so instead of the above or

i.e. strip_tail(strlen($ru) - 2); ... or something like such.

how about

if (substr(uri, 0, 5) == "sip:+") ...

or

substr($ru, -2, 2)

by the way, i didn't notice == operator in the summary. should i write the above if as

switch(substr(uri, 0, 5)) { case "sip:+": ... default: ... }

instead or is == supported?
