Hi, I just need to take the requested domain $rd and store in a variable that domain but with . replaced by _: sip.domain.org -> sip_domain_org This is because I want tables in MySQL containing the domain name but MySQL don't allow . in table name. So now, what should I do for that? I really thought "textops" could help me but I don't see a function to replace text and store it in a variable. I see "replace()" and "subst()" but they seem to exist for replacing text in the SIP message "on the fly", that is not that I'm looking for. Any suggestion? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
