Hello,

I think both statements should be work similar. There used to be some special cases regarding evaluation of function return values in if-statements, but this is not the case you are referring to below. I have not tested it if this is still the case. It was discussed e.g. here https://kamailio.org/mailman3/hyperkitty/list/sr-users@lists.kamailio.org/th...

Cheers,

Henning

Hi All,

Just to add some context to my previous question: I'm trying to understand the difference between assigning the return value of a function to a variable directly vs assigning the “$rc” value to a variable after the function has run.

Rereading my initial email, I hope this makes my question clearer 🤣🤣

Thanks again, Joel

I have a simple doubt: are these snippets the same?

One:

secf_check_country($hdr(X-SRC-IP-CC)); $var(secf_cc_rc) = $rc; if ($var(secf_cc_rc) == -2) { ...

Two:

$var(secf_cc_rc) = secf_check_country($hdr(X-SRC-IP-CC)); if ($var(secf_cc_rc) == -2) { ...

They both seem to work, the docs say to use option -one-. In case they do the same, is there a reason I should pick one over the other? Or is this purely cosmetic?

Thanks, Joel.
