[OpenSIPS-Users] For-Each Example

[Bogdan-Andrei Iancu]

Hi,

If you have an AVP holding multiple value (instances), you can iterate 
through all of them as:

$var(n) = 0;
while ( $(avp(my_avp)[$var(n)]) != NULL ) {
     xlog("value of my avp on position $var(n) is 
$(avp(my_avp)[$var(n)]) \n");
     $var(n) = $var(n) + 1 ;
}
