i have functions , db connection in external files included.

enter image description here

this image of table, don't know if right table structure inbox.

best way move condition (checking if equal my_id mysql query, , let resulting variable "users"). , end of query, can add;

group users

which make sure pull distinct "users"

you can incorporate condition mysql using if element, i.e.

select if(msg_from = '$my_id', msg_to, msg_from) users
