I'm a beginner with php and i'm following up after a programmer that tried to install the geoip php api on our website(but not quite successfully). I'm confused about what he was trying to do with this piece of code, specifically the following portion: if ($_REQUEST["geocountry"]<>"") short context: if ($_REQUEST["geocountry"]<>""){ $_SESSION['geocountry']= $_REQUEST["geocountry"]; $_SESSION['geocountryId']=$_REQUEST["geocountry"]; } I realize this is probably very simple, but I can't seem to find the answer. thank you in advance,
