PHP uses C syntax, not a BASIC syntax, so the "not equal" operator is != and
not <>
Also, for string comparisons, you should use strcmp, but when comparing to
an empty string or null, you should use empty() or isset(). So, your code
might look like this:
// note: isset will tell you if the "geocountry" value is set in the
REQUEST.
if (isset($_REQUEST["geocountry"])){
$_SESSION['geocountry']= $_REQUEST["geocountry"];
$_SESSION['geocountryId']=$_REQUEST["geocountry"];
}
