Daniel, the '<>' syntax is perfectly valid PHP, plus you haven't actually
answered the question.
If you supply a parameter in the URL, i.e. 'www.mysite.com/geocountry=uk'
then information is made available in an array called '$_REQUEST'.
The specific parameter is accessed using the key name, in this case
'geocountry'.
So, the statement is saying, did a parameter called geocountry get passed in
the URL. If it was, then load it into a session variable called 'geocountry'
and 'geocountryId' :-
if ($_REQUEST["geocountry"] <> "") {
$_SESSION['geocountry']= $_REQUEST["geocountry"];
$_SESSION['geocountryId']=$_REQUEST["geocountry"];
}
As Daniel pointed out, you should also use isset() to avoid a PHP warning
message, and is also better programming.
Rob.

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:
