echo $_GET['categorie'];
if(isset($_GET['greater']))
        echo $_GET['greater'];
else 
    echo $_GET['smaller'];
echo $_GET['numar'];

$conn = oci_connect('student', 'STUDENT', 'localhost/XE');
    if( !$conn ) {
        $e = oci_error();
        trigger_error( htmlentities( $e['message'], ENT_QUOTES ), E_USER_ERROR );
    }

    $stid = oci_parse( $conn, "SELECT count(*) FROM nepal where ".$_GET['categorie']." ".$_GET['greater']." ".$_GET['numar']);
    if( !$stid ) {
        $e = oci_error( $conn );
        trigger_error( htmlentities( $e['message'], ENT_QUOTES ), E_USER_ERROR );
    }
    echo " ";
    echo oci_execute($stid);
