PHP reports warning about invalid statement handle after I
use ibase_close() to close opened with ipbase_connect()
database connection. If I comment ibase_close that removes
this warning (all this code must be in function to get
warning,in plain use - there are no warnings in any case). I
think that it's a bug in cleanup code at shutdown.

<?
    first_connect();
 
function first_connect(){
    $dbh =
ibase_connect("localhost:/usr/interbase/data/db.gdb",
"login","password", none, 100, 3, "role"); 
    if (!$dbh)
    {
        echo "An error occured while connecting!!!\n";
        exit;
    }
    else
    {
        $username = "KIRILL";
        $qry = "SELECT * FROM GETUSERROLE('$username')";
        $sth = ibase_query ($dbh, $qry);
        while ($row = ibase_fetch_object ($sth)){}
        ibase_close($dbh);
    }
}
 
?>
