This function:
function GetTID($kid)
{
$a=$kid;
$conn = odbc_pconnect("$database", "$username", "$password");
$query = "select * from KontrahIO where KontrId2 = ".$kid;
$table = odbc_do($conn,$query);
$xi=1;
odbc_fetch_row($table);
while (odbc_fetch_row($table)) {
$tid[$xi]=odbc_result($table,9);
$a=$tid[$xi];
$xi++;
}
odbc_close($conn);
return $tid;
}

works but this one:

function GetTID($kid)
{
$database="Hetman";
$username="admin";
$password="pewnienie";
$conn = odbc_pconnect("$database", "$username", "$password");
$query = "select * from KontrahIO where KontrId2 = ".$kid;
$table = odbc_do($conn,$query);
$xi=1;
odbc_fetch_row($table);
while (odbc_fetch_row($table)) {
$tid[$xi]=odbc_result($table,9);
$a=$tid[$xi];
$xi++;
}
odbc_close($conn);
return $tid;
}

no... It's returning nothing
