I do this:
<?
$_memo = ifx_create_char($memo);
$char_id_array[]=$_memo;
$query_string='INSERT INTO news (product_date, header, memo) values (CURRENT, "'.$header.'", ? )';
$res_id = ifx_prepare($query_string, $conn_id, $charidarray);
ifx_do($res_id));
?>
What is a reason to this construction not works?
