Here is the code segment that gives me problems:
(simplified)

$conn_id = odbc_connect($db_name, $user, $pass);
$stmt = odbc_prepare($conn_id, "INSERT INTO
          table (value1, value2) VALUES (?, ?)");
$data = array('test1', 'test2');

odbc_execute($stmt, &$data);


When using an Oracle database server, this produces the following error message:

Warning: SQL error: [Oracle][ODBC Oracle Driver]SQLBindParameter has not been called for parameter #2., SQL state 07001 in SQLExecute in ...

I tried to use Access first, and got the same error (07001).
I cannot find any other ways to bind my parameters than to rely on the odbc_execute function to to this.

NOTE: if I insert the SQL parameter values directly into the SQL statement it works fine, but I need to pass them separate from the query to avoid quoting problems.
