I have an Oracle stored proc that takes 2 parameters. `userid` as an input parameter and an Oracle table with 2 columns as second out parameter. How can I invoke the procedure from PHP? I think that the problem stands in the `oci_bind_*` for the second parameter. I've tried `oci_bind_array_by_name` but I always get `PLS-00306: wrong number or types of arguments in call to GET_VALUES`.  

Can anyone help me, please?

Here is my code:

```
$tab=array();
$query = "begin GET_VALUES(:P_CUSTOMERCODE,:P_TAB); end;";
$stmt = oci_parse($ora_conn, $query) or die(oci_error());
oci_bind_by_name($stmt,":P_CUSTOMERCODE",$codUtente,255);
oci_bind_array_by_name($stmt,":P_TAB",$tab,100,100,SQLT_CHR);
oci_execute($stmt) or die(oci_error());

```
