Oracle OCI8 support for CI 4

HI again!
im having troubles with package/procedures executions when i got OUT variables in my package i dont know how to retrieve the returning OUT variable value.
Can someone gide me a bit? im foing this:

Code:

function addSection($parent_section, $sec_code, $sec_long){
        $params[0] = array('name' => ':P_PARENT_SEC', 'value' => $parent_section);
        $params[1] = array('name' => ':P_CODE', 'value' => $sec_code);
        $params[2] = array('name' => ':P_LONG', 'value' => $sec_long);
        $params[3] = array('name' => ':P_OPER', 'value' => 'add');
        $params[4] = array('name' => ':P_RESULT', 'value' => null, 'length' => 4000);
        $params[5] = array('name' => ':P_ERROR', 'value' => null, 'length' => 4000);
        $params[6] = array('name' => ':P_ERROR_ORA', 'value' => null, 'length' => 4000);

        $query = $this->db->storedProcedure('PAC_WIKI', 'WIKI_SECTION', $params);
        print_r($query);

        die();
        if ($this->db->transStatus() === false) {
            return $query;
        } else {
            return $query;
        }
    }

and that "print_r()" give me this array:

Code:

CodeIgniter\Database\OCI8\Result Object ( [connID] => Resource id #12 [resultID] => Resource id #13 [resultArray] => Array ( ) [resultObject] => Array ( ) [customResultObject] => Array ( ) [currentRow] => 0 [numRows:protected] => [rowData] => )

thks in advance!
