How can I access the TXN\_ID in the following object with PHP? Below is a print\_r of the object:

```
$txn_object = $txn_params[last_payment];
error_log( print_r($txn_object,true) );

```

I get this in the error log:

```
EE_Payment Object
(
    [_props_n_values_provided_in_constructor:protected] => Array(
        [PAY_ID] => 4168
        [TXN_ID] => 746919
        [STS_ID] => PAP
        [PAY_timestamp] => 2017-08-29 14:06:26
        [PAY_source] => CART
        [PAY_amount] => 24.000
        [PMD_ID] => 11
        [PAY_gateway_response] => submitted_for_settlement
        [PAY_txn_id_chq_nmbr] => 96g71gxv
        [PAY_po_number] => 
        [PAY_extra_accntng] => 
        [PAY_details] => 
    )
)

```

I've tried a few things, but can't seem to get that value but comes back blank:

```
$txn_object->_props_n_values_provided_in_constructor[0]->TXN_ID

```
