PHP SDK suggestion

[ricattricks]

You should throw exceptions so we can handle errors and prevent fatal errors from breaking the flow when retrieving possible transactions. For exemple in this statement:

TransactionCaller::getTransactionDetailsByTransactionIdRequest($transaction_id, $credentials, $config_arr);

If "$transaction_id" is invalid, then it will likely return a FATAL ERROR and brreak the code, unless there's already an existing workaround from the SDK to handle this.
