You can take a look at a coin base transaction here:

The block reward is only 12.5, however the miner received more than 12.6, due to fees.
Topic: How does a miner receives a transaction fee (Read 204 times)
Each block has a coingen transaction for the block subsidy - so far so good.
But how does the miner gets the fees of transactions in a block?

Exactly the same way.
The "coingen transaction" of the block doesn't only have the block subsidy. It has the block subsidy + the transaction fees.
Is there a "getTransactionFees()" transaction?
Nope. Just the "coingen transaction"
Hi,
Transaction fees are implicit in Bitcoin tranasctions. They are the difference between the sum of the inputs' value and the sum of the outputs' value.
All transactions need to have `sum(outputs) <= sum(inputs)` (and not just equal! Which would, by the way not be relayed by most of the nodes).
A block generator needs to create a coinbase transaction outputs which value is <= to `block_subsidy + fees` with `fees = sum(inputs_of_all_txs) - sum(outputs_of_all_txs)` for other network (full) nodes to accept it.
Each block has a coingen transaction for the block subsidy - so far so good.
