Thank you for the fast reply I really appreciate, however I've done many tests on various txs and my script worked like a charm.

Ok thanks, I've missed that

Code:
require_once("src/class.connector.php");
$rpc = new Connector("username", "password", "127.0.0.1", "18333");

$txinfo = $rpc->getrawtransaction($txid, 1); // get info from received tx
$txinput = $txinfo["vin"][0]["txid"]; // result: fd018b006c8702139d1c230460c1a71f99d364d59c339e26cc8588cf622a5be9

I'm actually doing it via Bitcoin API and PHP. I tried gettransaction but it doesn't print the fee amount.
gettransaction will not give you the fee if you received the transaction, only if you sent. You should use getrawtransaction. With that command you can retrieve the vout values of all of the outpoints of the inputs and the output. Then just use those the calculate the fee.For:
7f502f28ca8d162300a1bbc8cb7dfa6f38533596ac97c29e1d1de9ca614ae350
Total Inputs 11.69569708 tBTC
Total Outputs -11.69563674 tBTC
= 0.00006034 tBTC fees (subtracting total outputs from total inputs)
For the second, total inputs and total outputs are the same: 506.68468049 tBTC
So there are 0.0 fees.
Does that make sense?
If you aren't asking how to calculate the fees for that transaction as it was confirmed, I am not sure what you are asking.

I'm actually doing it via Bitcoin API and PHP. I tried gettransaction but it doesn't print the fee amount.
You might try using getrawtransaction and then subtracting the outputs from the inputs.

I'm coding a specific PHP script that requires to retrieve the fee from a received transaction.
Let's focus on the following transactions that I received on my own testnet address:
Transaction with fees: 7f502f28ca8d162300a1bbc8cb7dfa6f38533596ac97c29e1d1de9ca614ae350
Transaction with no fees: 9afe2bf122e4ec26cff427015ea680f4e03877077376d1d9b1c6d6f63563acc7
I couldn't figure out how to get the fee out of the transactions, so can you suggest me all possible methods? Thank you!
I'm actually storing all send-receive transactions on my database through blocknotify + walletnotify + gettransaction.
PS: do not confuse my help request with calculating the fee of transactions prematurely before sending.
