How can decode tx info

i want to got transfer in asset(atom), by this step:

curl ‘localhost:26657/block?height=1000’, i have got the tx:
“data”: {
“txs”: [
“5wHwYl3uCkaoo2GaChQmSIu8hxpJxLcCuIi8fiHN4TMwrRIU/Af1cEG7Rcs/6LjTl7YjRSymJfYaFAoFdWF0b20SCzE0OTk5OTk1MDAwEhMKDQoFdWF0b20SBDUwMDAQwJoMGmoKJuta6YchAwswBShaB1wkZBctLIhYqBC3JrAI28XGzxP+rVEticGEEkAc+khTkKL9CDE47aDvjEHvUNt+izJfT4KVF2v2JkC+bmlH9K08q3PqHeMI9Z5up+XMusnTqlP985KF+SI5J3ZOIhhNYWRlIGJ5IENpcmNsZSB3aXRoIGxvdmU=”,

]
},

this block have 2 tx, how decode this tx?

Let me help you, in PHP you can use:

function decodetx($hashing) {
  return hash('sha256', base64_decode($hashing));
}

$tx = "5wHwYl3uCkaoo2GaChQmSIu8hxpJxLcCuIi8fiHN4TMwrRIU/Af1cEG7Rcs/6LjTl7YjRSymJfYaFAoFdWF0b20SCzE0OTk5OTk1MDAwEhMKDQoFdWF0b20SBDUwMDAQwJoMGmoKJuta6YchAwswBShaB1wkZBctLIhYqBC3JrAI28XGzxP+rVEticGEEkAc+khTkKL9CDE47aDvjEHvUNt+izJfT4KVF2v2JkC+bmlH9K08q3PqHeMI9Z5up+XMusnTqlP985KF+SI5J3ZOIhhNYWRlIGJ5IENpcmNsZSB3aXRoIGxvdmU=";

$value = decodetx($tx);
echo $value;

Also if you have the decodetx() function already included:

$json = json_decode($json, true);

  // GET ALL TRANSACTIONS FROM THAT BLOCK
  $num_txs = $json["block"]["header"]["num_txs"];

  // IF WE HAVE ANY TRANSACTIONS, CHECK THEM
  if ($num_txs > 0)
  {
  	// GET ALL TRANSACTIONS
  	$txs = $json["block"]["data"]["txs"];

  	// LOOP ALL TRANSACTIONS
  	foreach ($txs as $transaction => $value) {
  		$value = decodetx($value);
        // DO SOMETHING WITH THAT VALUE
     }

}
