PHP Algorand SDK

beaconet · May 6, 2021, 3:24pm

Hi Felipe ,

It’s Work !!

Now I understand where I was wrong. I entered the wallet name instead of the ID
Just one more question:

my genesis hash, read from the goal node status command, returns a different value than yours. If I use my value the procedure doesn’t work.

My genesis hash is : wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=

Thank you

Marco

Hi Marco,

This is a good question, YBQ4JWH4DW655UWXMBF6IVUOH5WQIGMHVQ333ZFWEC22WOJERLPQ= is wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8= base64 decoded and base32 encoded.

ex: b32::encode(base64_decode(“wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=”));

To have no confusion, I updated the SDK, now you can use Genesis Hash on base 64, according:

And Node status command / method.

You can use the new update at Github.

Hi Felipe ,
thanks for update.

To read the last round i use this :

$return=$algorand->get("v2","transactions","params");

and assign to a variable :

$return_array=json_decode($return['response']);
$lastround=$return_array->last-round ;

but I receive some errors …

I want pass last-round data for transaction array

$transaction=array(
        "txn" => array(
                "type" => "pay", //Tx Type
                "fee" => 1000, //Fee
                "fv" => $lastround, //Take the last round
                "gen" => "mainnet-v1.0", // GenesisID
                "gh" => "YBQ4JWH4DW655UWXMBF6IVUOH5WQIGMHVQ333ZFWEC22WOJERLPQ=", //Genesis Hash
                "lv" => $lastround+200, //Add 200 round 
                "note" => $content, //You note
                "snd" => "", //Sender
                "rcv" => "", //Receiver
                "amt" => 1000, //Amount
            ),
);

Because of dash “-” the correct PHP syntax is:: $return_array->{‘last-round’};

Example of use:

require_once 'sdk/algorand.php';
$algorand = new Algorand_algod('{algod-token}',"localhost",53898); //get the token key in data/algod.token and port in data/algod.net

#Get parameters for constructing a new transaction
$return=$algorand->get("v2","transactions","params");
$return_array=json_decode($return['response']);

$lastround=$return_array->{'last-round'};
print_r($return_array);

/* Response:
stdClass Object
(
    [consensus-version] => https://github.com/algorandfoundation/specs/tree/ac2255d586c4474d4ebcf3809acccb59b7ef34ff
    [fee] => 0
    [genesis-hash] => wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=
    [genesis-id] => mainnet-v1.0
    [last-round] => 13652572
    [min-fee] => 1000
)

Hi Felipe,
this is Marco, I am struggling to init a wallet.

I instantiate correctly kmd and print version info, but both calls to wallet init and wallet list return the same message:

[code] => 404 [message] => {“message”:“Not Found”}

My code is the following:

$algorand_kmd = new Algorand_kmd(‘b1bdecba8a5374ea4e4b853df49f9d58c1877ee5edcbd2fba63653228dc35d74’,“localhost”,53898);

    $return=$algorand_kmd->get("versions");
    print_r($return);
    $return=$algorand_kmd->get("v1","wallets");
    print_r($return);
    //wallet init
    $params['params']=array(
        "wallet_id" => "27008546fcceca5252bf3938f21eff5e",
        "wallet_password" => "shype2022",
    );
    $return=$algorand_kmd->post("v1","wallet","init",$params);
    $return_array=json_decode($return['response']);
    print_r($return);

I found out it was just the wrong port!

felipe · January 31, 2022, 6:52pm

Hi Marco,
Good!
Any questions let me know.

beaconet · February 1, 2022, 4:53pm

Hi Felipe,

I need to show primary key during address creation. I use export function but receive encoded string.

How can I do this ?

Thank you
Marco

felipe · February 1, 2022, 7:15pm

Hi Marco,

If you referring about the private key, it is already returned encoded in base 64, already in the same format needed to do the import as KMD REST APIs require.

In case you need the mnemonic words, I’m creating a version of algokey (algokey - Algorand Developer Portal) in php too, I intend to release it soon.

It’s possible to export the mnemonics using the command line ./goal account export -a {KEY}

Regards

beaconet · February 1, 2022, 7:35pm

Hi Felipe,

I need mnemonic , so for moment using goal command.

Thank you

Marco

Hi Felipe, I am trying to make an atomic transfer, with two basic transactions.
but when I try to broadcast the transactions I get this error:

[code] => 400
[message] => {"message":"TransactionPool.Remember: transactionGroup: incomplete group: 2CR4DHPI6ACSKI6T7P3VWEX5ZLEJUGXKOP2KKF2OUYN5YGLPVQLA != 2TW3AQRJYQDPBAVXGGDIQMX27FD4YCDOBANADXQAQJRSIUVBEVPQ ({{} [4LZE3BP4P66DPONNX2AENAU7JFTBWWOJ4OH7WBVX236JCF3JGQHA P6RZAYJSYKDLXWMOZZ6NAVJFNYY3FCWMGZSRQT4VMHXLGHEQ2XCQ]})"}

My code is the following:

//Transaction 1
$transactions=array();
$transactions=array(
“txn” => array(
“type” => “pay”, //Tx Type
“fee” => 1000, //Fee
“fv” => $lastRound, //First Valid

),
);
//Transaction 2
$transactions=array(
“txn” => array(

),
);

//2) Group TRansactions
$groupid=$algorand_kmd->groupid($transactions);
#Assigns Group ID
$transactions[0]['txn']['grp']=$groupid;
$transactions[1]['txn']['grp']=$groupid;

// echo "Transactions\n";
// print_r($transactions);

//3) Sign Transactions
#Sign Transaction 1
$txn="";
$params['params']=array(
//"public_key" => $algorand_kmd->pk_encode($mainAccountAddress),
"transaction" => $algorand_kmd->txn_encode($transactions[0]),
"wallet_handle_token" => $wallet_handle_token,
"wallet_password" => $mainWalletPw,
);


$return=$algorand_kmd->post("v1","transaction","sign",$params);
$r=json_decode($return['response']);
$txn.=base64_decode($r->signed_transaction);

echo "sign t1\n";
print_r($return);

#Sign Transaction 2
$params['params']=array(

$return=$algorand_kmd->post("v1","transaction","sign",$params);

$params['transaction']=$txn;
$return=$algorand->post("v2","transactions",$params);

print_r($return);

I can’t figure out the reason of this error

felipe · February 8, 2022, 2:42pm

Hi Marco,

Can you print the $params[‘transaction’] or $txn before the broadcast is sent to review?

AlgoShype · February 8, 2022, 3:16pm

Sure, This is the $txn value:

Thanks Marco, please print as base64 using echo base64_encode($txn);.

Hi Felipe:

echo (base64_encode($txn)):

Hi Marco, I identified the problem, in some cases with note, when computing the group id, the hash did not return what was expected, I’m applying the necessary filters and encoders, I’m just doing all the necessary tests.

beaconet · February 15, 2022, 9:36am

Hi Felipe,

I try to remove the note field, but have same result.

Hi Felipe,

this is our version of php : PHP Version 7.2.34-28+ubuntu18.04.1+deb.sury.org+1
