encode()

static M8B\EtherBinder\Contract\ABIEncoder::encode ( string $signature, array $data, bool $withTransactionSignature = true )

static

Encodes ABI data for an Ethereum smart contract function. It returns binary blob which can be bin2hex()-ed for presentation purposes.

Parameters

string	$signature	The function signature including the function name and its parameters.
array	$data	The data to encode.
bool	$withTransactionSignature	Whether to prepend the function selector hash to the encoded data.

Returns

string The ABI-encoded binary blob.

Exceptions

EthBinderLogicException	Thrown if function name end is not found or indicates other bug.
EthBinderArgumentException	Thrown if validation of signature fails.

explodeTuple()

static M8B\EtherBinder\Contract\ABIEncoder::explodeTuple ( string $types )

static

Splits a tuple type into its constituent types, preserving child tuples as single type. Input must start with ( and end with ), without function name etc. Example input and output: "(uint256,(uint8,uint16)[],bytes)" => ["uint256", "(uint8,uint16)[]", "bytes"]

Parameters

string

$types

The tuple types string.

Returns

array An array of the constituent types.

Exceptions

EthBinderArgumentException

Thrown if provided tuple is invalid.
