Usage
RLP encode:
use Web3p\RLP\RLP; $rlp = new RLP; $encodedBuffer = $rlp->encode(['dog']); // to string, encoding: ascii utf8 hex $encodedBuffer->toString($encoding);
RLP decode:
use Web3p\RLP\RLP; $rlp = new RLP; $encodedBuffer = $rlp->encode(['dog']); // only accept 0x prefixed hex string $decodedArray = $rlp->decode('0x' . $encodedBuffer); // show dog echo $decodedArray[0]->toString('utf8');

decode
Returns array recursive length prefix decoding of given data.
decode(string $input)
String input - recursive length prefix encoded string.
Example
- Decode recursive length prefix encoded string.
use Web3p\RLP\RLP; $rlp = new RLP; $encodedBuffer = $rlp->encode(['web3p', 'ethereum', 'solidity']); $encodedString = $encodedBuffer; $decodedArray = $rlp->decode('0x' . $encodedString); // echo web3p echo $decodedArray[0]->toString('utf8'); // echo ethereum echo $decodedArray[1]->toString('utf8'); // echo solidity echo $decodedArray[2]->toString('utf8');
