区块链账本

安装

composer require invoice/block-chain-data

用法

use InvoiceBlockChainData; //创建账本 $BlockChain = new BlockChainData('BlockChain.dat'); //新增块 for ($i = 0; $i < 10; $i++) { $BlockChain->addBlock('test'.$i); } //返回账本Hash print_r($hash=$BlockChain->getHash()); //返回块数量 var_dump($BlockChain->count()); //校对账本是否被修改 var_dump($BlockChain->verifyHash($hash)); /** * 分页查询账本 * @param int $limit 条数 * @param int $offset 偏移 * @throws Exception 区块链被破坏 * @return null|array */ print_r($BlockChain->find($limit = 1, $offset = 0)); /** * 返回所有账本数据 * @throws Exception 区块链被破坏 * @return null|array */ print_r($BlockChain->findAll());
