先解锁账户

$opts = [
            'jsonrpc' => '2.0',
            'method' => 'personal_unlockAccount',	//解锁账户接口
            'params' => [

				'123456'	//账户密码
			],
            'id' => time()
        ];

解锁账户常见错误

1. 节点里面有没有导入需要解锁的地址, 解锁失败
2. 地址的密码错误,解锁失败

查询账户余额

$opts = [
            'jsonrpc' => '2.0',
            'method' => 'eth_call', //查询以太坊代币的jsonrpc接口
            'params' => [

		            //0x70a08231000000000000000000000000 为固定用法, 后面加上去掉0x的from
		        ],
		        1=>'latest'	//”latest”, “earliest” or “pending”
				
			],
            'id' => time()
        ];

查询账户常见错误

1. 地址有误
2. data数据组装有问题

查询结果

array(2) {
  ["status"] => bool(true)
  ["data"] => array(3) {
    ["jsonrpc"] => string(3) "2.0"

  }
}

余额为: 把 result字段的0x去掉, 转成十进制 ,在除 1000000  (小数尾数为6位)
$account = hexdec( substr( ['data']['result'], 2 ) ) / 1000000;
