php Tron-Web库

PHP Tron-Web库是一个用于与Tron区块链进行交互的PHP库,它提供了一组简单易用的API,可以轻松地查询区块链数据、发送交易、调用智能合约等。下面是一些使用Tron-Web库的示例代码:
1. 连接到Tron节点
```php
require_once('path/to/tron-web/vendor/autoload.php');
use \Tron\Web;
$tronWeb = new Web('https://api.trongrid.io');
```
2. 获取账户信息
```php
$address = 'TJWZjQ4cX4wVfU1v3q2LXZL6yU6J6E3hXk';
$account = $tronWeb->getAccount($address);
echo 'Balance: ' . $account['balance'] . PHP_EOL;
echo 'Bandwidth: ' . $account['asset']['netUsed'] . PHP_EOL;
echo 'Energy: ' . $account['asset']['energyUsed'] . PHP_EOL;
```
3. 发送TRX交易
```php
$from = 'TJWZjQ4cX4wVfU1v3q2LXZL6yU6J6E3hXk';
$to = 'TWbYiJfDr1NpQrMwzgBQfG5m3F6cJ8Xn6D';
$amount = 100;
$result = $tronWeb->sendTransaction([
'to' => $to,
'from' => $from,
'amount' => $amount
]);
```
4. 调用智能合约函数
```php
$abi = '[{"constant":false,"inputs":[{"name":"_value","type":"uint256"}],"name":"setValue","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"getValue","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"}]';
$address = 'TB6sNiKbCGZ5pFpXvKXWV5P7n6uG6sLxL7';
$contract = $tronWeb->contract($abi, $address);
$contract->functions->setValue(123)->send();
$result = $contract->functions->getValue()->call();
```
在这些示例代码中,我们首先导入了Tron-Web库,并创建了一个TronWeb实例。然后,我们使用TronWeb实例来连接到Tron节点,获取账户信息,发送TRX交易和调用智能合约函数。需要注意的是,我们需要为每个智能合约定义其ABI,以便正确地编码和解码函数调用的参数和返回值。
