介绍一个EOS Chain/Wallet RPC API的PHP开发包。
开始
你可以查看EOS的RPC API参考，但要注意缺少一些较新的方法。Wallet RPC API实现EOS v1.1.0 of RPC API reference。此外，这些文档中的一些示例也使用了过时的语法。
安装
composer require manamine/php-eos-rpc-sdk
配置
使用你最喜欢的RPC API主机和KEOSD在项目根目录中创建一个dotenv.env文件。你可以使用env.example作为模板：
cp .env.example .env
有一个漂亮的工厂方法来自动化实例所有依赖项：
$api = (new ChainFactory)->api();
$walapi = (new WalletFactory)->api();
$eos = (new EosRpc($api, $walapi));
示例
为了帮助你入门，运行一个简单的示例，它涵盖了所有API命令。
只需通过cli运行此命令即可查看所有命令的示例输出：
cd examples
php chain.php
php wallet.php
php eosrpc.php
API方法
涵盖了几乎所有区块链和钱包API方法。

echo $eos->pushAction("eosio", "buyram", ["payer"=>"tester","receiver"=>"tester","quant"=>"1.0000 EOS"], ["actor"=>"tester","permission"=>"active"]);
Transfer
交易支付
echo $eos->transfer("user", "tester", "1.0000 EOS", "memo");
Create Key Pair
创建密钥对并返回
$keyPair = $eos->createKeyPair("K1");

Tests
要运行测试套件，只需执行：
vendor/bin/phpunit
如果您想获得想象并检查代码覆盖率：
vendor/bin/phpunit --coverage-html tests/coverage
如果你真的很无聊，你可能想要运行一些静态分析：
vendor/bin/phpmetrics --report-html="tests/static" .
