```

### Using provider

[](#using-provider)

```
use Web3\Web3;
use Web3\Providers\HttpProvider;
use Web3\RequestManagers\HttpRequestManager;

$web3 = new Web3(new HttpProvider(new HttpRequestManager('http://localhost:8545')));

// timeout
$web3 = new Web3(new HttpProvider(new HttpRequestManager('http://localhost:8545', 0.1)));
```

### You can use callback to each rpc call:

[](#you-can-use-callback-to-each-rpc-call)

```
$web3->clientVersion(function ($err, $version) {
    if ($err !== null) {
        // do something
        return;
    }
    if (isset($version)) {
        echo 'Client version: ' . $version;
    }
});
```

### Eth

[](#eth)

```
use Web3\Web3;

$web3 = new Web3('http://localhost:8545');
$eth = $web3->eth;
```

Or

```
use Web3\Eth;

$eth = new Eth('http://localhost:8545');
```

### Net

[](#net)

```
use Web3\Web3;

$web3 = new Web3('http://localhost:8545');
$net = $web3->net;
```

Or

```
use Web3\Net;

$net = new Net('http://localhost:8545');
```

### Batch

[](#batch)

web3

```
$web3->batch(true);
$web3->clientVersion();
$web3->hash('0x1234');
$web3->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        // it may throw exception or array of exception depends on error type
        // connection error: throw exception
        // json rpc error: array of exception
        return;
    }
    // do something
});
```

eth

```
$eth->batch(true);
$eth->protocolVersion();
$eth->syncing();

$eth->provider->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});
```

net

```
$net->batch(true);
$net->version();
$net->listening();

$net->provider->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});
```

personal

```
$personal->batch(true);
$personal->listAccounts();
$personal->newAccount('123456');

$personal->provider->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});
```

### Contract

[](#contract)

```
use Web3\Contract;

$contract = new Contract('http://localhost:8545', $abi);

// deploy contract
$contract->bytecode($bytecode)->new($params, $callback);

// call contract function
$contract->at($contractAddress)->call($functionName, $params, $callback);

// change function state
$contract->at($contractAddress)->send($functionName, $params, $callback);

// estimate deploy contract gas
$contract->bytecode($bytecode)->estimateGas($params, $callback);

// estimate function gas
$contract->at($contractAddress)->estimateGas($functionName, $params, $callback);

// get constructor data
$constructorData = $contract->bytecode($bytecode)->getData($params);

// get function data
$functionData = $contract->at($contractAddress)->getData($functionName, $params);
```

Assign value to outside scope(from callback scope to outside scope)
===================================================================

[](#assign-value-to-outside-scopefrom-callback-scope-to-outside-scope)

Due to callback is not like javascript callback, if we need to assign value to outside scope, we need to assign reference to callback.

```
$newAccount = '';

$web3->personal->newAccount('123456', function ($err, $account) use (&$newAccount) {
    if ($err !== null) {
        echo 'Error: ' . $err->getMessage();
        return;
    }
    $newAccount = $account;
    echo 'New account: ' . $account . PHP_EOL;
});
```

Examples
========

[](#examples)

To run examples, you need to run ethereum blockchain local (testrpc).

If you are using docker as development machain, you can try [ethdock](https://github.com/sc0vu/ethdock) to run local ethereum blockchain, just simply run `docker-compose up -d testrpc` and expose the `8545` port.
