# php-electrum-api - Electrum library
```
Licence: GPL-3.0
Author: Pascal Krason
Language: PHP 5.6-7.1
```
Please note, this library is by far not completed and but can be used in production. Until now i only implemented the most commonly used API-Calls. If you think im missing something, just create an issue or fork the project.
# Setting up Electrum
First you need to setup a new Electrum wallet. Follow the instructions according to your OS at the [Electrum Download Page](https://electrum.org/#download). After the successfull installation you need to set a rpcport by typing:
```
electrum setconfig rpcport 7777
electrum setconfig rpcuser "username"
electrum setconfig rpcpassword "password"
```
Then we can create a default wallet, dont forget to note your generated seed, it's nescessary if you want to recover it one day:
```
electrum create
```
Now we can go ahead and start Electrum in daemon mode:
```
electrum daemon start
```
Since some new version electrum wants you to load your wallet by hand on startup:
```
electrum daemon load_wallet
```
# Requirements
On the PHP side there are not much requirements, you only need at least PHP 5.6 and the curl-Extension installed. Then you can go ahead ans it through [Composer](http://getcomposer.org) which will do everything else for you.
# Install
First you need to install [Composer](https://getcomposer.org/doc/00-intro.md), after you accomplished this you can go ahead:
```
composer require padrio/php-electrum-api
```
Then you can simply include the autoloader and begin using the library:
```php
// Include composer autoloader
require_once 'vendor/autoloader.php';
```
# Examples
## Basic example
A very basic useage example. Every API-Call has it's own request-object. You simply create one and execute it.
```php
$method = new \Electrum\Request\Method\Version();
try {
$response = $method->execute();
} catch(\Exception $exception) {
die($exception->getMessage());
}
$response->getVersion();
```
## Create new wallet
Create default wallet:
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$wallet = new \Electrum\Request\Method\Wallet\CreateWallet($client);
$response = $wallet->execute();
```
This code is similar to the command:
```bash
$ electrum create
```
You can also create more wallets with custom names specifying flag of the new wallet.
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$wallet = new \Electrum\Request\Method\Wallet\CreateWallet($client);
$response = $wallet->execute(['wallet_path' => '~/.electrum/wallets/your_wallet']);
```
This code is similar to the command:
```bash
$ electrum create -w ~/.electrum/wallets/your_wallet
```
Response will be:
```php
[
'seed' => 'wallet seed',
'path' => 'path where wallet file is stored',
'msg' => 'Please keep your seed in a safe place; if you lose it, you will not be able to restore your wallet.',
];
```
## Load wallet
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$load_wallet = new \Electrum\Request\Method\Wallet\LoadWallet($client);
$load_wallet->execute(['wallet_path' => '~/.electrum/wallets/your_wallet']);
````
## List wallets
Get list of all loaded wallets:
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$list_wallets = new \Electrum\Request\Method\Wallet\ListWallets($client);
$list_wallets->execute();
```
## Get new address
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$wallet = new \Electrum\Request\Method\Payment\AddRequest($client);
$tx = $wallet->execute();
echo $tx->getAddress();
```
## Create new address for wallet
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$newAddress = new \Electrum\Request\Method\Address\CreateNewAddress($client);
$newAddress->execute(['wallet' => '~/.electrum/wallets/your_wallet']);
```
## Make a new Payment
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
$method = new \Electrum\Request\Method\Payment\PayTo($client);
$method->setDestination('BTC4ddress1234'); //Destination parameter is the address where we'll send the btc
$method->setAmount(1); //send 1 BTC = 10k usd
$tx = $method->execute(); //$tx returns the transaction ID of the payment, this is still not sent to the blockchain
/**
* @param array ['password' => '']
* If the Electrum wallet is encrypted with a password use the following execute method instead
* The previous one will return an error of "Password required"
*/
//$tx = $method->execute(['password' => 'myPass123']); //
$broadcast = new Electrum\Request\Method\Payment\Broadcast($client);
$broadcast->setTransaction($tx);
$result = $broadcast->execute(); //broadcasts payment to the blockchain
echo $result;
A payment has been made
```
## Custom Client Configuration
Every Request/Method takes a `Electrum\Client`-instance as parameter which replaces the default one. A custom instance can be usefull if you want to set custom config params like another Hostname or Port.
```php
$client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'username', 'password');
$method = new \Electrum\Request\Method\Version($client);
try {
$response = $method->execute();
} catch (\Exception $exception) {
die($exception->getMessage());
}
$response->getVersion();
```
## Advanced exception handling
Dealing with exceptions is easy. You can catch two types of exceptions which indicates whether it's an Request or Response fault.
```php
$method = new \Electrum\Request\Method\Version();
try {
$response = $method->execute();
} catch (\Electrum\Request\Exception\BadRequestException $exception) {
die(sprintf(
'Failed to send request: %s',
$exception->getMessage()
));
} catch(\Electrum\Response\Exception\BadResponseException $exception) {
die(sprintf(
'Electrum-Client failed to respond correctly: %s',
$exception->getMessage()
));
}
```
