php-electrum-api - Electrum library

Licence: GPL-3.0
Author: Pascal Krason <p.krason@padr.io>
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. 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 which will do everything else for you.

Install

First you need to install Composer, 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:

// 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.

$method = new \Electrum\Request\Method\Version();

try {
    $response = $method->execute();
} catch(\Exception $exception) {
    die($exception->getMessage());
}

$response->getVersion();

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.

$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.

$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()
    ));
}
