IMPORTANT v1.3.0 adds the option to choose a fee strategy and by default chooses DYNAMIC, please check docs/CHANGELOG.md for the details!!

IMPORTANT! FLOATS ARE EVIL!!

As is best practice with financial data, The API returns all values as an integer, the Bitcoin value in Satoshi's. In PHP even more than in other languages it's really easy to make mistakes whem converting from float to integer etc!

When doing so it's really important that you use the bcmath or gmp libraries to avoid weird rounding errors! The BlockTrail SDK has some easy to use functions to do this for you, we recommend using these and we also strongly recommend doing all Bitcoin calculation and storing of data in integers and only convert to/from Bitcoin float values for displaying it to the user.

use Blocktrail\SDK\BlocktrailSDK;

echo "123456789 Satoshi to BTC: " . BlocktrailSDK::toBTC(123456789) . " \n";
echo "1.23456789 BTC to Satoshi: " . BlocktrailSDK::toSatoshi(1.23456789) . " \n";

A bit more about this can be found in our documentation.

Requirements

The SDK requires PHP 5.6+ and the Intl, GMP and BCMath PHP extensions.
To install these on Ubuntu use:

sudo apt-get install php5-bcmath php5-intl php5-gmp
sudo php5enmod mcrypt

BCMath should already be part of the default php5 package

On Windows you need to uncomment the extensions in your php.ini if they are not already enabled:

extension=php_intl.dll  
extension=php_gmp.dll

Installation

To install the SDK, you will need to be using Composer in your project. If you aren't using Composer yet, it's really simple! Here's how to install composer and the BlockTrail PHP SDK.

# Install Composer
curl -sS https://getcomposer.org/installer | php

# Add the BlockTrail SDK as a dependency
php composer.phar require blocktrail/blocktrail-sdk

Next, require Composer's autoloader, in your application, to automatically load the BlockTrail SDK in your project:

require 'vendor/autoload.php';
use Blocktrail\SDK\BlocktrailSDK;

Or if put the following in your composer.json:

"blocktrail/blocktrail-sdk": "1.2.*"

Windows Developers
A note for windows developers: you may encounter an issue in php with cURL and SSL certificates, where cURL is unable to verify a server's cert with a CA ((error 60)[http://curl.haxx.se/libcurl/c/libcurl-errors.html]).
Too often the suggested solution is to disable ssl cert verification in cURL, but this completely defeats the point of using SSL. Instead you should take two very simple steps to solve the issue permanently:

  1. download cacert.pem from the curl website. This is a bundle of trusted CA root certs extracted from mozilla.org. Save it in a folder within your php installation.
  2. open your php.ini and add/edit the following line (use an absolute path to where you placed the cert bundle):
curl.cainfo = C:\php\certs\cacert.pem

(Optional) Use libsecp256k1

The underlying bitcoin-php library that is used to sign transactions can use libsecp256k1 for (A LOT) faster signing of transactions. If the secp256k1-php PHP extension is installed it will be automatically used and will greatly improve performance!

The installation is a bit cumbersome though and because libsecp256k1 still changes a lot building might not always work! If you can get it to install; AWESOME, if not, have patience while we're working on figuring out how to provide installers for them.

MAKE SURE TO RUN THE TESTSUITE OF secp256k1-php AFTER THE INSTALL BEFORE ENABLING THE EXTENSION!!
