FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

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.

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:

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:

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.

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

Or if put the following in your composer.json:

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):

(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!!
