Blockchain API library (PHP, v1)
An official PHP library for interacting with the blockchain.info API.
Getting Started
Download the source or clone the repository. This php library works with the Composer package manager. Navigate to the root of the repository and run
$ composer install
This will create the /vendor folder in the repository root. In the php source, simply:
// Include the autoload.php from its vendor directory
require 'vendor/autoload.php'
// Create the base Blockchain class instance
$Blockchain = new \Blockchain\Blockchain();All functionality is provided through the Blockchain object.
###Call Limits
The official documentation lists API call limits, which may be bypassed with an API code. If you use a code, enter it when you create the Blockchain object:
$Blockchain = new \Blockchain\Blockchain($my_api_code);If you need an API code, you may request one here.
###Network Timeouts
Set the cURL timeout, in seconds, with the setTimeout member function:
$Blockchain->setTimeout($timeout_seconds);The default network timeout is 60 seconds.
A Note about Bitcoin Values
All Bitcoin values returned by the API are in string float format, in order to preserve full value precision. It is recommended that all arithmetic operations performed on Bitcoin values within PHP utilize the bcmath functions as follows:
#####bcadd Add Two Numbers
$result = bcadd("101.234115", "34.92834753", 8); // "136.16246253"#####bcsub Subtract Two Numbers
$result = bcsub("101.234115", "34.92834753", 8); // "66.30576747"#####bcmul Multiply Two Numbers
$result = bcmul("101.234115", "34.92834753", 8); // "3535.940350613"#####bcdiv Divide Two Numbers
$result = bcdiv("101.234115", "34.92834753", 8); // "2.89833679"The 8 in the final parameter of each bcmath function call represents the numerical precision to keep in the result.
More help on the bcmath functions can be found in the PHP BC Math documentation.
