An official PHP library for interacting with the blockchain.info API.
Download the source or clone the repository. Copy the lib/ folder into your project and add:
require('lib/Blockchain.php');
$Blockchain = new 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:
$Blockchain = new Blockchain($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.
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 Add Two Numbers
$result = bcmul("101.234115", "34.92834753", 8); // "3535.940350613"#####bcdiv Add 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.
