从控制器和视图之间的公共API URL显示json数据的正确方法

Question

What is the appropriate way to display json data (the whole json string) from a public API URL in CodeIgniter between a controller and view? (The json data changes over time.)

For example the following URL:

https://btc-e.com/api/2/btc_usd/ticker

returns:

{"ticker":{"high":1055.91895,"low":730.10101,"avg":893.00998,"vol":34644526.18952,"vol_cur":38351.83433,"last":800,"buy":802.712,"sell":802.711,"updated":1385926730,"server_time":1385926731}}

How can I display this with CodeIgniter on my site?

Answer 1

$json = file_get_contents('https://btc-e.com/api/2/btc_usd/ticker');
$obj = json_decode($json); //returns as an object
echo $obj->ticker->high;  // you can access like this all the values
