How to get current value of bitcoin

Question

I want to get the current bitcoin price when I call a function. I found https://mtgox.com/api/0/data/ticker.php but it returns

{"ticker":{"high":12.43,"low":11.7,"avg":12.10615987,"vwap":12.098317306,"vol":58453,"last_all":12.34351,"last_local":12.34351,"last":12.34351,"buy":12.3341,"sell":12.34351}}

How can I set a PHP variable to just the value of last_all (12.34351)

Answer 1

You can use json_decode to transform it into a PHP object.

$content = json_decode($string, true);

echo $content["last_all"];
