I have this issue with this little bitcoin ticker code I'm trying to put on my site bitcoinvalues.net, I used to work pulling the data from Mt.Gox but not anymore cause they shutdown their site. What I want to do now is replacing Mt.Gox with either bitstamp.net/api/ticker/ and blockchain.info/ticker ticker. The codes are below. Can you guys help me with this?

<?php
         //first fetch the current rate from MtGox
         $ch = curl_init('https://mtgox.com/api/0/data/ticker.php');
                 curl_setopt($ch, CURLOPT_REFERER, 'Mozilla/5.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
                 curl_setopt($ch, CURLOPT_USERAGENT, "CakeScript/0.1");
                 curl_setopt($ch, CURLOPT_HEADER, 0);
                 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
                 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                 $mtgoxjson = curl_exec($ch);
                 curl_close($ch);

         //decode from an object to array
                 $output_mtgox = json_decode($mtgoxjson);
                 $output_mtgox_1 = get_object_vars($output_mtgox);
                 $mtgox_array = get_object_vars($output_mtgox_1['ticker']);

 ?>
 <br/>
 <br/>
 Last:&nbsp;<?php echo $mtgox_array['last'];   ?><br/>
 High:&nbsp;<?php echo $mtgox_array['high'];   ?><br/>
 Low:&nbsp;&nbsp;<?php echo $mtgox_array['low'];   ?><br/>
 Avg:&nbsp;&nbsp;&nbsp;<?php echo $mtgox_array['avg'];   ?><br/>
 Vol:&nbsp;&nbsp;&nbsp;<?php echo $mtgox_array['vol'];   ?><br/>

Here's the data extraction - up to you how you display it:

header('Content-Type: text/html; charset=utf-8');
function extractData($url, $clientName)
{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_REFERER, 'Mozilla/5.0 (compatible; ' . $clientName. '  PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
    curl_setopt($ch, CURLOPT_USERAGENT, "CakeScript/0.1");
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $json = curl_exec($ch);
    curl_close($ch);
    $array = json_decode($json,true);
    return $array;               
}

$url = 'http://www.bitstamp.net/api/ticker/';
$clientName = 'Bitstamp';

$bitstamp = extractData($url,$clientName);

$url = 'http://blockchain.info/ticker';
$clientName =  'Blockchain';

$blockchain = extractData($url,$clientName);
echo "<pre>";
print_r($bitstamp);

print_r($blockchain);
echo "</pre>";

The blockchain gives an array of arrays - a number of different currencies.

Works like a charm. Thank you so much. There is one little issue though. I pulled Bitstamp using

<?php echo $bitstamp['last'];   ?>

but the same is not working for Blockchain. I tried $blockchain and $blockchain_array but neither working. And for Blockchain, how can I add an api key that will allow me to make unlimited request? They have issued me an api key so I can do do. You can see it on the site: http://www.bitcoinvalues.net

blockchain returns a different json as I mentioned in my post:

  "TWD" : {"15m" : 15787.31, "last" : 15787.31, "buy" : 15771.92, "sell" : 15786.4,  "symbol" : "NT$"}

So decide upon a currency to compare with - let's assume USD:

$blockchain = extractData($url,$clientName)['USD'];

Now...

echo $blockchain['last']; //should give 523.29

As for your KEY, I'd have to look at the documentation, but it should all be there. From what I remember though, is the ticker part of the api? I thought it was separate. The Key (AFAIK) will allow you to buy/sell and change account settings.

I tried $blockchain = extractData($url,$clientName)['USD'];

What version of PHP are you using? Perhaps it's too old.

Anyway, use this in that case...

$blockChainArray = extractData($url,$clientName);
$blockchain = $blockChainArray['USD'];

and it broke the site. http://www.bitcoinvalues.net shows a blank page.

Tell me you're not updating the live site without testing it locally or on a testing server!

Sorry I'm not signing up to anything. A quick look at the API, suggests what I originally thought. The ticker is not part of the api - or if it is, it's not documented (AFAIK).

Without delving into the documentation myself, I couldn't really say. Read the API documentation - and if the answer's not there - contact them.
