Code:

$a=ouvrirpage("https://mtgox.com/code/data/ticker.php");
$res=(json_decode($a, true));
$low = $res['ticker']['low'];

$a=ouvrirpage("http://bitcoincharts.com/t/weighted_prices.json");
$res=(json_decode($a, true));
$day = $res['USD']['24h'];

echo min($low, $day);

function ouvrirpage($site){
$ch = curl_init($site);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$res = curl_exec($ch);
curl_close($ch);
return $res;
}

or if you don't like curl:

Code:

$a=file_get_contents("https://mtgox.com/code/data/ticker.php");
$res=(json_decode($a, true));
$low = $res['ticker']['low'];

$a=file_get_contents("http://bitcoincharts.com/t/weighted_prices.json");
$res=(json_decode($a, true));
$day = $res['USD']['24h'];

echo min($low, $day);

Cool. Got it working with the curl one (never rechecked that one with the Last coding I did was GW-Basic in the early 90s.

And that was just copying and changing code, have never really coded anything from scratch.

Anyway, bounty on its way to your signature bitcoin address. Thanks!

file_get_contents might not work with https

http://mtgox.com/code/data/ticker.php is *really* long to respond, too

http://mtgox.com/code/data/ticker.php looks like it redirects to https to me.

Anyway I tried this and I'm getting a similar problem to Jeremy, so I'll try to see if I can fix it.

On my machine, specifying http://mtgox.com/code/data/ticker.php results in a 500 on the page, and this in the log:

Code:

[Mon Aug 08 19:39:18 2011] [error] [client 127.0.0.1] PHP Warning: file_get_contents(http://mtgox.com/code/data/ticker.php): failed to open stream: HTTP request failed! in /var/www/hi.php on line 2

Specifying https://mtgox.com/code/data/ticker.php results in the page hanging forever, and nothing at all in the logs. (not even an acknowledgement of the request, like Apache normally does).

Comment the line out that grabs the mt.gox data and the page loads fine.

Strangely, stream_get_wrappers() does show that https is available on my machine.

Yes, Mt.Gox is up here, just very slow.

I don't have the php curl wrapper installed, maybe I'll install it and try the other example.

Edit: Yep, the curl one works perfectly fine.

Well ok, you should test the code later: http://www.downforeveryoneorjustme.com/mtgox.com

Looks up to me.

Code:

$a=file_get_contents("http://mtgox.com/code/data/ticker.php");
$res=(json_decode($a, true));
$low = $res['ticker']['low'];

$a=file_get_contents("http://bitcoincharts.com/t/weighted_prices.json");
$res=(json_decode($a, true));
$day = $res['USD']['24h'];

echo min($low, $day);
?>

Hmmm.... Does that code return a value to you? Maybe it's a problem with my server, but on my link it just hangs. Does it return a value for anyone else who clicks on it? http://spendbitcoins.com/jefftest/last-24hr.php

I modified it just a tiny bit, tested it on my server and it works.

Code:

$a=file_get_contents("https://mtgox.com/code/data/ticker.php");
$res=json_decode($a, true);
$low = $res['ticker']['low'];

$a=file_get_contents("http://bitcoincharts.com/t/weighted_prices.json");
$res=json_decode($a, true);
$day = $res['USD']['24h'];

echo "\$low = ".$low."";
echo "\$day = ".$day."";
?>

For some reason wrapping json_decode() in parenthesis slowed it down a lot.

Nope, you should test with the curl function then

While dealing with php files, you always need to put the code between ''

Hmmm.... My code returns this:

While your code returns this:

http://spendbitcoins.com/jefftest/last-24hr.php

How do I get your code to just return a figure like mine does? Sorry for my ignorance. I'm not a programmer at all. Wink

Code:

$a=file_get_contents("https://mtgox.com/code/data/ticker.php");
$res=(json_decode($a, true));

$res=(json_decode($a, true));
$day = $res['USD']['24h'];

echo min($low, $day);

The following code gives my site it's current exchange rate.

Quote

$string = file_get_contents("http://bitcoincharts.com/t/weighted_prices.json");
$json_a=json_decode($string,true);
echo $json_a['USD']['24h'];
?>

2 BTC bounty for the first person who rewrites it to echo the lower of the last price on Mt Gox and the 24-hour weighted average on Mt Gox.

Thanks!
