i make a little proxy for get ticker data

proxy2.php

Code:

<?php
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_USERAGENT, "curl/7.21.3 (x86_64-pc-linux-gnu) libcurl/7.21.3 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.18");
  curl_setopt($ch, CURLOPT_URL, 'https://mtgox.com/code/data/ticker.php');
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  $output = curl_exec($ch);
  curl_close($ch);
  echo json_encode($output);
  ?>

in html file i have

Code:

<script type="text/javascript">
		$.getJSON("proxy2.php", function(data) {
			console.log(data);
			//$('#ticker_mtgox').html(parseFloat(data.ticker.last).toFixed(2) + ' USD');
		});
</script>
<li class="current">MtGox: </li>
<li id="ticker_mtgox"></li>

in log i have

Code:

"{\"ticker\":{\"high\":12.17887,\"low\":11.4919,\"avg\":11.931998599,\"vwap\":11.880445695,\"vol\":61162,\"last_all\":12.1,\"last_local\":12.1,\"last\":12.1,\"buy\":12.09999,\"sell\":12.1}}"

 D:
in ticker_mtgox y have nothing

maybe the problem is because I should get something like this

Code:

{"ticker":{"high":12.17887000,"low":11.49190000,"vol":61092.00000000,"last":12.10000000,"buy":12.09999000,"sell":12.10000000,"date":1344913200}}

without the "\" symbols

can help me to fix it..or tell me a way to "ticker_mtgox" work?

the output from curl_exec is already in json, you are double encoding with json_encode, hence the \"

I didn't even see that, but I think he mean json_decode to get the json into an array
