I do not know any PHP but I'm trying to make a page to just echo a result which I can then use as a conky config.

This is what I have tried

<?php  
$content=file_get_contents("https://btc-e.com/api/2/ltc_usd/ticker");
$data=json_decode($content);

echo "Current Price: $";
echo $data->ticker->avg;;
?>

But I just get "Current Price: $" without the actual price.

Any help is appreciated, thanks!

  • Thanks however I got Current Price: $NULL when adding this, I put it at the end not sure if thats where it should of been. Thanks Commented Sep 9, 2014 at 21:53
  • So it means, there is no json encoded output in this URL. Commented Sep 9, 2014 at 21:55
  • That means $data is NULL. You likely do not have valid JSON Commented Sep 9, 2014 at 22:09

First of all, I am assuming you're new to PHP. Welcome. In the future, you should perform the following steps before you even start asking for help.

  1. Enable PHP error messages
  2. Look at the error messages if any
  3. Dump the variable(s) that aren't behaving as expected
  4. You'll probably have your answer by now
  5. If not, then ask for help

In your case it's most likely because you have the PHP setting allow_url_fopen set to Off. Set it to On in your php.ini config file.

If you're using shared hosting, you're out of luck. You'll need to fetch the content using cURL instead stackoverflow.com/questions/21642604/…
