Bit Coin API for bit coin rate - php

I am using following code to get bitcoin price it is working off line but not working on server.
$api = "http://blockchain.info/ticker";
$json = file_get_contents($api);
$data = json_decode($json, TRUE);
$rate = $data["USD"]["15m"];
$symbol = $data["USD"]["symbol"];
echo $rate.$symbol;
?>

Solve when i use curl
$url = "http://blockchain.info/ticker";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
$data = json_decode($result, TRUE);
$rate = $data["USD"]["15m"];
$symbol = $data["USD"]["symbol"];
echo $rate.$symbol;
thanks to all for support..

This method is not secure to perform a request to other server. You should use curl instead of file_get_contents. Btw, if still you want to keep this approach you can enable it in php.ini setting allow_url_fopen to 1

I have created an call back API to receive the JSON data but its not working

I have created a call back API to receive the JSON data after hitting my server. But somehow its not working as expected
This the response which i have to receive in my API
{"ERROR":0,"STATUS":1,"ORDERID":753093,"OPTRANSID":"2107938600"}
I have written the php file for this rcstatus.php
$url = 'http://softwarecompany.club/pks/recharge/b2b/rcstatus.php?status='.$_GET['status'].'&Orderid='.$_GET['Orderid'].'&Optransid='.$_GET['Optransid'];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 30000);
$data = curl_exec($ch);
echo $data;
$json = json_decode($url,true);
$json['STATUS'];
Please help me to achieve this. I have never worked with JSON data before. So please help me to achieve it. Thanks in advance!!!
You need to replace:
$json = json_decode($url,true);
with
$json = json_decode($data,true);
Replace $url to $data in last when you get the response like this.
$url = 'http://softwarecompany.club/pks/recharge/b2b/rcstatus.php?status='.$_GET['status'].'&Orderid='.$_GET['Orderid'].'&Optransid='.$_GET['Optransid'];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_TIMEOUT_MS, 30000);
$data = curl_exec($ch); // This is Your Response
$json = json_decode($data,true);
$json['STATUS'];

PHP Reading currency quotes when "allow_url_fopen=0"

I need a fresh EURUSD quote to show my product prices in a website.
I'm trying to read the quote from Yahoo finance with the following code:
$eurUsd = 1.3700; // Default value
$yahooUrl = 'http://finance.yahoo.com/d/quotes.csv?f=l1&s=EURUSD=X';
$handle = fopen($yahooUrl, 'r');
if ($handle) {
$result = fgetcsv($handle);
fclose($handle);
$eurUsd = $result[0];
}
This code works fine in my testing environment but not in my website since I have "allow_url_fopen=0". I do not want to change it for a security reason.
The request I'm using returns a string like:
1.3715
Do you know how I can read the string in other way?
Do you know an alternative way to access the EURUSD quote?
EDIT
Thanks to Epik's code I tried to use curl, but without success with Yahoo.
Finally I rid off Yahoo and succeed with Rate Exchange JSON/JSONP APIs
A working solution:
$url = 'http://rate-exchange.appspot.com/currency?from=EUR&to=USD';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
$eurUsd = json_decode($result)->{'rate'};
$ch = curl_init();
$url = 'http://finance.yahoo.com/d/quotes.csv?f=l1&s=EURUSD=X';
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);

Retrieve JSON using PHP from a URL

I am trying to hit an API and get some JSON back. I can’t seem to figure out what I am doing wrong here. I am getting null as the output.
Here is my PHP code:
<?php
$query_string_full = 'https://api.cityofnewyork.us/calendar/v1/search.htm?app_id=39563317lalaland&app_key=somethingsomething&categories=City%20Government%20Office';
$json = file_get_contents($query_string_full);
$obj = json_decode($json);
echo '<pre>'. json_encode($obj, JSON_PRETTY_PRINT) .'</pre>';
?>
The function file_get_contents doesn’t work with https. You should use the cURL functions instead.
<?php
$query_string_full = 'https://api.cityofnewyork.us/calendar/v1/search.htm?app_id=39563317&app_key=8396021a9bde2aad2eaf8ca9dbeca353&categories=City%20Government%20Office';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $query_string_full);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$json = curl_exec($ch);
curl_close($ch);
$obj = json_decode($json);
echo '<pre>'. json_encode($obj, JSON_PRETTY_PRINT) .'</pre>';
?>
I made this little function to return the json from a few different apis. You need to be using curl.
function exposeJSON ($apiUrl) {
$json_url = $apiUrl;
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $json_url);
// Built in authentication if needed.
//curl_setopt($ch, CURLOPT_USERPWD, "$USER:$PASS");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
// grab URL and pass it to the browser
$response = curl_exec($ch);
$return = json_decode($response[0], true);
// close cURL resource, and free up system resources
curl_close($ch);
return $return;
}
So you could do something like
$apiData = exposeJSON('urltoapi');
echo $apiData; // Should be the json.

cURL with PHP - HTTP cURL to HTTPS

I have the following bit of PHP, it works locally (via apache and localhost) but not on my hosting - $response is always empty:
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$api_key = 'my_api_key';
$randomString = generateRandomString(10);
$endLabel = sha1(md5($randomString));
$user_id = $endLabel;
$amount_doge = '5';
$url = "https://dogeapi.com/wow/?api_key=".$api_key."&a=get_new_address&address_label=".$user_id;
$response = get_data($url);
I wondered if this could be because I'm hosted on HTTP (no SSL option) and I'm calling a HTTPS domain? If so, is there a way around this? I've tried curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); but it doesn't seem to do anything :(
try to use echo curl_error($ch) after $data = curl_exec($ch); to see what curl says
it wil lreport you what happened

php youtube json decode

I tried to use JSON decode to get the youtube API feed. However, when I paste the JSON result in http://www.jsonlint.com/ I noticed something like
"media$group": {
"media$category": [
Unfortunately some symbols are rejected by php. Here is my code, I tried to remove this $ symbol, but maybe not success. How do I solve this?
$url = 'http://gdata.youtube.com/feeds/api/videosq=football&orderby=published&v=2&alt=json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
$body1 = curl_exec($ch);
$body = str_replace('$','', $body1);
curl_close($ch);
$data = json_decode($body);
foreach ($data->feed->entry as $result) {
...
}
Your problem is the usage of PHP identifiers to access the contents. The simplest solution here would be to get an array instead of an object:
$data = json_decode ( $json , $assoc = true );
This allows access to fields with:
echo $result['media$group']['media$description'];
If you want to keep the object syntax, that's possible with this kludge:
echo $result->{'media$group'}->{'media$category'};
(But arrays are safer here. You don't get a fatal error should the format change and properties be absent.)
This work:
<?php
$url = 'http://gdata.youtube.com/feeds/api/videos?q=football&orderby=published&v=2&alt=json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $url);
$body1 = curl_exec($ch);
$body = str_replace('$','', $body1);
curl_close($ch);
$data = json_decode($body);
foreach ($data->feed->entry as $result) {
var_dump($result);
}
?>
