I'm trying to get current USD/EUR rate using this api link:
http://api.fixer.io/latest?base=USD&symbols=EUR
Using this code:
$url = "http://api.fixer.io/latest?base=USD&symbols=EUR";
$json = json_decode(file_get_contents($url), true);
$price = $json->rates[0]->EUR;
I want result of $price to be like: "0.84782",
but it seems I'm doing something wrong?
<?php
$url = "http://api.fixer.io/latest?base=USD&symbols=EUR";
$json = json_decode(file_get_contents($url), true);
$price=$json['rates']['EUR'];
echo $price;
This will work for you. The price you are looking for is a nested array so you must first access the parent one.
You are passing true to json_decode, so the returned value is an array. To use object instead, remove true, like so:
$json = json_decode(file_get_contents($url));
Access it like this:
echo $json->rates->EUR; // Output is: 0.84782
If you want to access array style:
$json = json_decode(file_get_contents($url), true);
echo $json['rates']['EUR']; // 0.84782

I want to fetch data(the images in each post) stored in https://www.instagram.com/explore/tags/selfie/?__a=1, but all I get when I decode and var_dump this is NULL.
$obj = json_decode("https://www.instagram.com/explore/tags/selfie/?__a=1", true);
var_dump($obj);
Before decoding json you have to first fetch api response.
$obj = json_decode(file_get_contents("https://www.instagram.com/explore/tags/selfie/?__a=1"), true);
You're trying to json_decode the STRING
https://www.instagram.com/explore/tags/selfie/?__a=1
What you need to do is to fetch the URL first. I suggest using file_get_contents, which takes a URL and returns the contents at the end of that URL.
Try this:
$json = file_get_contents("https://www.instagram.com/explore/tags/selfie/?__a=1");
$obj = json_decode($json, true);
var_dump($obj);
The argument to the function json_decode(), $html must be plaintext/string.
This should work.
$url = "https://www.instagram.com/explore/tags/selfie/?__a=1";
$html = file_get_contents($url);
$obj = json_decode($html,true);
var_dump($obj);

I have a json object from a curl get request.
// Curl Stuff
$resp = curl_exec($curl);
{"food": {"id":585897,"foodGroup":"meats","calories":1109,"foodTier":30}}
I saved it in a variable with json_decode
$data = json_decode($resp, TRUE);
I've tried accessing the data in a couple ways but I get no response
echo $data[0][1];
echo $data[0]['id'];
Also if someone can point me in the right direction of looping through this data I would appreciate that.
With the true parameter in your json_decode, you have associative array, so it must be:
echo $data['food']['id'];
Get the id by numeric:
$da = array();
foreach($data as $key=>$val){
$da[$key] = array_values($val);
}
print_r($da);
echo $da['food'][0];
I'm trying to get data onto my website by parsing data from a JSON format. The URL is http://api.bfhstats.com/api/onlinePlayers and I'm trying to output for example the currently players online on PC.
Here's the current code I have:
<?$json = file_get_contents("http://api.bfhstats.com/api/onlinePlayers");
$data = json_decode($jsondata, true);
echo $data->pc->peak24;?>
I thought this would work, however it's not displaying anything. I am very new to parsing JSON data so if someone could explain what I'm doing wrong that would be brilliant.
change:
$data = json_decode($jsondata, true);
to
$data = json_decode($json, true);
Also, json_decode returns an array so use:
echo $data['pc']['peak24'];
to access the data.
You first call the variable $json but then use $jsondata in json_decode.
You are missing the foreach cycle to fetch the two dimensional array $data:
<?php
$json = file_get_contents("http://api.bfhstats.com/api/onlinePlayers");
$data=array();
$data = json_decode($json, true);
//print_r ($data);
foreach ($data as $pc) {
echo $pc["peak24"]."<br>";
}
?>
Check the $json and $jsondata that have different name but should be the same.
json response as below:
{"Success":true,"ErrorCode":0,"UserInformation":{"UserID":"19"}......
how do I get the UserID value by using json_decode?
I tried the below code with no luck.
$Response = json_decode($Response[2]);
echo $Response[0][0][0];
This should work:
<?php
$json = '{"Success":true, "ErrorCode":"0","UserInformation":{"UserID":"19"}}';
$response = json_decode($json, true);
echo $userId = $response["UserInformation"]["UserID"];
?>
Please check the PHP documentation of json_decode at http://php.net/json_decode
You can use object as well if you skip the second parameter of the json_decode function.
I'm trying to turn a JSON file of Xbox Live data into variables that I can use in a PHP generated image. My JSON file is here: http://www.xboxgamercard.org/gamercard/test3/xbox.php
I have tried this:
$request_url = 'xbox.php';
$json = file_get_contents($request_url);
$decode = json_decode($json, true);
var_dump($decode['gamertag'][0]);
but it just returns NULL.
I would like to use the JSON as shown here:
$gamertag = $data['Gamertag'];
echo $gamertag;
You need to add the full url eg:
<?php
$request_url = 'http://www.xboxgamercard.org/gamercard/test3/xbox.php';
$json = file_get_contents($request_url);
$data = json_decode($json, true);
//Example output
echo $data['gamertag']; //Crylics
echo $data['gamerscore']; //7492
/* Too access the recent_games key you will need
to loop through it or access it like
*/
echo $data['recent_games'][1]['title']; //Call of Duty: WaW
?>
