I want to get price of btc to usd using coinmarketcap's API.
$response = curl_exec($curl); // Send the request, save the response
$type = json_decode($response,true);
Getting 200 Ok response
"data": {
"symbol": "BTC",
"id": "1",
"name": "Bitcoin",
"amount": 50,
"last_updated": "2018-06-06T08:04:36.000Z",
"quote": {
"USD": {
"price": 284656.08465608465,
"last_updated": "2018-06-06T06:00:00.000Z"
},
I want to get Price value from usd but its not working when i tried
$examount = $type->USD->price;
Since you are using
$response = curl_exec($curl); // Send the request, save the response
$type = json_decode($response,true);
It means that your object is converted to associative array,
to access the price use:
$type['data']['quote']['USD']['price'];
You should be good to go.
Edit
In case $type contains more than one element, you will need to loop them.
foreach($type['data'] as $singleQuote){
$price = $singleQuote['quote']['USD']['price'];
echo 'Quote for: '.$singleQuote['symbol'].' in USD: '.$price.'<br/>';
}
Because you are passing 2nd param true that will convert it to associative array:
$response = curl_exec($curl); // Send the request, save the response
$type = json_decode($response,true);
$examount = $type['data']['quote']['USD']['price'];
I hope above will solve your problem as per the documentation of coinmarketcap (https://coinmarketcap.com/api/documentation/v1/#section/Endpoint-Overview)
the problem was cuased by the $request was returning null all of above are correct also

I'm trying to decode JSON format
My API Endpoint is https://api.reliableserver.host/api/landings
And this is the output
{
"success": true,
"data": [
{
"id": 1,
"primary_balance": "$4,184.37",
"primary_currency": "USD",
"secondary_balance": "¥0",
"secondary_currency": "JPY",
"tertiary_balance": "฿0.00",
"tertiary_currency": "THB",
"first_language": "ไทย",
"second_language": "English",
"footer_text": "a",
"created_at": "2020-10-26T07:45:49.000000Z",
"updated_at": "2020-10-28T05:31:04.000000Z",
"deleted_at": null
}
],
"message": "Landings retrieved successfully"
}
I need to echo individual values, for example: Primary Balance: $4,184.37
I tried using this:
$url = "https://api.reliableserver.host/api/landings";
$obj = json_decode($url);
echo $obj>primary_balance;
But it didnt work, kindly guide me what am I doing wrong.
You can do this way :
$url = '{"success": true,"data": [{"id": 1,"primary_balance": "$4,184.37","primary_currency": "USD","secondary_balance": "¥0","secondary_currency": "JPY","tertiary_balance": "฿0.00","tertiary_currency": "THB","first_language": "ไทย","second_language": "English","footer_text": "a","created_at": "2020-10-26T07:45:49.000000Z","updated_at": "2020-10-28T05:31:04.000000Z","deleted_at": null}],"message": "Landings retrieved successfully"}';
$obj = json_decode($url, true);
echo $obj['data'][0]['primary_balance'];
// output $4,184.37
Above code tested here
You need file_get_contents() method to get the JSON data from your given URL.
$url = "https://api.reliableserver.host/api/landings";
$obj = json_decode(file_get_contents($url), true);
echo $obj['data'][0]['primary_balance'];
// output $4,184.37
Basically, you are not calling that api anywhere. If it is an open endpoint (without auth or headers, you can do file_get_contents() or I suggest you to use curl.
Also, you need to check on response data structure, it has a 'data' key which is an array. so you need to use foreach to iterate on the 'data' key.
I have given a sample answer that should work if there is only 1 item in data.
$url = "https://api.reliableserver.host/api/landings";
$resp = file_get_contents($url);
$obj= json_decode($resp);// will return in object form
echo $obj->data[0]->primary_balance;
or
$url = "https://api.reliableserver.host/api/landings";
$resp = file_get_contents($url);
$obj= json_decode($resp, true); // will return in array form
echo $obj['data'][0]['primary_balance'];
json_decode()
I have a string that i get from an API and i wish i could put it in a array so i could check the values that came from the return.
String return example:
{
"code":"000",
"message":"XXX",
"date":"2018-05-17",
"hour":"09:16:09",
"revision":"",
"server":"XX",
"content":{
"nome":{"info":"SIM","conteudo":[{"field1":"XXXX","field2":"XX"}]}
}
}
What I need:
echo $string['code'];
Javascript has no problem with JSON encode command. But how can I do it with PHP?
First of all your JSON data seems to be invalid (Some brackets missing). It needs to be like this:-
{
"code": "000",
"message": "XXX",
"date": "2018-05-17",
"hour": "09:16:09",
"revision": "",
"server": "XX",
"content": {
"nome": {
"info": "SIM",
"conteudo": [{
"field1": "XXXX",
"field2": "XX"
}]
}
}
}
Now You need to decode this JSON data and then get data based on the index
$array = json_decode($json,true);
echo $array['code'];
Output:-https://eval.in/1005949
You can decode the JSON string to Array in PHP.
$str = '{"code":"000","message":"XXX","date":"2018-05-17","hour":"09:16:09","revision":"","server":"XX","content":{"nome":{"info":"SIM","conteudo":[{"field1":"XXXX","field2":"XX"}]}';
$decodedValue = json_decode($str, true);
var_dump($decodedValue);
Your example string is not valid json, you are missing some closing brackets.
This should be the correct way:
'{"code":"000","message":"XXX","date":"2018-05-17","hour":"09:16:09","revision":"","server":"XX","content":{"nome":{"info":"SIM","conteudo":[{"field1":"XXXX","field2":"XX"}]}}}'
As for your question. in PHP you can easily use json_decode
Example:
<?php
$json = '{"code":"000","message":"XXX","date":"2018-05-17","hour":"09:16:09","revision":"","server":"XX","content":{"nome":{"info":"SIM","conteudo":[{"field1":"XXXX","field2":"XX"}]}}}';
$decoded_json = json_decode($json, true);
echo $decoded_json['code'];
You can see it working here
After executing CURL I am getting the $result variable value as:
{
"ErrorCode": "000",
"ErrorMessage": "Success",
"JobId": "6878b812-766d-48a2-9dae-2b0edf2d84d4",
"MessageData": [{
"Number": "919730842844",
"MessageParts": [{
"MsgId": "919730842844-64a40d7611f94c03bea1045fdfa9bac5",
"PartId": 1,
"Text": "\u0027messagecontentsmstest\u0027"
}]
}]
}
Now i need to check for the ErrorCode == 000, so how can I get the value of individually ErrorCode?
This response received is like JSON.
So I thought to decode it as an json_decode:
$chk = json_decode($result);
echo $chk->ErrorCode;
or we can even try in another way like,
$array = json_decode($result, true);
echo $array['ErrorCode'];
I have added new data to my API. I want to return it as plain text
This is the API response PHP returns.
{
"apiVersion":"1.0",
"data":{
"location":"London",:
{
"pressure":"1021",
"temperature":"23",
"skytext":"Sky is Clear",
"humidity":"40",
"wind":"18.36 km/h",
"date":"07-10-2015",
"day":"Friday"
}
}
I want to return the pressure value on my html page so my users can see the reading. I am having issues displaying it.
This is my PHP api.php
require_once('./includes/config.php');
require_once('./includes/functions.php');
error_reporting(0);
header('Content-Type: text/plain; charset=utf-8;');
$city = $_GET['city'];
if(isset($city)) {
$weather = new Weather($conf['apikey'], $_GET['f']);
$weather_current = $weather->get($city, 0, 0, null, null);
$now = $weather->data(0, $weather_current);
if($now['location'] !== NULL) {
echo '{"apiVersion":"1.0", "data":{ "location":"'.$now['location'].'", "temperature":"'.$now['temperature'].'", "pressure":"'.$now['pressure'].'", "skytext":"'.$now['description'].'", "humidity":"'.$now['humidity'].'", "wind":"'.$now['windspeed'].'", "date":"'.$now['date'].'", "day":"'.$now['day'].'" } }';
} else {
echo '{"apiVersion":"1.0", "data":{ "error":"The \'city\' requested is not available, make sure it\'s a valid city." } }';
}
} else {
echo '{"apiVersion":"1.0", "data":{ "error":"You need to specify the city parameter" } }';
}
In order to fetch data from a JSON source you should parse the data with the json_decode() method. You can then use the second parameter to parse it into an array. If you omit the second parameter you would get an array of objects.
Important: It seems your JSON has a syntax error too. I have added a weather key before the weather information.
$data = '{
"apiVersion":"1.0",
"data":{
"location":"London",
"weather":{ // Notice the new key!
"pressure":"1021",
"temperature":"23",
"skytext":"Sky is Clear",
"humidity":"40",
"wind":"18.36 km/h",
"date":"07-10-2015",
"day":"Friday"
}
}
}';
$json = json_decode($data, true);
You should then be able to fetch the pressure as an associative array.
$pressure = $json['data']['weather']['pressure']; // Equals: 1021
Hope this can help you, happy coding!
First of all, you need to validate your JSON. It is missing some key things that will keep you from being able to parse it. Use JSONLint to verify your JSON.
After modification the JSON to make it valid I did the following:
$json = '{"apiVersion":"1.0", "data":{ "location":"London", "data":{ "pressure":"1021", "temperature":"23", "skytext":"Sky is Clear", "humidity":"40", "wind":"18.36 km/h", "date":"07-10-2015", "day":"Friday" }}}';
$obj_style = json_decode($json);
$array_style = json_decode($json, true);
echo $obj_style->data->data->pressure;
echo $array_style['data']['data']['pressure'];
Using json_decode() I was able to setup a way to parse the JSON two ways, once as an object and once as an array (adding the true flag returns the results as an array).
From there all you have to do is drill town to the bits of information that you want to display.
I have json from stripe and I am trying to decode it json_decode.
I am not getting an error. Just nothing is returning. I am getting the data back from stripe, I just cant decode it.

// retrieve the request's body and parse it as JSON
$body = #file_get_contents('php://input');
$event_json = json_decode($body,true);
print_r($event_json);
Any ideas?
The php://input stream allows you to read raw data from the request body. This data will be a string and depending on what sort of values are in the request, will look something like:
"name=ok&submit=submit"
This is not JSON and therefore won't decode as JSON the way you expect.The json_decode() function returns null if it can't be decoded.
Where are you getting the JSON you posted above? That is the value you need to pass into json_decode().
If JSON is being passed in the request, like in the instance of callbacks, you would still need to parse that portion out to get just the JSON. If the php://input stream gives you name=ok&submit=submit&json={"created": 1326853478} then you'd have to parse it out. You can use this function from the PHP manual to seperate the values to work like the $_POST array:
<?php
// Function to fix up PHP's messing up POST input containing dots, etc.
function getRealPOST() {
$pairs = explode("&", file_get_contents("php://input"));
$vars = array();
foreach ($pairs as $pair) {
$nv = explode("=", $pair);
$name = urldecode($nv[0]);
$value = urldecode($nv[1]);
$vars[$name] = $value;
}
return $vars;
}
?>
To use it:
$post = getRealPOST();
$stripe_json = $post['json'];
$event_json = json_decode($stripe_json);
Here, I ran this:
<?php
$data = '{ "created": 1326853478, "data": { "object": { "amount": 4500, "card": { "country": "US", "cvc_check": "pass", "exp_month": 7, "exp_year": 2014, "fingerprint": "9aQtfsI8a17zjEZd", "id": "cc_00000000000000", "last4": "9782", "object": "card", "type": "Visa" }, "created": 1322700852, "currency": "usd", "disputed": false, "fee": 0, "id": "ch_00000000000000", "livemode": false, "object": "charge", "paid": true, "refunded": true } }, "id": "evt_00000000000000", "livemode": false, "type": "charge.refunded" }';
$arr = json_decode($data, true);
print_r($arr);
?>
And it worked. So, theoretically you should be able to use:
<?php
$arr = json_decode(file_get_contents('php://input'), true);
print_r($arr);
?>
As Ignacio Vazquez-Abrams said, don't use the '#' character because it obscures error messages and makes it harder to debug.
I would also check what version of PHP you have. json_decode() is only available on version 5.2.0 and later.
