I have a json i am fetching remotely in php,
the Json returned is as follow:
{
"base_currency_code":"USD",
"base_currency_name":"United States dollar",
"amount":"1.0000",
"updated_date":"2022-01-30",
"rates":{
"KWD":{
"currency_name":"Kuwaiti dinar",
"rate":"0.3030",
"rate_for_amount":"0.3030"
}
},
"status":"success"
}
the i try to get the specific value from key : rate :
$url='https://...';
$json = file_get_contents($url);
$obj = json_decode($json,true);
echo $obj['rates']['KWD']['rate'];
but I have no output, when I would like to have 0.3030. Why is this?
test.json
{
"base_currency_code":"USD",
"base_currency_name":"United States dollar",
"amount":"1.0000",
"updated_date":"2022-01-30",
"rates":{
"KWD":{
"currency_name":"Kuwaiti dinar",
"rate":"0.3030",
"rate_for_amount":"0.3030"
}
},
"status":"success"
}
test.php
<?php
$url='test.json';
$json = file_get_contents($url);
$obj = json_decode($json,true);
echo $obj['rates']['KWD']['rate'];
Result 0.3030
If it is not working, you cannot access the site remotely.
try it and make sure it works
<?php
$url='https......';
$json = file_get_contents($url);
echo $json;

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've a JSON string, I want to get it in store of Extjs by a PHP url. How to get this string as a JSON from a php file. Something like this:
Extjs file:
PHP file:
The result is blank.
What I do now for this work?
An example of what I believe you mean to do:
$array = array();
$test = '{ "firstName":"John" , "lastName":"Doe" }';
$array[] = json_decode($test);
$test = '{ "firstName":"Jane" , "lastName":"Doe" }';
$array[] = json_decode($test);
$test = '{ "firstName":"Random" , "lastName":"Guy" }';
$array[] = json_decode($test);
print json_encode($array);
exit;
Will give you:
[{"firstName":"John","lastName":"Doe"},{"firstName":"Jane","lastName":"Doe"},{"firstName":"Random","lastName":"Guy"}]
As for the Ajax, maybe this will help - How to get "data" from JQuery Ajax requests, or maybe try the Jquery Ajax documentation.
I'm having difficulties grabbing any of the JSON information from this URL.
I've tried other JSON snippets and they seem to work so I'm not sure if it's the way that the URL is structured or something.
Basic example below.
<?php
$json = file_get_contents('http://nhs-sh.cfpreview.co.uk/api/version/fetchLatestData?dataType=Clinics&versionNumber=-1&uuID=website&dt=');
$obj = json_decode($json);
echo "Body: " . $obj->Body;
?>
The link provided starts with
{ data :
which is valid javascript but invalid json. You can test it on http://jsonlint.com. To fix this we can replace the data with "data" :
$json = file_get_contents('http://nhs-sh.cfpreview.co.uk/api/version/fetchLatestData?dataType=Clinics&versionNumber=-1&uuID=website&dt=');
$obj = json_decode($json);
if (json_last_error() !== JSON_ERROR_NONE) { //check if there was an error decoding json
$json = '{ "data" :'. substr(trim($json), 8); // replace the first 8-1 characters with { "data" :
$obj = json_decode($json);
}
print_r($obj->data); //show contents of data
Please note that this fix is dependent on the data source e.g. if they change data to dataset. The correct measure would be to ask the developers to fix their json implementation.
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.
<?php
$handle = fopen("https://graph.facebook.com/search?q=sinanoezcan#hotmail.com&type=user&access_token=2227472222|2.mLWDqcUsekDYK_FQQXYnHw__.3600.1279803900-100001310000000|YxS1eGhjx2rpNYzzzzzzzLrfb5hMc.", "rb");
$json = stream_get_contents($handle);
fclose($handle);
echo $json;
$obj = json_decode($json);
print $obj->{'id'};
?>
Here is the JSON: {"data":[{"name":"Sinan \u00d6zcan","id":"610914868"}]}
It echos the JSON but I was unable to print the id.
Also I tried:
<?php
$obj = json_decode($json);
$obj = $obj->{'data'};
print $obj->{'id'};
?>
Note that there is an array in the JSON.
{
"data": [ // <--
{
"name": "Sinan \u00d6zcan",
"id": "610914868"
}
] // <--
}
You could try $obj = $obj->{'data'}[0] to get the first element in that array.
data is an array, so it should be:
print $obj[0]->{'id'};
It looks like the key "data" is an array of objects, so this should work:
$obj = json_decode($json);
echo $obj->data[0]->name;
Have you tried $obj->data or $obj->id?
Update: Others have noted that it should be $obj->data[0]->id and so on.
PS You may not want to include your private Facebook access tokens on a public website like SO...
It's a bit more complicated than that, when you get an associative array out of it:
$json = json_decode('{"data":[{"name":"Sinan \u00d6zcan","id":"610914868"}]}', true);
Then you may echo the id with:
var_dump($json['data'][0]['id']);
Without assoc, it has to be:
var_dump($json->data[0]->id);
