I have a problem with starting a project of 'clan community statistics'.
I have a URL with the API of the statistics, and i want to show this in an array using a simple html dom parser. I want to get this effect:
{
"status": "ok",
"count": 1,
"data": {
"1": {
"members_count": 100,
"description": "Закрытый клан...",
"description_html": "<p>Закрытый клан....\n</p>",

},

"role": "private",
"updated_at": 1375930001,
"account_id": 196632,
"account_name": "Wrobel"
},
"18458": {
"created_at": 1360836543,
"role": "diplomat",
"updated_at": 1375930001,
"account_id": 18458,
"account_name": "alienraven"
},
"3100": { ....
}
},
"motto": "Орлы! Орлицы!",
"clan_color": "#e18000",
"owner_id": 1277137
}
}
}
My code
include('simple_html_dom.php');
$html = file_get_html('http://api.worldoftanks.eu/2.0/clan/info/?application_id=d0a293dc77667c9328783d489c8cef73&clan_id=500009659');
...?
What should I do next to prepare an array and display it in the way which I want on my web page? Is there someone obliging to explain it to me? please.
Greetings Mary
try this
<?php
// example of how to modify HTML contents
include('../simple_html_dom.php');
// get DOM from URL or file
$html = file_get_html('http://api.worldoftanks.eu/2.0/clan/info/?application_id=d0a293dc77667c9328783d489c8cef73&clan_id=500009659');
$data = json_decode($html);
echo "<pre>";
print_r($data);
?>
I see the data is in json format. Just use:
$json = file_get_contents('http://api.worldoftanks.eu/2.0/clan/info/?application_id=d0a293dc77667c9328783d489c8cef73&clan_id=500009659'); //gets the json
$obj = json_decode($json); //decode the json into object or array. You'll get an object
var_dump($obj); //view the object. Parse the object the way you want to.

In one of my applications I get a JSON format response data from a REST API. Which is as similar as the following:
{
"Response": {
"user_id": "12003",
"username": "Shimul",
"status": "active"
},
"ErrorMessage": "",
"Status": 0
}
From this response, I just need to fetch user_id to process further operations in my application. But I can't identify how to decode this using PHP json_decode()
Can anyone tell me how can I decode this using PHP and fetch only user_id from this response?
Thanks
json_decode take 2 parameters.
(string) json
(bool) assoc. If TRUE, the function will return array else object.
so you just need to do is:
<?php
$json = '{
"Response": {
"user_id": "12003",
"username": "Shimul",
"status": "active"
},
"ErrorMessage": "",
"Status": 0
}';
// By converting into array..
$array = json_decode($json,TRUE);
$user_id = $array['Response']['user_id'];
//---------OR---------
// Using Object
$obj = json_decode($json);
$user_id = $obj->Response->user_id;
?>
I hope this will help.
You don't show us what you tried so far and why it failed, but it's as simple as that:
<?php
$json = '{
"Response": {
"user_id": "12003",
"username": "Shimul",
"status": "active"
},
"ErrorMessage": "",
"Status": 0
}';
var_dump(json_decode($json)->Response->user_id);
As a test, this JSON data is being POSTed to my website:
{
"order": {
"id": null,
"created_at": null,
"status": "new",
"total_btc": {
"cents": 100000000,
"currency_iso": "BTC"
},
"total_native": {
"cents": 2263,
"currency_iso": "USD"
},
"custom": "123456789",
"button": {
"type": "buy_now",
"name": "Test Item",
"description": null,
"id": null
},
"transaction": {
"hash": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
"confirmations": 0
}
}
}
Since it is being sent server-to-server I cannot visibly see the data. I have tried sending the $_POST array to a text file, but it comes up blank. What I think I need to do is:
$data = json_decode($jsonData);
But how do I set the variable $jsonData?
You can try to use wrappers for reading raw POST query.
$data = file_get_contents("php://input");
Have you tried this, store the sting obtained to a variable and then decoding it?
$postedJsonData= '{"order":{"id":null,"created_at":null,"status":"new","total_btc":
{"cents":100000000,"currency_iso":"BTC"},"total_native":
{"cents":2263,"currency_iso":"USD"},"custom":"123456789","button":
{"type":"buy_now","name":"Test Item","description":null,"id":null},"transaction":
{"hash":"4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b","confirmations":0}}}';
var_dump(json_decode($postedJsonData, true));
The true parameter would return an associative array
$data = json_decode($jsonData, True);

I tried using below code,
it doesn't work.
$json = json_decode($body);
echo $json->ISBN:9780980200447->info_url;
It's giving an error..
Is there any other easy way to read all elements?
You are on the right track. : is just an invalid character for a property and must be handled special.
echo $json->{'ISBN:9781430215752'}->info_url;
will get you the expected result.
You may also decode as an associative array
$json = json_decode($body, true);
echo $json['ISBN:9781430215752']['info_url'];
I would probably stick to this approach rather than the object oriented, since encapsulating keys makes code less readable
You must use
echo $json->{'ISBN:9780980200447'}->info_url;
since 'ISBN:9780980200447' is your class name.
Reference: php.net
<?php
$json = '{"foo-bar": 12345}';
$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345
?>
Use braces like this:
echo $json->{'ISBN:9781430215752'}->info_url;
I a trying to decode a json callback.
The json code is posted to callback.php - Here is an example of the json:
{
"order": {
"id": "5RTQNACF",
"created_at": "2012-12-09T21:23:41-08:00",
"status": "completed",
"total_btc": {
"cents": 100000000,
"currency_iso": "BTC"
},
"total_native": {
"cents": 1253,
"currency_iso": "USD"
},
"custom": "order1234",
"receive_address": "1NhwPYPgoPwr5hynRAsto5ZgEcw1LzM3My",
"button": {
"type": "buy_now",
"name": "Alpaca Socks",
"description": "The ultimate in lightweight footwear",
"id": "5d37a3b61914d6d0ad15b5135d80c19f"
},
"transaction": {
"id": "514f18b7a5ea3d630a00000f",
"hash": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
"confirmations": 0
},
"customer": {
"email": "coinbase#example.com",
"shipping_address": [
"John Smith",
"123 Main St.",
"Springfield, OR 97477",
"United States"
]
}
}
}
I can echo the json and get the following response:
{"order""id":null,"created_at":null,"status":"completed","total_btc":{"cents":100000000,"currency_iso":"BTC"},"total_native":{"cents":83433,"currency_iso":"USD"},"custom":"123456789","receive_address":"1A2qsxGHo9KjtWBTnAopTwUiBQf2w6yRNr","button":{"type":"buy_now","name":"Test Item","description":null,"id":null},"transaction":{"id":"52d064b59eeb59985e00002c","hash":"4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b","confirmations":0}}}
However if I try to decode the json using the following:
$array = json_decode($jsonString, true);
echo $array;
I get the following response: "200 Array"
I want to be able turn each json parameter in to a php variable.
You can access the variables within $array, for example by doing:
echo $array['custom']; // prints out "order1234"
You don't want to extract the variables directly into the local lexical scope of your program as that would create security concerns. Just use the data as indicated in the snippet above.
As a test, this JSON data is being POSTed to my website:
{
"order": {
"id": null,
"created_at": null,
"status": "new",
"total_btc": {
"cents": 100000000,
"currency_iso": "BTC"
},
"total_native": {
"cents": 2263,
"currency_iso": "USD"
},
"custom": "123456789",
"button": {
"type": "buy_now",
"name": "Test Item",
"description": null,
"id": null
},
"transaction": {
"hash": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
"confirmations": 0
}
}
}
