This is how decode the JSON, I'm able to get 'uuid'
$raw = file_get_contents('php://input');
$json = json_decode($raw, true);
I tried with
foreach ($json->formats as $format) {
$url = $format["thumbnail_url"];
}
and
$url = $json->formats[0]->thumbnail_url
and
$url = $json['formats']['thumbnail_url']
but I'm still unnable to get the right value. I'm I missing something?
You just about had its $url = $json['formats'][0]['thumbnail_url']
$json is a nested array. $json['formats'] is an array of objects, to get the first object use $json['formats'][0]
You can easily see what is in $json with var_export($json) or print_r($json)

I have this json code
"result": [
{
"update_id": 74783732,
"message": {
"message_id": 852,
"from": {
"id": ---,
"is_bot": false,

},
"chat": {

"text": "#username",
"entities": [
{
"offset": 0,
"length": 16,
"type": "mention"
}
]
}
}
]
I can get content from update_id , message, first_name etc.
but I want to get "mention" from type how can i do it?
my code is
here i decode json and get arrays from json and put them in variable and use it in my queries but I cant get mention from entities...
$update = file_get_contents("php://input");
$update_array = json_decode($update, true);
if( isset($update_array["message"]) )
{
$text = $update_array["message"]["text"];
$chat_id = $update_array["message"]["chat"]["id"];
}
if(isset($update_array["message"]["entities"]["type"]) and $update_array=="mention")
{
$get_username = $text;
show_users_by_username($get_username);
}
tnx for helping
$update_array will never be equal to "mention" but $update_array["message"]["entities"]["type"] yes.
Change your condition.

Here's my php code so far. I've tried quite a few different things. I normally use xml feeds which seem to be easy for me to setup for what I need. I'm not sure what I'm missing here.
$url = 'https://whatever.com/api/external/v4/widget?userId=whatever&tag=featured'; // path to your JSON file
$data = file_get_contents($url); // put the contents of the file into a variable
$performers = json_decode($data, true); // decode the JSON feed
foreach ($performers as $performer) {
$info = $performer[0]["username"];
echo $info;
}
I'm only getting the first username and then error messages.
Warning: Illegal string offset 'username' in /whatever
Can anyone help with this?
You should use $performers['models'] array in foreach and then get username it will work fine try the following code
$performers = json_decode($data, true);
if(isset($performers['models'])){
foreach ($performers['models'] as $performer) {
$info = (isset($performer["username"])) ? $performer["username"] : '';
echo $info;
echo "<br>";
}
}
Output
model1
model2
I'm using Giscloud's REST API to grab a json with some info that i need for my web app. The problem is that it seems impossible that I can fetch and/or decode any data from that json using the corresponding php functions. I think it has something to do with the way the json file is structured.
This is the json file (some fields edited):

These are the different ways that i've tried to decode this json and put it into a variable.
$json = curl_exec($ch);
// Number 1
$data = var_dump(json_decode($json));
echo $data['data'][0]['id'];
exit;
// Number 1 returns
object(stdClass)[21]
public 'code' => string 'FATAL' (length=5)
public 'msg' => string 'Internal error' (length=14)
// Number 2
$data = json_decode($json,true);
echo $data['data'][0]['id'];
// Number 2 returns
PHP Undefined index: data
I've tried several other similar functions, like print_r. Or change some values there and here, but nothing has worked.
I would appreciate a lot some help on this!
Some extra info:
There's no problem with curl. It executes correctly.
Yes, the server answers with a json file.
UPDATE
Using json_last_error() (no need of parameters) I was able to debbug. The function returns an int depending of the type of error. Mine was 0meaning that there's no error.
I think I ran out of ideas for this.
Loose the var_dump() thats just for debugging and it is stoppping the json_decode() from returning a PHP Object from the json_decode().
Then use the correct object syntax to address the object
$json = curl_exec($ch);
$data = json_decode($json);
// debug code
if ( json_last_error() > 0) {
echo json_last_error_msg();
} else
// this should print the data structure
print_r($data);
}
// end debug code
echo $data->data[0]->id;
If you want all the id's from all the occurances you can do
$json = curl_exec($ch);
$data = json_decode($json);
foreach ($data->data as $idx => $obj ){
echo "Occurance $idx = " . $obj->id;
}
Object syntax:
$json = curl_exec($ch);
$json_data = json_decode($json);
foreach ( $json_data->data as $data_item){
echo '<p>ID: ' . $data_item->id . ' -- Name: ' . $data_item->name . '</p>';
}
Array Syntax:
Get the data as an associated array by adding a second parameter TRUE to json_decode() php docs
$json = curl_exec($ch);
$data_array = json_decode($json, true);
foreach ( $data_array['data'] as $item){
echo '<p>ID: ' . $item['id'] . ' -- Name: ' . $item['name'] . '</p>';
}
i dont preferable to use cURL In this situation , you can use
file_get_contents
so here is a simple code
$userdata = json_decode(file_get_contents("JSON_URL_GOES_HERE"), true)
$u_ID = $userdata['data'][0]['id'];
and so on
see :file_get_contents
I have an URL that returns the JSON object below:
{
"addressList": {
"addresses": [
{
"id": 0000000,
"receiverName": "Name Example",
"country": {
"id": "BRA",
"name": "Brasil"
},
"state": {
"id": "SP"
},
"city": "São Paulo",
"zipcode": "00000000",
"type": "Residential",
"street": "000, St Example",
"number": 00,
"neighborhood": "Example",
"hash": "1bf09357",
"defaultAddress": false,
"notReceiver": false
}
]
}
}
I want to get the state value, how can I retrieve that with PHP?
I tried, something like this, but I couldn't get the state value, that should be SP in this case.
$string = '{ "addressList": { "addresses": [ { "id": xxxxxx, "receiverName": "XXXXX XXXXX", "country": { "id": "BRA", "name": "Brasil" }, "state": { "id": "SP" }, "city": "São Paulo", "zipcode": "03164xxx", "type": "Residential", "street": "Rua xxx", "number": xx, "neighborhood": "xxxxx", "hash": "xxxxx", "defaultAddress": false, "notReceiver": false } ] } }';
$json_o = json_decode($string);
$estado = $json_o->state;
How can I achieve the result I want?
Your JSON is not valid - you can validate it on jsonlint.com (it's invalid due to incorrectly formatted numeric values - "id" : 000000).
From then on, you can decode the value and access your data:
$json_o = json_decode($string);
$estado = $json_o->addressList->addresses[0]->state->id;
If you don't have access to the code that generates the JSON, you can attempt to run a regex to match, replace & wrap the numerical values with ":
$valid_json = preg_replace("/\b(\d+)\b/", '"${1}"', $str);
Note: The above is just an example - you'll have to figure out a case where a numerical value is already wrapped by ".
Your JSON has a couple of syntax errors:
"id": 0000000
"number": 00
JSON doesn't support leading zeros. If precise formatting is important, use strings:
"number": "00"
"id": "0000000"
Alternatively, use well-formed integers in the JSON (saves space) and convert them to formatted strings in PHP.
Once you've fixed your JSON, you can access the state->id value of the first address as I do below. When you decode JSON from an untrusted source, be prepared to do some error handling:
$json_string ="..."; //your source, to be decoded
$json_o= json_decode($json_string);
if(is_null($json_o)): //there was an error decoding
$errno = json_last_error();
$err_msg = json_last_error_msg();
die("Json decode failed: Error #$errno: $err_msg");
endif;
//we get here if json_decode succeeded. To get "SP", do...
$stateID = $json_o->addressList->addresses[0]->state->id;
Try:
$json_o = json_decode($string, true);
$estado = $json_o['addressList']['addresses'][0]['state']['id'];
I have the following JSON
[
{
"part_number": {
"id": "1",
"text": "962-00031-17A004"
},
"categoria": null,
"codigo_cti": "",
"fabricante": null,
"modelo": null,
"numero_serie": "",
"obs": ""
}
]
And I use the code bellow to collect data from it. If I select to extract obs, it works fine. I would like to know how can I collect the text and ID from part_number.
$produtos = json_decode($_POST['produtos'], true);
foreach($produtos as $produto){
echo $produto["obs"]; //WORKS FINE
echo $produto["part_number"]["text"]; //DOES NOT WORK
}
Turn it into an object and not array first - its easier and Object Orientated is the way to go.
Here is a working example;
$json = '[
{
"part_number": {
"id": "1",
"text": "962-00031-17A004"
},
"categoria": null,
"codigo_cti": "",
"fabricante": null,
"modelo": null,
"numero_serie": "",
"obs": ""
}
]';
$produtos = json_decode($json, false);
foreach($produtos as $produto){
echo $produto->part_number->id;
}
