Here is my JSON data :
{
"Liste_des_produits1": [{
"Added_Time": "28-Sep-2009 16:35:03",
"prod_ingredient": "sgsdgds",
"prod_danger": ["sans danger pour xyz"],
"prod_odeur": ["Orange"],
"prod_nom": "ceciestunproduit",
"prod_certification": ["HE • Haute Efficité", "Certifier Ecologo", "Contenant recyclable"],
"prod_photo": "",
"prod_categorie": ["Corporel"],
"prod_desc": "gdsg",
"prod_format": ["10 kg", "20 kg"]
}, {
"Added_Time": "28-Sep-2009 16:34:52",
"prod_ingredient": "dsgdsgdsf",
"prod_danger": ["Sans danger pour le fausse sceptiques"],
"prod_odeur": ["Agrumes", "Canneberge"],
"prod_nom": "jsute un test",
"prod_certification": ["100% Éco-technologie", "Certifier Ecologo", "Contenant recyclable"],
"prod_photo": "",
"prod_categorie": ["Corporel"],
"prod_desc": "gsdgsdgsdg",
"prod_format": ["1 Litre", "10 kg"]
}]
}
In PHP, what is the way to access different values of data?
Like: prod_ingredient or prod_danger.
I have tried:
$prod = $result->{'Liste_des_produits1'};
print_r($prod[0]); // error
and
$result = json_decode($json);
print_r($result['Liste_des_produits1'].prod_ingredient[1]); // error
Use json_decode to convert the data to an associative array.
$data = json_decode($jsonString, true);
// extend this concept to access other values
$prod_ingredient = $prod['Liste_des_produits1'][0]['prod_ingredient'];
Use json_decode
Then you can access the data as a regular array.

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
I am using the following API: https://openweathermap.org and it gives a JSON response to get the current weather.
{
"coord":{
"lon":
"lat":
},
"weather":[
{
"id":521,
"main":"Rain",
"description":"shower rain",
"icon":"09n"
}
],
"base":"stations",
"main":{
"temp":289.22,
"pressure":1004,
"humidity":82,
"temp_min":288.15,
"temp_max":290.15
},
"visibility":10000,
"wind":{
"speed":4.1,
"deg":210
},
"clouds":{
"all":100
},
"dt":1501793400,
"sys":{
"type":1,
"id":5060,
"message":0.0039,
"country":"GB",
"sunrise":1501734589,
"sunset":1501790444
},
"id":3333126,
"name":"Borough of Blackburn with Darwen",
"cod":200
}
What is the correct way to go about getting the main and description in the JSON?
I have attempted the code below but it doesn't work:
$url = "http://api.openweathermap.org/data/2.5/weather?lat=" . $latitude . "&lon=" . $longitude . "&APPID=71f4ecbff00aaf4d61d438269b847f11";
$dirty_data = file_get_contents( $url );
$data = json_decode( $dirty_data );
echo $data['weather']['main'];
When using json_decode() to convert json data to php type, it will always convert it into an object. To be clear you can access weather's main and description property like this:
echo $data->weather[0]->main // outputs main
echo $data->weather[0]->description // outputs description
Update:
Besides you can also convert data into an associative array by passing bool(true) $assoc argument to the json_decode() function.
$data = json_decode( $dirty_data, true );
And extract your data like this:
echo $data['weather'][0]['main']; // for main
echo $data['weather'][0]['description']; // for description
Yo can always do var_dump($data) to see what you have and how to access it.
json_decode returns a stdClass not an array.
$data->weather[0]->main;
Should be the right thing.
{} symbolizes an object and [] symbolizes an array. Notice weather:[{...}] which means weather is an array of objects.
Try
$data = json_decode( $dirty data, true)
It doesn't convert to an object if you supply the true argument.
I have JSON Object which I have encoded like so
{
"id": "",
"steps": [
{
"target": "purchase_order_items_itemmaster_id",
"title": "",
"placement": "",
"content": "",
"xoffset": "",
"yoffset": ""
}
]
}
$JSONData = json_encode($finalData,JSON_PRETTY_PRINT);
I am taking this JSON data and storing it in a file like so
File::put("path","var tour = \n [ \n\t $JSONData \n ];");
which looks something like this in the file
var tour =
[
{
"id": "",
"steps": [
{
"target": "purchase_order_items_itemmaster_id",
"title": "",
"placement": "",
"content": "",
"xoffset": "",
"yoffset": ""
}
]
}
];
Now I am reading it back form the second line like so
[
{
"id": "",
"steps": [
{
"target": "purchase_order_items_itemmaster_id",
"title": "",
"placement": "",
"content": "",
"xoffset": "",
"yoffset": ""
}
]
}
];
The problem is when I want to decode it back it doesn't happen,this is how I am trying to do that,
$lines = file_get_contents("path",NULL,NULL,10);
$a = json_decode($lines);
Now according to expected output the $a should have the decoded data but it has null.
Can someone point out the mistake?
I believe the issue is the semicolon at the end of the JSON you've read back in from the file. Try chopping that off before attempting json_decode:
$a = json_decode(rtrim($lines, ";"));
pass the second parameter true for recursively decoding
$a = json_decode(chop($lines,";"),true);
check the php mannual here json_decode
It will be
$str = file_get_contents('http://example.com/example.json/');
$json = json_decode($str, true); // decode the JSON into an associative array
See the post
Parsing JSON file with PHP
try to save data in file like
$fp = fopen('path', 'w');
fwrite($fp, json_encode($JSONData)); //if $JSONData is in string
fclose($fp);
instead of
File::put("path","var tour = \n [ \n\t $JSONData \n ];");
//and read like
// Read JSON file
$json = file_get_contents('path');
//Decode JSON
$json_data = json_decode($json,true);
//Print data
print_r($json_data);
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.
I tried to request the weather from a web service supplying data in JSON format. My PHP request code, which did not succeed was:
$url="http://www.worldweatheronline.com/feed/weather.ashx?q=schruns,austria&format=json&num_of_days=5&key=8f2d1ea151085304102710";
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
echo $data[0]->weather->weatherIconUrl[0]->value;
This is some of the data that was returned. Some of the details have been truncated for brevity, but object integrity is retained:
{ "data":
{ "current_condition":
[ { "cloudcover": "31",
... } ],
"request":
[ { "query": "Schruns, Austria",
"type": "City" } ],
"weather":
[ { "date": "2010-10-27",
"precipMM": "0.0",
"tempMaxC": "3",
"tempMaxF": "38",
"tempMinC": "-13",
"tempMinF": "9",
"weatherCode": "113",
"weatherDesc": [ {"value": "Sunny" } ],
"weatherIconUrl": [ {"value": "http:\/\/www.worldweatheronline.com\/images\/wsymbols01_png_64\/wsymbol_0001_sunny.png" } ],
"winddir16Point": "N",
"winddirDegree": "356",
"winddirection": "N",
"windspeedKmph": "5",
"windspeedMiles": "3" },
{ "date": "2010-10-28",
... },
... ]
}
}
}
This appears to work:
$url = 'http://www.worldweatheronline.com/feed/weather.ashx?q=schruns,austria&format=json&num_of_days=5&key=8f2d1ea151085304102710%22';
$content = file_get_contents($url);
$json = json_decode($content, true);
foreach($json['data']['weather'] as $item) {
print $item['date'];
print ' - ';
print $item['weatherDesc'][0]['value'];
print ' - ';
print '<img src="' . $item['weatherIconUrl'][0]['value'] . '" border="0" alt="" />';
print '<br>';
}
If you set the second parameter of json_decode to true, you get an array, so you cant use the -> syntax. I would also suggest you install the JSONview Firefox extension, so you can view generated json documents in a nice formatted tree view similiar to how Firefox displays XML structures. This makes things a lot easier.
If you use the following instead:
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
The TRUE returns an array instead of an object.
Try this example
$json = '{"foo-bar": 12345}';
$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345
http://php.net/manual/en/function.json-decode.php
NB - two negatives makes a positive . :)
Seems like you forgot the ["value"] or ->value:
echo $data[0]->weather->weatherIconUrl[0]->value;
When you json decode , force it to return an array instead of object.
$data = json_decode($json, TRUE); -> // TRUE
This will return an array and you can access the values by giving the keys.
You have to make sure first that your server allow remote connection so that the function file_get_contents($url) works fine , most server disable this feature for security reason.
While editing the code (because mild OCD), I noticed that weather is also a list. You should probably consider something like
echo $data[0]->weather[0]->weatherIconUrl[0]->value;
to make sure you are using the weatherIconUrl for the correct date instance.
