I'm trying to extract the value from the event key (delivered) using PHP. I thought the follow would work below but I'm getting no results. I know this is probably a simple thing to do and probably looking too far into it.
How I am trying to extract the value
$status = json_decode($status, true);
echo $status[1]['event'];
Here is my JSON file
{
"events":[
{
"email":"email#gmail.com",
"date":"2020-02-17T22:16:58.000+01:00",
"subject":"PHPMailer SMTP test",
"messageId":"<hdskjfjsdhfsjdkfdksh>",
"event":"delivered",
"tag":"",
"from":"test#gmail.com"
}
]
}
Any help would be appreciated :)
The first issue is that your JSON file is wrong formatted. It should be:
{
"events": [
{
"email": "email#gmail.com",
"date": "2020-02-17T22:16:58.000+01:00",
"subject": "PHPMailer SMTP test",
"messageId": "74483437597589347843758934759",
"event": "delivered",
"tag": "",
"from": "test#gmail.com"
}
]
}
Second, $status[1]['event'] is also wrong. You should use $status['events'].
I figured it out. So I am parsing a json response from CURL...
$response = curl_exec($curl);
I changed this
$status = json_decode($status, true);
echo $status['events'][0]['event'];
to
$status = json_decode($response, true);
echo $status['events'][0]['event'];
I totally missed that mistake. Thanks to everyone who reach out!

I'm trying to put a users "favourite" game into the corresponding file for their user upon post.
if(isset($_POST['favourite'])){
$filetxt = 'data/users.json';
$formdata = $_POST['favourite']; //this contains the value "game"
$arr_data = array();
if(file_exists($filetxt)) {
$jsondata = file_get_contents($filetxt);
$arr_data = json_decode($jsondata, true);
}
$arr_data[][$_SESSION['username']]['favourite'] = $formdata;
$jsondata = json_encode($arr_data, JSON_PRETTY_PRINT);
file_put_contents('data/users.json', $jsondata);
}
The file is structured as:
[
{
"CNR": {
"first-name": "test",
"last-name": "test",
"email": "test",
"country": "test",
"password": "test",
"favourite": []
}
},
{
"usertest": {
"first-name": "test",
"last-name": "test",
"email": "test",
"country": "United States",
"password": "password",
"favourite": []
}
}
]
Currently it will add the correct data however not into the array, but onto the end.
[
{
"CNR": {
"first-name": "test",
"last-name": "test",
"email": "test",
"country": "test",
"password": "test",
"favourite": []
}
},
{
"usertest": {
"first-name": "test",
"last-name": "test",
"email": "test",
"country": "United States",
"password": "password",
"favourite": []
}
},
{
"CNR": {
"favourite": "game"
}
}
]
I've tried things like arraypush, splice and other methods however I'm not sure what is the best for this use case.
Any thoughts/recommendations on how I can best achieve this with the desired result are greatly appreciated, thanks!
$arr_data[$_SESSION['username']]['favourite'][] = $formdata;
Difference is that I moved [] to the end of the $arr_data.
Before adding it to array, you need to check if the key exists and then proceed rather than just adding the code.
if(isset($_POST['favourite'])){
$filetxt = 'data/users.json';
$formdata = $_POST['favourite']; //this contains the value "game"
$arr_data = array();
if(file_exists($filetxt)) {
$jsondata = file_get_contents($filetxt);
$arr_data = json_decode($jsondata, true);
}
// changes over here
if(isset($arr_data[$_SESSION['username']])){
if(isset($arr_data[$_SESSION['username']]['favourite'])){
$arr_data[$_SESSION['username']]['favourite'][] = $formdata;
} else {
$arr_data[$_SESSION['username']]['favourite'] = $formdata;
}
} else {
$arr_data[][$_SESSION['username']]['favourite'] = $formdata;
}
$jsondata = json_encode($arr_data, JSON_PRETTY_PRINT);
file_put_contents('data/users.json', $jsondata);
}
I can see that most have answered the question but might I also provide some suggestions (food for thought) on your process?
1). Firstly, I can't work out if you are storing ALL users in a single file or if there's a file per user. Example username.json
I am going to assume there is a file per username because there should be to make file writes quicker and it would require the main file to be locked for everyone else just because one user is writing to it.
2). I noticed that the favourite part seems to be stored in the _SESSION too. If the _SESSION is storing the same mini array in it (a replica of what is stored in the file) then there's no point in opening the file to write a single value and then save it again. You may as well just write over the existing file straight away. Like this...
$writeToFile = json_encode($_SESSION[mydata]);
$fh = fopen("/path/to/username.json","w+");
fwrite($fh,$writeToFile);
fclose($fh);
// You could also use file_put_contents but most prefer
// to use fopen()
3). I will assume the passwords you are storing are encrypted and nobody can type [yourdomain]/users/username.json to see the raw output of the json files. You might want to ensure .json files aren't accessible from the browser. You can do that with .htaccess.
Problem is in this code, you are creating every time a new sub array:
Change this:
$arr_data[][$_SESSION['username']]['favourite'] = $formdata;
To this
if(isset($arr_data[$_SESSION['username']])) {
$arr_data[$_SESSION['username']]['favourite'] = $formdata;
}
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 trying to parse my JSON response so I can print a specific value. Please help me in the right direction.
I am getting the following response:
{
"services": [{
"id": "9999999",
"domainname": "example.com",
"total": "100.90",
"status": "Active",
"billingcycle": "Monthly",
"date": "2017-11-25",
"category": "mobile phone",
"url": "example.com",
"name": "Iphone"
}]
}
How can I be able to print only the "name" value of this JSON value?
What I tried:
$someData = json_decode($response, TRUE);
// this print the whole response
print_r($someData);
foreach($someData['services'] as $result) {
echo $result['name'], '<br>';
}
But the foreach loop does not print the value which I need from the JSON response. What's wrong with this piece of PHP code?
Update: edited the json the first name was domainname my bad
You have a simple syntax error here
echo $result['name'],'<br>';
Try this
echo $result['name']. '<br>';
with a . dot instead of a comma ,
Otherwise It works fine as you can see here.
http://sandbox.onlinephpfunctions.com/code/9be6789973b0e70772403a786b379749f6db0a7a
I suggest turning error reporting on.
<?php
error_reporting(-1);
ini_set('display_errors', 1);
And you will be able to see most of these issues more clearly.
I am having a lot of issues getting a response from json using php.
The code below echos nothing and I have no idea why.
I need to be able to access all points of that json file individually through functions.
file.json
{
"file":{
"name": "File Name",
"description": "This is a file!",
"license": "glp-2.0",
"version": "1.1.1",
"author": [{
"name": "Author Name",
"email": "name#domain.com"
}],
"require": [{
"php": ">= 5.2.4",
"myslq": ">= 5.0",
}]
}
}
localhost/data.php
define('PATH', 'http://domain.com/json/');
function test(){
$json = file_get_contents( PATH."file.json" );
$data = json_decode($json,true);
echo $data['file']['name'];
}
test();
define('PATH', 'http://domain.com/json/');
function test(){
$json = file_get_contents( PATH."file.json" );
$data = json_decode(preg_replace('/,\s*([\]}])/m', '$1', utf8_encode($json)),true);
echo $data['file']['name'];
}
test();
preg_replace('/,\s*([]}])/m', '$1', utf8_encode($json))
In bold above fixed my issue.
It's a good idea to use a debugger or to do some debug print outs.
Try:
$json = file_get_contents( PATH."file.json" );
var_dump($json);
$data = json_decode($json,true);
var_dump($data)
Now you can see if file_get_contents or json_decode doesn't work.
A much better option is to use a debugger while developing software in order to find failures easily. Get more information on: http://xdebug.org/.
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.
