How to extract and access data from JSON with PHP?

I unfortunately got some problems getting the exact information I want out of this json file.
Thats a part of the json file:
{
"weather":[
{
"id":600,
"main":"Snow",
"description":"light snow",
"icon":"13n"
}
],
"base":"stations",
"main":{
"temp":271.15,
"feels_like":266.48,
"temp_min":271.15,
"temp_max":271.15,
"pressure":1020,
"humidity":86
}
}
Thats my code to read the informations:
$weather = file_get_contents("weather.json");
$weather = json_decode($weather);
foreach($weather->main as $main) { //<-- This dosen't works
echo $main->temp;
}
foreach($weather->weather as $w) { //<-- This works
echo $w->description;
}
I see that there is a different between the weather- and the main-part with the "[...]" but I don't know how to handle that. Thank you for everyone who helps! :)
foreach($weather->weather as $w) {
echo $w->description;
}
As per Json weather works because it has array of objects so by looping it by foreach you get an object and can access properties there
foreach($weather->main as $main) {
echo $main->temp;
}
Where main is object not array of object so while looping it not showing desired results
Though you can access its value as
$weather->main->temp
Please look to the main and make it like
$array[‘weather’][‘main’][]= main object here
That should work

Here's the json
{"msg":"OK","server_time":"2021-11-19 16:41:22","status":200,"result":{"total_pages":1,"files":[{"download_url":"DOWNLOADLINKHERE1","single_img":"IMAGEURLHERE1","file_code":"CODEHERE1","title":"TITLEHERE1"},{"download_url":"DOWNLOADLINKHERE2","single_img":"IMAGEURLHERE2","file_code":"CODEHERE2","title":"TITLEHERE2"}],"results_total":"2","results":2}}
Here's my code
$json = json_decode($data);
foreach($json["result"] as $result){
foreach($result["files"] as $file){
echo $file["file_code"];
}
}
I want to extract all values from the "file_code". I got an error
Warning: Invalid argument supplied for foreach()
I was able get the VALUE of the first one using
echo $json->result->files[0]->file_code;
Is it possible to use a LOOP for the files[0]?
This line:
foreach($json["result"] as $result){
sees $json['result'] as an object, and so the next line tests for total_pages["files"], which doesn't exist.
Putting both foreach's together solves the problem:
$data='{"msg":"OK","server_time":"2021-11-19 16:41:22","status":200,"result":{"total_pages":1,"files":[{"download_url":"DOWNLOADLINKHERE1","single_img":"IMAGEURLHERE1","file_code":"CODEHERE1","title":"TITLEHERE1"},{"download_url":"DOWNLOADLINKHERE2","single_img":"IMAGEURLHERE2","file_code":"CODEHERE2","title":"TITLEHERE2"}],"results_total":"2","results":2}}';
$json = json_decode($data, true);
foreach($json["result"]["files"] as $file)
print $file["file_code"];
Teh playground
Alternatively, make the JSON result into an array, and use object property accessors instead of associative array bindings.
$data='{"msg":"OK","server_time":"2021-11-19 16:41:22","status":200,"result":[{"total_pages":1,"files":[{"download_url":"DOWNLOADLINKHERE1","single_img":"IMAGEURLHERE1","file_code":"CODEHERE1","title":"TITLEHERE1"},{"download_url":"DOWNLOADLINKHERE2","single_img":"IMAGEURLHERE2","file_code":"CODEHERE2","title":"TITLEHERE2"}],"results_total":"2","results":2}]}';
$json = json_decode($data);
foreach($json->result as $result){
foreach($result->files as $file){
echo $file->file_code;
}
}
Teh playground
I replicated your situation and it turns out that your JSON is invalid. You're missing a } at the end.
The reason for not getting an exception is because json_decode does not throw an error by default. You can make it do so by adding the JSON_THROW_ON_ERROR flag,
read the docs for more info.
This works perfect for me. If you have any thoughts please feel free to correct me.
$num = count($json->result->files);
echo $num;
for($i=0;$i<$num;$i++)
{
echo $json->result->files[$i]->file_code;
}

Hi I'm currently trying to do an API request. The API sends out a json request like this:
[
{
"name": "Test 1"
"yes-or-no": "yes"
},
{
"name": "Test 2"
"yes-or-no": "no"
}
]
My question is, how do I select one of the yes-or-no to echo in the website? I tried doing this:
<?php
$status = json_decode(file_get_contents('url to the json file'));
// Display message AKA uptime.
foreach ($status->yes-or-no as $answer) {
echo $answer.'<br />';
}
?>
But didn't work.
I'm sorry if I got some terms wrong, since I'm pretty new to coding APIs like this.
EDIT: Please see the answer below. It works but now my question is: How do I only display one of them? Instead of both of them displaying at the same time.
I'm not really sure what you are trying to do, but maybe i can shed some light into the question:
$status = json_decode(file_get_contents('url to the json file'), true);
Add ", true" this will make your $status an array instead of an object.
foreach ($status as $answer) {
echo $answer['yes-or-no'].'<br />'; //output yes or no
echo $answer['name'].'<br />'; //output test 1 or test 2
}
Try something like this:
<?php
$statuses = json_decode(file_get_contents('url to the json file'));
foreach ($statuses as $status) {
echo $status->{'yes-or-no'};
}
?>

How to create a JSON object

I have the following PHP code, which gets executed when I hit the Submit button in a form:
// Save data
if(isset($_POST['save'])){
$newDataArr = array();
foreach ($data_array[0] as $k=>$v){
$newDataArr[] = array($k => $_POST[$k]);
}// ./ foreach
echo json_encode($newDataArr);
}
The echo I get is the following:
[{"ID->id":"esKZSCDfIC"},{"DT->createdAt":"2020-01-26T13:02:42"},{"DT->updatedAt":"2020-01-26T13:02:42"},{"ST->aString":"hey1"},{"NU->number":123},{"GPS->coords":["2.2222","44.4444"]},{"BL->aBool":false},{"AR->theArray":["xx","ww"]},{"FL->theFile":"https:\/\/xscoder.com\/xserver\/uploads\/6dydDtoTt5JjZzFc5L5V_image.jpg"},{"PO->userPointer":"vbN3b0C7bC"}]
Then I'll have to add that array into my JSON file as it follows:
$data = json_encode(array_values($newDataArr), JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
file_put_contents('Test.json', $data);
But of course the syntax of my $newDataArr is not the right one, each JSON object must not be inside the { }, so this:
{"ID->id":"esKZSCDfIC"},
must become:
"ID->id":"esKZSCDfIC",
Is there a way to dynamically create a valid JSON array and push it to my Test.json file?
I've been through many posts on StackOverflow, but the result I get is always the same. I must use the PHP code above to get keys and values from my HTML inputs.
Instead of creating and pushing a new array on each iteration, set the values this way:
$newDataArr[$k] = $_POST[$k];
Hope this helps.

I cannot access the contents within the orders array. I am currently doing this to no avail, and am wondering what I am doing wrong:
the $json object is a json response from a rest api.
$orderData = $json['orders'];
foreach($orderData['orders'] as $order){
}
{
"errors":[
],
"orders":[
{
"note":"",
"estimated_shipping_fee":"0.00",
"payment_method":"PAY_CYBERSOURCE",
"escrow_amount":"12.95",
"message_to_seller":"",
"shipping_carrier":"Singpost - Normal Mail",
"currency":"SGD",
"create_time":1532064559,
"pay_time":1532064618,
"recipient_address":{
"town":"",
"city":"",
"name":"Teo",
"district":"",
"country":"SG",
"zipcode":"41253",
"full_address":"In some street somewhjere",
"phone":"23154991",
"state":""
},
"days_to_ship":3,
"tracking_no":"",
"order_status":"SHIPPED",
"note_update_time":0,
"update_time":1532082525,
"goods_to_declare":false,
"total_amount":"12.95",
"service_code":"",
"country":"SG",
"actual_shipping_cost":"",
"cod":false,
"items":[
{
"weight":1.0,
"item_name":"ABC",
"is_wholesale":false,
"item_sku":"5123433123",
"variation_discounted_price":"12.95",
"variation_id":0,
"variation_name":"",
"item_id":1126534500,
"variation_quantity_purchased":1,
"variation_sku":"",
"variation_original_price":"12.95"
}
],
"ordersn":"3589290984539"
}
]
}
Trying to access the variables directly, by say json['orders'][0]['payment_method'] is not working.
convert it to array from json using json_decode(); then you can easily access it and if you want to access using jquery then just convert it object using jQuery.parseJSON();
just use json_decode for retrieving the object and then $obj->note or you can turn it into an array: $array = get_object_vars($obj); like in this answer .

So I've been stumped and I'm not sure how I would continue this
as an example let's just use books.com as the URL and let's say the JSON response from the URL is
[{"title":"first_title","description":"second_title"},
{"title":"second_title","description":"second_description"}]
How would I print all of the titles (just the titles) without knowing exactly how many there are.
I know that I would need to loop through the JSON but I'm unsure how, if I could have any guidance that would be fantastic.
You should get more familiar with json_decode() and foreach().
First you need to decode json (into array in this example) and then iterate through all elements.
Example of working code:
<?php
$json = '[{"title":"first_title","description":"second_title"},
{"title":"second_title","description":"second_description"}]';
$jsonArray = json_decode($json,true);
foreach($jsonArray as $entry) {
echo $entry['title'].'<br>';
}
Output:
first_title
second_title
This key is to actually convert the JSON response into a PHP associative array by using json_decode and then loop through it.
// Convert the JSON into a PHP associative Array
$response = json_decode($curlResponse,true);
// Loop through the array
foreach ($response as $value) {
echo $value['title'];
echo '<br/>';
}
