{
"Group": [
{
"name": "HolderOne",
"operators": [
{
"username": "ken",
"status": 3
},
.....etc.....
The JSON feed I am attempting to manipulate has to format above.
I wish to be able to display username and status.
$json = file_get_contents("urlhere");
$obj=json_decode($json);
echo $obj->username;
echo $obj->status;
This obviously doesn't work as they are nested(?) within the feed...I have tried:
$obj->Group[0]->name->operators->username
and
$obj->Group[0]->name->username
to no avail (as well as json_decode with ,true and ['name'], etc).
Am I being particularly dim?
when I do a var dump, the data is being collected from the feed okay.
The best way to figure this out is to iteratively do print_r's:
print_r($obj)
//prints what you see above
print_r($obj['Group']
//prints the Group Object
print_r($obj['Group'][0])
//prints first element in Group Object
print_r($obj['Group'][0]['operators'])
//etc.....
That's how I find out how to access these deep elements if I get a little stuck. Though it appears to me that you want:
$obj->Group[0]->operators[0]->username

i'm trying to get the fields "name, price, image and rarity" to show in a php file, anyone can help me? Thanks ;D
{
"status": 300,
"data": {
"date": "2019-09-16T00:00:00.000Z",
"featured": [
{
"name": "Flying Saucer",
"price": "1,200",
"images": {
"icon": icon.png",
},
"rarity": "epic",
},
I'm using this that a friend told me, but i cant put that to work :c
<?php
$response = json_decode(file_get_contents('lista.json'), true);
foreach ($response as $val) {
$item = $val['name'];
echo "<b>$item</b>";
}
?>
I'm not quite sure what you are trying to achieve. You can just access the contents via the $response array like this:
echo $response['status']; // would output 300
You can use foreach to iterate through the array. For example: If you want to output the name of every element of the array you can use:
foreach ($response['data'] as $val) { // loop through every element of the data-array (if this makes sense depends on the structure of the json file, cant tell because it's not complete)
echo $val['featured']['name'];
}
You gotta get the index in $val['data']['featured']['name'] to retrieve the name index.
When you defined the second parameter of json_decode, you said that you want your json to be parsed to an array. The brackets in the original json identify when a new index of your parsed array will begin.
I suggest you to read about json_decode and json in general:
JSON: https://www.json.org/
json_decode function: https://www.php.net/manual/en/function.json-decode.php
In my database I have POSTed following JSON with REST API:
{
"author": "Someone",
"hero_name": "Iron Man",
"hero_desc": ["Iron", "Man"],
}
Now in database Table, the entry says only Array for the hero_desc.
I cannot figure out how to get the actual items in that array.. for example to fetch Iron from hero_desc.
Here is how it gets returned with GET request:
{
"id": "11",
"user_id": "1",
"author": "Someone",
"hero_name": "Iron Man",
"hero_desc": "Array",
}
I am quite new to PHP so I am worried that I would need to mess up my whole app architecture to get this to work. I though PHP can handle fetching arrays by default if it sees it's an JSON Array.
use json_decode(); function for change json to array
$json_to_array = json_decode($your_json_variable_name);
You could change array data to JSON with json_encode In one hand you have an array without the key that code makes a number key for that in another hand if have an array with the key you can get that inside JSON with that key.
$content ='your content or your array data';
header('Content-Type: application/json; charset=utf8');
echo json_encode($content);
I know this is a basic question, but I cannot figure out how to actually do this. I have read countless tutorials about it but they seemingly do not work.
var_dump($google_check);
returns the following:
string(488) "{
"matches": [
{
"threatType": "MALWARE",
"platformType": "LINUX",
"threat": {
"url": "http://malware.testing.google.test/testing/malware/"
},
"cacheDuration": "300s",
"threatEntryType": "URL"
},
{
"threatType": "MALWARE",
"platformType": "LINUX",
"threat": {
"url": "http://malware.testing.google.test/testing/malware/"
},
"cacheDuration": "300s",
"threatEntryType": "URL"
}
]
}
"
I want to echo results from the array, so something like
echo $google_check[0][matches][threat];
echo $google_check[1][matches][threat];
Problem is this returns illegal offset on matches and threat, and only echo's a single character {
What am I doing wrong? How do I echo the results from this array without dumping the entire array?
The response you recieved is in json so you'll need to first json_decode the response.
$decoded = json_decode($google_check, true);
Then you can access it like an array
echo $decoded['matches'][0]['threat'];
echo $decoded['matches'][1]['threat'];
if you want the url value you'll need to do it like this.
echo $decoded['matches'][0]['threat']['url'];
echo $decoded['matches'][1]['threat']['url'];
please also note, when looking at array keys that aren't numerical you'll need to wrap in quotes (e.g. $decoded['matches'] instead of $decoded[matches]).
Here's a quick explanation on json
https://www.tutorialspoint.com/json/json_php_example.htm
I'm trying to get specific data from a JSON file (url) and save that data in a PHP variable.
The JSON comes from an url. For example:
https://euw.api.pvp.net/api/lol/euw/v1.4/summoner/by-name/Viducius?api_key=secret
The JSON file:
{
"viducius": {
"id": 26541044,
"name": "Viducius",
"profileIconId": 591,
"revisionDate": 1480517139000,
"summonerLevel": 30
}
}
So my question is how can I get the data from id, in this case 26541044, and put that into a PHP variable?
Also to get the data from the JSON file, I have to search for the id while the array name 'viducius' came from a PHP variable.
TLDR:
The array $arrayName contains an id '26541044' that has to be saved into variable $id
Is there someone who can help me with this? I was thinking on doing this in jQuery but if it's easier with PHP only thats fine too.
That is a JSON String, therefore you need to convert it into a PHP data structure. PHP Provides json_decode() to do that.
$json_string = '{"viducius": {
"id": 26541044,
"name": "Viducius",
"profileIconId": 591,
"revisionDate": 1480517139000,
"summonerLevel": 30
}
}';
$obj = json_decode($json_string);
$id = $obj->viducius->id;
echo 'id = ' . $id;
I'm trying to pull the price from the following JSON but can't seem to figure out how to reference the actual values:
{"cards": [ { "high": "0.73", "volume": 1, "percent_change": "-2.67", "name": "Lightning Bolt", "url": "http://blacklotusproject.com/cards/Revised+Edition/Lightning+Bolt/", "price": "0.73", "set_code": "3ED", "average": "0.73", "change": "-0.02", "low": "0.73"}], "currency": "USD" }
So far I've got this code, which gets into the cards array but I'm unsure how to get farther - every attempt I've tried returns null.
$json = file_get_contents($url); $data = json_decode($json, TRUE);
echo var_dump($data[cards]);
Can someone shed light on what I need to do?
$data['cards'] has another array within it. You will need to access this array with index 0. For instance, $data['cards'][0]['high'] and so on.
$data['cards'] is an array itself, so you could do:
foreach ($data['cards'] AS $carditem) {
echo $carditem['high'];
...
}
to get all items in that array,
or if you only want the first item $data['cards'][0]['...']
To access using a string literal array index, always use quotes.
$data["cards"]
