My code:
$json_response = json_decode($response, true);
$tag= $json_response['results']['tags'][0]['tag'];
print $tag;
My JSON:
{
"results": [
{
"tagging_id": null,
"image": "image.jpg",
"tags": [
{
"confidence": 100,
"tag": "herb"
},
{
"confidence": 98.3637619018555,
"tag": "plant"
}
]
}
]
}
I am trying to output "herb". I have looked up through examples but cannot figure out where the bug is.
I am reading results and then the trees.
You have to fetch the first element inside ['results'].
echo $json_response['results'][0]['tags'][0]['tag'];

I have multiple JSON files with different structures. What I want to do is to automatically display these JSON outputs with HTML.
Some of my JSON outputs are as follows: (Think of each of these as separate files and need to be processed separately)
{
"parts": [
{
"#attributes": {
"id": "part1"
},
"car": "Peugeot",
"service": 5,
"location": 2996,
"price": "44.95",
"date": "2000-10-01"
},
... other objects
]
}
{
"licenses":[
{
"driver":"John",
"year":26,
"info":null
},
... other objects
]
}
Now, to process these files, I send the page name with GET on PHP and I want the corresponding JSON output to be printed to the screen with HTML as <span>$key</span> -> <span>$value</span>
How can I make this dynamic JSON output read event with PHP? Do I need to create a recursive function?
Because the files have different structures from each other. I hope I was able to explain my problem. Thanks already for yours help.
I suggest the following:
get required JSON file name from GET or POST, for example:
$jsonfilename = $_GET['file'];
The above does not include any security protection! this is a separate topic,
so do some research.
load your json file and parse it:
$json = file_get_contents('/path/'.$jsonfilename);
$data = json_decode($json, true);
read your json data:
foreach ($data as $key=>$value){
echo ''.$key.' -> '.$value.'';
}
A simple example for your PARTS file:
$json = '
{
"parts":
[
{
"#attributes": {
"id": "part1"
},
"car": "Peugeot",
"service": 5,
"location": 2996,
"price": "44.95",
"date": "2000-10-01"
},
{
"#attributes": {
"id": "part2"
},
"car": "Renault",
"service": 8,
"location": 3100,
"price": "99.95",
"date": "2022-03-01"
}
]
}';
$arr = json_decode($json, true);
foreach($arr["parts"] as $part) {
foreach($part as $k => $v){
if($k == "#attributes")
echo "<h1>" . $v["id"] ."</h1>";
else
echo "<span>$k</span> -> <span>$v</span> <br/>";
}
}
This produces:
I have this json code
"result": [
{
"update_id": 74783732,
"message": {
"message_id": 852,
"from": {
"id": ---,
"is_bot": false,
"first_name": "---",
"username": "---",
"language_code": "en"
},
"chat": {
"id": ---,
"first_name": "---",
"username": "---",
"type": "private"
},
"date": 1646306224,
"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 have web page which get Json responce like this
{
'hotel_1page':[
{
'id':'10',
'name':'fsf',
'telephone':'233333'
},
{
'id':'11',
'name':'setttttt',
'telephone':'213123123'
},
{
'id':'12',
'name':'fsdfsdf',
'telephone':'122212121'
},
{
'id':'13',
'name':'xxcvcxv',
'telephone':'2147483647'
},
{
'id':'14',
'name':'dssdfg',
'telephone':'2147483647'
},
{
'id':'15',
'name':'dfsdfsdf',
'telephone':'21312321'
},
{
'id':'16',
'name':'fx_test_nw1',
'telephone':'23232323'
},
{
'id':'17',
'name':'fx_test_nw2',
'telephone':'31313131'
}
]
}
and i want to loop through this data and get this data to array and display as html how can i achieve this
this is where i get get json responce,and when i var_dump json encoded variable it says null,where $json variable shows the json responce,
$json = file_get_contents('http://www.example.com/hotel_list.php');
var_dump($json);
$array = json_decode($json, true);
var_dump($array);
The json that you are trying to parse is invalid. Change the single quotes to double quotes and you should be able to parse it to an array.
The JSON documentation says
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.
This should work:
$json = '{ "hotel_1page": [ { "id": "10", "name": "fsf", "telephone": "233333" }, { "id": "11", "name": "setttttt", "telephone": "213123123" }, { "id": "12", "name": "fsdfsdf", "telephone": "122212121" }, { "id": "13", "name": "xxcvcxv", "telephone": "2147483647" }, { "id": "14", "name": "dssdfg", "telephone": "2147483647" }, { "id": "15", "name": "dfsdfsdf", "telephone": "21312321" }, { "id": "16", "name": "fx_test_nw1", "telephone": "23232323" }, { "id": "17", "name": "fx_test_nw2", "telephone": "31313131" } ] }';
echo '<pre>';
var_dump(json_decode($json, true));
echo '</pre>';
I replaced all single quotes with double quotes, that did the trick.
I used single quotes before which caused json_decode to return null
[Edit for usage]
To use the data, you could use something like this:
$obj = json_decode($json, true);
foreach($obj as $row)
{
foreach($row as $key => $item)
{
// $item['id']
// $item['name']
// $item['telephone']
}
}
I'm using a nested foreach() because the id, name and telephone are an array within the hotel_page1 array
I have a TXT file containing some facebook Open Graph info like this:
{
"data": [
{
"name": "Avatar",
"category": "Movie",
"id": "82771544063",
"created_time": "2012-04-13T21:16:56+0000"
},
{
"name": "HappyDance",
"category": "Movie",
"id": "243564344063",
"created_time": "2012-04-13T21:16:56+0000"
}
],
"paging": {
"next": "https://graph.facebook.com/me/likes?format=json&limit=5000&offset=5000&__after_id=5546653546361"
}
}
In PHP, I want to extract all the id numbers from the rows that show
"id": "XXXXXXXXXXXX",
The output should look like this:
I like 8277564344063
I like 243564344063
I started the following but I am getting an error:
<?php
$file_handle = fopen("raw.txt", "rb");
ob_start();
$text = file_get_contents('raw.txt');
$decode = json_decode($text);
print_r($decode);
$new_content = ob_get_clean();
file_put_contents("likes.txt", $new_content);
fclose($file_handle);
?>
The error is that my output is blank! What am I doing wrong?
Please help?
You don't have valid JSON.
The JSON Object below this line is valid JSON. I removed the comma after your last associative array within your "data" array. You shouldn't need a comma at the end of the array.
{
"data": [
{
"name": "Avatar",
"category": "Movie",
"id": "82771544063",
"created_time": "2012-04-13T21:16:56+0000"
},
{
"name": "HappyDance",
"category": "Movie",
"id": "243564344063",
"created_time": "2012-04-13T21:16:56+0000"
}
],
"paging": {
"next": "https://graph.facebook.com/me/likes? format=json&limit=5000&offset=5000&__after_id=5546653546361"
}
}
Parse error on line 14:
... }, ], "paging": {
---------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
As I removed the comma from the non-valid JSON. I was able to get the result you wanted.
<?php
$json_object = file_get_contents('fb.json');
if(!$json_object) {
echo "oops, cant read the file";
}
// remap json_object
$json_object = json_decode($json_object,true);
foreach($json_object['data'] as $item) {
$items[] = "I like" . ' ' . $item['id'];
/* If you want to just echo " I like xyz" etc
* use echo "I like" . $item['id'];
*/
}
$list = implode(',',$items);
echo $list;
?>
