How to extract and access data from JSON with PHP?
(1 answer)
Closed 5 years ago.
i'm using Microsoft Emotion Api and it return a result as a json. so i want to access emotion values and assign that values to php variables. i used json_decode function but it can't do it.
result like below
[
{
"faceRectangle": {
"left": 63,
"top": 94,
"width": 66,
"height": 97
},
"scores": {
"anger": 0.00300731952,
"contempt": 2.18678448E-08,
"disgust": 9.284124E-06,
"fear": 0.0001912825,
"happiness": 0.9874571,
"neutral": 0.0009631537,
"sadness": 1.887755E-05,
"surprise": 0.008223598
}
}
]
You need to use this if you want it as an array
$array = json_decode($var, true);
Otherwise it will return the json as a object instead of an array
Doing this should let you access it like so:
$fl = $array[0]['faceRectangle']['left'];

So, I'm new to php and while testing some services, I have a JSON object:
{
"entry": [
{
"authorId": "#me",
"type": "USER"
},
{
"authorId": "514",
"type": "USER"
},
{
"authorId": "516",
"type": "USER"
}
],
"count": 3,
"totalResults": 3
}
and I need to assert that '#me' is part of this object. I tried something like:
$Obj->assertTrue(array_key_exists('#me', $response['entry']));
but it won't just work. Can someone give me a hint regarding this? Thank you
EDIT:
'#me' can be anywhere in the array, not on the first position and I'm asking this for a a test in codecept, so I need to an assert directly
You can loop through your result set to check it for each entry.
function checkEntries($object, $search) {
$object = json_decode($object, true);
foreach($object['entry'] as $entry) {
if ($entry['authorId'] == $search) {
return true;
}
}
return false;
}
Or you can use this:

How can I get useful error messages in PHP?
(41 answers)
Closed 3 years ago.
I have a json that I need to filter a specific key and value from
the following json
{
"5": {
"Owner": "94EAC",
"Record":"0121ln"
},
"15": {
"Owner": "009AC",
"Record":"0120Pc"
},
"1": {
"Owner": "00G11A",
"Record":"000lPcn"
},
"199": {
"Owner": "00G1y9",
"Record":"01211cn"
},
"33": {
"Owner": "001AC",
"Record":"0121n"
}
}
I would like to be able to pass the first int and get back array for that number.
For example if I pass 15 I get
{
"Owner": "009AC",
"Record":"0120Pc"
}
I tried foreach loop but cannot set specific value for the first int
If I assign $data = json
then $date[15] didn't work
$data->15 also didn't work
I did also use the json decode and was able to print an array but wasn't able to get a single value
Any help would be great, I did spend all day and still cannot get an answer.
Thank you
Using Array:
$arr = json_decode($json, true);
print_r( $arr['15']);
Using Object:
$obj = json_decode($json);
print_r( $obj['15']);

How to loop through PHP object with dynamic keys [duplicate]

Closed 3 years ago.
The following chunk of data is produced by a webpage along with other html data;
"search":{"searchResults":{"results":[
{"id":"123","name":"ABC","rating":{"average":0,"count":2,"__typename":"Rating"},"category":"AAA/Cars","__typename":"ProductQuery"},
{"id":"456","name":"DEF","rating":{"average":5,"count":8,"__typename":"Rating"},"category":"BBB/Bikes","__typename":"ProductQuery"}
{"id": //and so on//
"}
]}}
How to extract multiple variables from this string like data like "id", "rating" etc., to be able to print it on another php page?
You can use json_decode to convert JSON to the array and then iterate through the array
$json = '{
"search":
{
"searchResults":
{
"results":[
{"id":"123","name":"ABC","rating":{"average":0,"count":2,"__typename":"Rating"},"category":"AAA/Cars","__typename":"ProductQuery"},
{"id":"456","name":"DEF","rating":{"average":5,"count":8,"__typename":"Rating"},"category":"BBB/Bikes","__typename":"ProductQuery"}
]
}
}
}';
$jsonToArray = json_decode($json,true);
foreach($jsonToArray['search']['searchResults']['results'] as $v){
echo $v['id'];
print_r($v['rating']);echo '<br/>';
}

How can I access a deep object property named as a variable (dot notation) in php?
(5 answers)
Closed 4 years ago.
I have a .json configuration file. Using PHP, I'm trying to get its contents as an object by json_decode() and validate it. The JSON file contains multi-dimensional data. The problem is with accessing a member in depth dynamically.
For instance, consider the following data:
{
"somebody": {
"name": "Ali",
"age": 13,
"life": {
"stat": "good",
"happy": true
}
}
How to access the value of the following dynamically?
$happy = $data->somebody->life->happy;
What I mean from a dynamic access is something like this:
$happyIndex = "somebody->life->happy";
$happy = $data->{$happyIndex};
Also, I don't want to use eval().
Thanks.
Assuming you have a JSON data return
data="{
"somebody": {
"name": "Ali",
"age": 13,
"life": {
"stat": "good",
"happy": true
}
}"
data = jQuery.parseJSON(data);
then you can navigate to different parts of data by navigating
var name= data.somebody[0].name;
var age= data.somebody[0].age;
You will need a $.each function if you have more than one data in "somebody" array.
PHP Version:
$data='{"somebody":{"name": "Ali","age": "13","life": {"stat": "good","happy": "true"} }}';
$data = json_decode($data,TRUE);
$name= $data['somebody']['name'];
$age= $data['somebody']['age'];
echo("<pre>");
echo($name);
echo($age);
echo("</pre>");
//OUTPUT RESULT Ali 13

I am unable to get values of array of this json... how can i have all these values seperately!!
{
"id": "jai",
"pwd": "123",
"user": [
{
"fname": "jai",
"lname": "gupta"
},
{
"fname": "sameer",
"lname": "seth"
}
],
"college": "vit"
}
$myArray = json_decode($json, true);
var_dump($myArray['id']);
var_dump($myArray['user'][0]['fname']);
You can decode these values from json to object.
$result = json_decode('{"id":"jai","pwd":"123","user":[{"fname":"jai","lname":"gupta"},{"fname":"sameer","lname":"seth"}],"college":"vit"}');
and acccess like below:
$result->id;
$result->pwd;
You can access each "value" by accessing regular php array key value pairs.
$jsonn = '{"id":"jai","pwd":"123","user":[{"fname":"jai","lname":"gupta"},{"fname":"sameer","lname":"seth"}],"college":"vit"}';
$new = json_decode($jsonn, true);
$id = $new['id'];
$user = $new['user'];
..... and so on.
Hope this helps.
Cheers!
