Access an index of multi-dimensional object in depth [duplicate] - php

Question

This question already has answers here:
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
