Generate dynamic html with JSON output (with php) - php

Question

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.

Answer 1

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.'';
}

Answer 2

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:
