How can I parse a JSON file with PHP?

Question

I tried to parse a JSON file using PHP. But I am stuck now. This is the content of my JSON file: { "John": { "status":"Wait" }, "Jennifer": { "status":"Active" }, "James": { "status":"Active", "age":56, "count":10, "progress":0.0029857, "bad":0 } } And this is what I have tried so far: <?php $string = file_get_contents("/home/michael/test.json"); $json_a = json_decode($string, true); echo $json_a['John'][status]; echo $json_a['Jennifer'][status]; But because I don't know the names (like `'John'`, `'Jennifer'`) and all available keys and values (like `'age'`, `'count'`) beforehand, I think I need to create some foreach loop. I would appreciate an example for this.

You're really close and you're exactly right, you need to use a foreach loop. Please see the code below for more insight into how to handle this situation:

<?php

$string = file_get_contents("/home/michael/test.json");

$json_a = json_decode($string, true);

foreach($json_a AS $key=>$value){

echo '<br>Name:'.$key;

echo ', Status:'.$value['status'];

if(isset($value['age'])){

echo ', Age:'.$value['age'];

}

if(isset($value['count'])){

echo ', Count:'.$value['count'];

}

if(isset($value['progress'])){

echo ', Progress:'.$value['progress'];

}

if(isset($value['bad'])){

echo ', Bad:'.$value['bad'];

}

}
