PHP Nested JSON Array reading

Question

I have nested JSON in PHP, I am new to PHP and I am unable to read the below-nested JSON. Here is the long JSON file.

<?php
$nestedjson='{
    "value": [
      {

I would like to read and print the values of "hostPoolType" from the above JSON, I have tried the below code it didn't work.

$arr = json_decode($nestedjson, true);

$hostpooltype = $arr['properties']['hostPoolType'];

//print_r($hostpooltype);

foreach($hostpooltype as $item)
{
    echo $item;
    echo '<br>';
}
?>

It's not returning the correct result. Can anyone please help here?

Shouldn't it be $arr['value'][0]['properties']['hostPoolType']? — frz3993

Yes, you are correct, however, I would like to read the values of the array[1] and [2] as well. I think I need to find the array length and need to run a for loop? — askwizard

So then if you need values from 1-2 as well you need to loop through them. You just can't ignore the one key and expect to it iterate through for you... — Crimin4L

you should run loop for each value key of json array. use this.

<?php
$arr = json_decode($nestedjson, true);
foreach ($arr['value'] as $newArr){
    echo $newArr['properties']['hostPoolType'];
    echo '<br>';
}
?>

I have found the solution here.

$arr = json_decode($nestedjson, true);
$hostpooltype = array();
$names = array();
foreach ($arr['value'] as $newArr)
{

  $hostpooltype[] = $newArr['properties']['hostPoolType'];
  $names[] = $newArr ['name'];
}
// Print the values of the A
foreach($hostpooltype as $value){
  echo $value . "<br>";
}

Try to use array_walk function:

$arr = json_decode($nestedjson);

function recursiveWalk($value, $key)
{
    if (is_array($value)) {
        array_walk($value, "recursiveWalk");
    }
    if (is_object($value)) {
        echo "{$value->properties->hostPoolType}<br>";
    }
}
array_walk($arr, "recursiveWalk");
