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?

Answer 1

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>';
}
?>

Answer 2

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>";
}

Answer 3

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");
