How to Parse an StdClass object - php

Question

I encoded a MySQL table array to JSON and insert it to a table in specific JSON datatype column because I want to Parse this array into an (HTML table) using PHP of course, so when I run this code block
<?PHP
$stmts = $conn->prepare('SELECT `items` FROM `bills` WHERE id=3');
$stmts->execute();
$result = $stmts->fetchColumn();
$decoded = json_decode($result);
print_r($decoded);
foreach ($decoded[0] as $key => $value) {
echo "<br>Column: ".$key."<br>";
echo "value: ".$value."<br>";
}
?>
I realized that $decoded is a StdClass Object and The Output from print_r is:-
