How to Transform an stdClass Object into an Array in PHP

In PHP, it's possible to encounter instances where an stdClass object is acquired from queries like $wpdb->get_results. To effectively process and manipulate this object, converting it to an array is often necessary.

Here are two practical approaches to achieve this array transformation:

JSON Encoding and Decoding:

The simplest method involves encoding the object as JSON and subsequently decoding the JSON string back into an array:

$array = json_decode(json_encode($object), true);

Manual Traversal:

If preferred, you can manually traverse the object and extract the data into an array:

foreach ($object as $value) {
    $array[] = $value->post_id;
}

This will generate an array of post IDs, which you can easily access and utilize.
