Can you explain the process of replacing category IDs with category names in PHP arrays when dealing with serialized data?

When dealing with serialized data in PHP arrays that contain category IDs, you can replace the category IDs with category names by first unserializing the data, looping through the array to fetch the category names based on the IDs, and then replacing the IDs with the names. Finally, serialize the array back to its original format with category names instead of IDs. 

// Assume $serializedData is the serialized data containing category IDs
$data = unserialize($serializedData);

// Assume $categories is an array mapping category IDs to category names
foreach ($data as $key => $value) {
    if ($key == 'category_id') {
        $data[$key] = $categories[$value];
    }
}

$updatedSerializedData = serialize($data);
