json - Problem reading stdclass in php?

For example:

<code>array(3) { [0]=> object(stdClass)#6 (2) 
               { ["id"]=> string(1) "1" ["topic_name"]=> string(5) "janus" }
          [1]=> object(stdClass)#7 (2) 
               { ["id"]=> string(2) "10" ["topic_name"]=> string(8) "emulsion" } 
          [2]=> object(stdClass)#33 (2) 
               { ["id"]=> string(2) "14" ["topic_name"]=> string(8) "particle" } }

</code>

What if converted into an array?

If performance is not strictly required and the encoding is utf-8:

<code class="php">$new_array = json_decode(json_encode($array), true);</code>

If there are strict requirements, we can process it in a loop according to the situation

<code class="php">foreach ($array as $key => $value) {
    $array[$key] = (array)$value;
}</code>

Just use foreach

Thank you for the invitation.
Directly operate through the commonly used -> method of obtaining class attributes. If you need to obtain the transformation of any elements, you can use reflection

<code class="php">$reflection = new ReflectionObject($stdClass);
$properties = $target->getProperties();</code>

ReflectionObject::getProperties

Write a function and use array_map
