PHP read Array and Object

I got this array and I want to read the value of "copy01" (in img_4e77e508ab518_197.jpg).

Array ( [0] => stdClass Object ( [meta_value] => O:8:"stdClass":3:{s:6:"copy01";s:25:"img_4e77e508ab518_197.jpg";s:6:"copy02";s:24:"img_4e77e508ab518_80.jpg";s:6:"copy0开发者_运维百科3";s:24:"img_4e77e508ab518_36.jpg";} ) )

This is a print_r($dataOne) and $data_One is a query from the database in WP.

$dataOne = $wpdb->get_results("SELECT meta_value FROM usermeta WHERE umeta_id = '22'");

echo unserialize($dataOne[0]->meta_value)->copy01;

You have an array with a serialized object as the 0th element of the array.

$normalobject = unserialize($dataOne[0]); and var_dump($normalobject); to get an idea of how to read the value.

$dataOne[0]->copy01

how about that?
