What are the best practices for accessing nested levels of stdClass Objects in PHP?

When accessing nested levels of stdClass Objects in PHP, it is important to check if each level exists before attempting to access it to avoid errors. One way to do this is by using isset() or property_exists() functions to verify the existence of each level before accessing it. 

// Example of accessing nested levels of stdClass Objects in PHP

// Assuming $obj is a stdClass object with nested levels
if (isset($obj->level1) && isset($obj->level1->level2) && isset($obj->level1->level2->level3)) {
    $value = $obj->level1->level2->level3;
    // Do something with $value
} else {
    // Handle the case where the nested levels do not exist
}
