What are common issues with fetching data in PHP, especially when dealing with multiple objects and classes?

Common issues with fetching data in PHP, especially when dealing with multiple objects and classes, include inconsistent data formats, difficulties in accessing nested properties, and inefficient querying methods. To solve these issues, it is recommended to use object-oriented programming principles, such as encapsulation and inheritance, to organize and retrieve data more effectively. 

class User {
    private $id;
    private $name;
    
    public function __construct($id, $name) {
        $this->id = $id;
        $this->name = $name;
    }
    
    public function getId() {
        return $this->id;
    }
    
    public function getName() {
        return $this->name;
    }
}

$user1 = new User(1, 'Alice');
$user2 = new User(2, 'Bob');

echo $user1->getName(); // Output: Alice
echo $user2->getId(); // Output: 2
