How can PHP developers ensure proper class initialization and object passing to avoid errors or unexpected behavior?

To ensure proper class initialization and object passing in PHP, developers should utilize constructor methods to set initial values for class properties and pass objects by reference to avoid unexpected behavior. By properly initializing classes and passing objects correctly, developers can prevent errors and ensure the intended functionality of their code. 

class MyClass {
    private $value;

    public function __construct($value) {
        $this->value = $value;
    }

    public function getValue() {
        return $this->value;
    }
}

// Create an instance of MyClass with proper initialization
$myObject = new MyClass("Hello");

// Pass the object by reference to another function
function updateObject(MyClass &$object, $newValue) {
    $object = new MyClass($newValue);
}

// Call the function to update the object
updateObject($myObject, "World");

// Output the updated value
echo $myObject->getValue(); // Output: World
