How can objects be passed between different PHP files?

To pass objects between different PHP files, you can use sessions or serialization. Sessions allow you to store objects in a session variable that can be accessed across different files, while serialization involves converting an object into a string that can be stored in a file or database and then retrieved and unserialized in another file. 

// File 1: storing an object in a session variable
session_start();
$object = new MyClass();
$_SESSION['myObject'] = $object;

// File 2: retrieving the object from the session variable
session_start();
$object = $_SESSION['myObject'];
```

```php
// File 1: serializing an object and storing it in a file
$object = new MyClass();
file_put_contents('object.txt', serialize($object));

// File 2: retrieving and unserializing the object from the file
$object = unserialize(file_get_contents('object.txt'));
