How can sessions be effectively used to maintain object properties across linked PHP files?

To maintain object properties across linked PHP files, sessions can be effectively used by storing the object in the session variable and retrieving it when needed in subsequent files. This ensures that the object properties are preserved and accessible throughout the user's session. 

// File 1: store object in session
session_start();

// create an object
$object = new MyClass();
$object->property = 'value';

// store object in session
$_SESSION['myObject'] = $object;
```

```php
// File 2: retrieve object from session
session_start();

// retrieve object from session
$object = $_SESSION['myObject'];

// access object properties
echo $object->property;
