How can session_start() be efficiently implemented using includes or a central bootstrap file?

Session_start() should be efficiently implemented by including it in a central bootstrap file that is included in every page of the application. This ensures that the session is started at the beginning of every script execution, allowing for consistent session management throughout the application. 

```php
// bootstrap.php

session_start();

// Other initialization code can go here
```

Include the bootstrap file at the beginning of every PHP script in your application:

```php
// index.php

include 'bootstrap.php';

// Rest of the code for index.php
```

This way, session_start() is called only once in the bootstrap file, ensuring that the session is started at the beginning of every script execution without the need to call it in every individual file.
