What are some best practices for passing data from one PHP file to another, such as from configure.php to install.php?

When passing data from one PHP file to another, one common approach is to use sessions or cookies to store and retrieve the data. In this case, you can set the data in configure.php and then access it in install.php. Another option is to use query parameters in the URL to pass data between files. Lastly, you can also use the $_POST or $_GET superglobals to transfer data between PHP files.

// configure.php
session_start();
$_SESSION['data'] = 'your_data_here';
```

```php
// install.php
session_start();
$data = $_SESSION['data'];
echo $data;
