Are there alternative methods to including files in PHP for variable sharing between different systems?

When sharing variables between different systems in PHP, including files is a common method. However, an alternative method is to use sessions to store and retrieve variables across different pages or systems. This allows for more flexibility and control over the shared variables. 

// Start a session
session_start();

// Set a variable in the session
$_SESSION['shared_variable'] = 'value';

// Retrieve the variable in another page or system
$shared_variable = $_SESSION['shared_variable'];
