What is the purpose of using the "exit" function in the PHP code after encoding the error as false?

The purpose of using the "exit" function in PHP after encoding the error as false is to immediately stop the execution of the script and prevent any further processing. This ensures that the error message is returned to the caller without any additional code execution. 

$error = false;

if ($error) {
    echo json_encode(['error' => 'An error occurred']);
    exit;
}

// Continue with the rest of the script if no error
