How can PHP developers efficiently handle sessions on every page without repeating the session_start() command?
PHP developers can efficiently handle sessions on every page without repeating the session_start() command by using a common include file that is included on every page. This file can contain the session_start() command, ensuring that sessions are started on every page without the need to repeat the command in each individual file.
// session_start.php
session_start();
// index.php
include('session_start.php');
// other_page.php
include('session_start.php');
