session_start(PHP 4, PHP 5) session_start — Initialize session data Description
bool session_start
( void
)
session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie. If you want to use a named session, you must call session_name() before calling session_start(). session_start() will register internal output handler for URL rewriting when trans-sid is enabled. If a user uses ob_gzhandler or like with ob_start(), the order of output handler is important for proper output. For example, user must register ob_gzhandler before session start. Return ValuesThis function returns TRUE if session was started with success otherwise FALSE. Changelog
Examples
Example #1 A session example: page1.php
<?php
After viewing page1.php, the second page page2.php will magically contain the session data. Read the session reference for information on propagating session ids as it, for example, explains what the constant SID is all about.
Example #2 A session example: page2.php
<?php
