Session are handled in
PHP by using the function session_start(). This function should be invoked
before any HTML tags in the script.
Ex.
<?php
session_start( );
?>
<html>
<head> ....... etc
<?php
session_start( );
?>
<html>
<head> ....... etc
A random session id is
generated by the function session_start(). This session id is persisted in a
cookie on the client / user computer. To refer the cookie, the reference
variable $PHPSESSID is used. This is the default session id. The session id can
be changed in the PHP configuration files on the server.
Even the user returns
this page after visiting some pages, PHP keeps track about this session and its
progress. Subsequent to this process, the session can be used as follows –
print $PHPSESSID;
session_register("username");
print $username;
session_register("username");
print $username;
The user name is
registered and by using session variable name username and used it for display.
