在PHP3中实现SESSION的功能（三、示例程序：test_session.php3）

session|程序|示例

require("cookie.inc.php3");
?>
   session_checkid( 20 ); //20分钟后session失效
    //下面你需要设置mysql的连接参数
    mysql_connect('localhost','user','pass') or Die("can't connect to db!");
?>

This Page should show how to handle the "session.inc.php3" library

We will use a mask with a record showing routine

if( $show ) {
    if( session_read() ) {
        $username = $session[username];
        $userpass = $session[userpass];
        echo "

session[username]:$username
session[userpass]:$userpass";
    }
}
else{
    $session[username]="yourid";
    $session[userpass]="12345";
    if( !session_write() ) {
        print $sess_error;
    }else{
        echo "

session[username]被设置成：$session[username]
" ;
        echo "session[userpass]被设置成：$session[userpass]
" ;
        echo "测试一下SESSION的作用" ;
    }
}
?>
