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" ;
}
}
?>
