Hyperlink problem

Hello Everyone
I have some shitty problem right now

when I use

Code:

<a href=""> </a>

its default linked to my existed url

for example condition
my url page is = http://localhost/example/control/user/login

on my html I used

Code:

<a href="&lt;?php echo base_url()?&gt;control/user/register">register</a>
( FYI = my base_url = "http://localhost/example")

when I click the link its direct to
"http://localhost/example/control/user/login/control/user/register"

and I test change my link to

Code:

<a href="www.google.com">register</a>

its directed to
"http://localhost/example/control/user/login/www.google.com"

what I must supposed to do??
regards
