base_url() question

Hi,

I`m using url helper. Lets say that all CI files are in app01 folder.
when I

Code:

echo base_url() // return app01/ beacuse of $config['base_url']    = 'app01/';

but why when

Code:

<a href="&lt;?php echo base_url(); ?&gt;main/login">DASBOARD</a>

it returns 127.0.0.1/app01/main/app01/main/login
