Passing string in url with space

HI , sorry for english , i must send 3 value from get , the first is a url , to have a work value i encode whit :

Code:

<a href="<?=base_url()?>index.php/ranking/match/<?=base64_encode($v->anchor) ?>/<?= $v->team_home  ?>/<?= $v->team_away ?>" class="btnbtn-success">MATCH</a>

In my controller i do a query with the two team but if the team's name have space inside i have error .

I try to encode team to but i have the equal simbol ( = ) at the end and i have  "the uri you submitted has disallowed characters in " error.
