[TYPO3] Getting the alias of Website for a link

[Christian Leicht]

Hello,

can anyone tells me how i can find the alias variable of the current 
website. I need it for the switch between languages(my_languageMenu.php)

Normaly there is the $GLOBALS["TSFE"]->id in use, but i must use the 
alias instead of the id


Where can i find this in the documentation?

Thanks for help


Christian


Detail:
<a class="navi" href="index.php?id='.$GLOBALS["TSFE"]->id.'&L=0" 
target=_top>Flagge der Sprache</a>
