Link triggering a function

[smc]

Hiya,

Basically I'm trying to achieve a logout button

Now say I make a function like this

[code=php:0]
function logout(){
    session_destroy();
}
[/code]

How can I incorporate that into a link so when I click on it it ends the session?

Thanks a billion, you guys are very helpful! I can't even fathom how much PHP I've learned in the past 24 hours

Put that on a page and link to the page.

I considered that option I just wanted to see if I could save the extra step.

Oh well nothing ventured nothing gained, thanks!
