Phpbb Auto Login Checkbox Code

[dougmcc1]

What does this line mean? It's part of the login script. autologin is a checkbox that tells the cookie to automatically log in the user the next time they visit the board:

$autologin = ( isset($HTTP_POST_VARS['autologin']) ) ? TRUE : 0;

So it gets the value of the checkbox from the form but what does the last part do? (? TRUE : 0)

Nevermind, I got it. If the box is checked then it's TRUE, else it's 0 for FALSE.
