Multiple choices .. if / else

entangled

What do they call something like this ...

<?=(($data->link_place == "T") ? "Top bar":"Main menu bar")?>

... it's sort of a if /else statement. But what if there are three possiblities

T = Top bar
M = Main menu bar
N = No menu

Would I have to use a normal if / ifelse / else statment?

Yes.

That is known as the conditional/ternary operator.

Thanks Mark. The link was very help too ... in my case, according to the link, with PHP, the above statement would turn into:

Expand|Select|Wrap|Line Numbers

 <?php

$arg = "T";

$link_place= ($arg == 'T') ? 'Top bar' :

          (($arg == 'S') ? 'Main menu bar' :

          'Not in menu'));

echo $link_place;

?>

Yes, but I wouldn't write it as such because it isn't too easy to read, whereas the following is easy to read:

Expand|Select|Wrap|Line Numbers

 
switch ($arg) {

    case 'T': $link_place = 'Top bar';

        break;

    case 'S': $link_place = 'Main menu bar';

        break;

    default: $link_place = 'Not in menu';

        break;

}
