(Ovid) Re: 3 strings to join

You might find the following syntax a bit clearer.

if ( $b and $c ) {
    $string = "$a where $b and $c";
} elsif ( $b or $c ) {
    $string = "$a where " . ($b ? $b : $c) ;
}

This relies on using the ternary operator: condition ? true : false Let's say you have the following line:

$x = $b ? 5 : 17;

If $b evaluates as true, $x will be set to 5. Otherwise, it will be set to 17.

(Sorry if I seem pedantic. Not sure if you'd seen it before).

actually I have seen it, but it's one of those things I read about and then say "what could I use that for?", move on, hit an issue and then someone as enlightened as yourself says "You could do this." and I have a small psychotic break (or satori, whatever you prefer :) ...and then the monk gained enlightenment? -- I'm a solipsist, and so is everyone else.
