Use of ? and : in php statements

[parapet74]

Trying to understand some php code...

 

What do the ? and : operators do? What will be in $s?

 

$cart = $_SESSION['cart'];
$items = explode(',',$cart);
$s = (count($items) > 1) ? 's':'';

It's an alternate syntax for

 

if () { ... } else { ... }

That means if the count of $items is > 1, $s will equal 's', otherwise it will equal nothing ('').

Ah... Thank you.
