PHP Shorthand Syntax

Handy shorthand syntax for php. From: http://www.tech-recipes.com/php_programming_tips288.html

A compact (if cryptic) shorthand is useful: 

echo "var is ".($var < 0 ? "negative" : "positive"); 

is equivalent to: 

echo "var is "; 
if ($var < 0) 
    echo "negative"; 
    echo "positive"; 

The shorthand can be considered (expression ? true_value : false_value) where 'expression' is evaluated and, if true, the 'true_value' is returned, otherwise the 'false_value' is returned.
