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"; else 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.
