The ?: is the ternary operator for doing an if/else as an expression. For instance... an if/else block can't be used on the right side of an asignment operator or inside an expression.

$(is_array($var)) ? print  "true\n" : print "false\n";

is analogus to:

if (is_array($var)) 
	print  "true\n";
else
	print "false\n";

so you can say

$somevar = $(is_array($var)) ? true : false;

You can get really tricky with this inside complex expressions.
