$animal = new blueplanetAnimal();
$animal->saveTheWorld('now');
// or
use blueplanet as caprica;
$animal = new capricaAnimal();
$animal->saveTheWorld('now');

namespace foo::bar;
function baz(){ echo "func";}
namespace foo;
class bar {
public static function baz() {
echo "method";
}
}
foo::bar::baz();

$list = array(0, 1, 1, 2, 3, 5, 8,
13, 21, 34, 55, 89);
array_map(
function($n){ return $n * $n;},
$list
);

$lambda = create_function('',
'echo "particles";'
);
$lambda();
$list = array(0, 1, 1, 2, 3, 5, 8, 13, 21, 34,
55, 89);
$func = create_function('$n', 'return $n * $n;');
array_map(
