Variable variables and functions without a doubt!

$foo = 'bar';
$bar = 'foobar';
echo $$foo;    //This outputs foobar

function bar() {
    echo 'Hello world!';
}

function foobar() {
    echo 'What a wonderful world!';
}
$foo();    //This outputs Hello world!
$$foo();    //This outputs What a wonderful world!

The same concept applies to object parameters ($some_object->$some_variable);

Very, very nice. Make's coding with loops and patterns very easy, and it's faster and more under control than eval (Thanx @Ross & @Joshi Spawnbrood!).t
