如何在ZF2中结合较低和喜欢?

How to get SQL like this :

select * from foo where LOWER(foo_name) like '%test%'; 

I know that I can achieve this:

select * from foo where LOWER(foo_name) = 'test';

By:

$where->addPredicate(new Predicate\Expression('LOWER(foo_name) = ?', 'test' ));

And this:

 select * from foo where foo_name like '%test%';

By:

$where->addPredicate( new \Zend\Db\Sql\Predicate\Like('LOWER(foo_name)', '%test%'));

But how to combine the two?

Answer given by @dave works fine.

Even this works -

$where->expression("LOWER(title) LIKE ?", '%test%');

Probably not ideal, but you could do literal:

$where->literal("LOWER(foo_name) LIKE '%test%'");
