How do I determine if an array is empty in PHP?

I want to check that an array has no values or that the values in the array are empty. Can someone explain how to do this?

Someday I've learned very smart solution here on SO

if(!array_filter($array)) {
  //array contains only empty values
}

or even smarter one (if applicable):

if(!array_filter($array,'trim')) {
  //array contains only empty values
}
