对象数组上的array_filter

Question

I have an array of objects. The objects have a is_valid method that has some internal logic and returns either a boolean.

Now I want to get all objects in the array that return true to is_valid. I can do it using a foreach loop.

But is there way to do it using array_filter in PHP without creating a new anonymous or callback function?

The answer is no? http://php.net/manual/en/function.array-filter.php

array_filter
