Have you read my posts in this thread?

Array filter CREATES new array instead of deleting elements.
If one would like to DELETE element(s) by element value,
array_walk is the way to go.

I suppose I don't have to explain memory and execution
efficiency here. Many people misunderstand the best practice.
This is the reason why I think there should be array_udelete.
