How to remove a multidimensional array so that it does not take up RAM?

Answer 1

This should be done by the garbage collector.
And to help him, you can do this:
array = null;

Answer 2

unset($array)

Answer 3

Show your code. Most likely the algorithm is not correct. If, nevertheless, without creating an array, you can’t go anywhere and if you don’t need a guarantee of the safety of this data, then use weak reference. GC will crash them immediately at the first start.
