Title

Suppose now there is an empty array of 1000 elements, now to randomly insert 5 first prize, randomly insert 10 second prize, randomly insert 20 third prize, the rest are not winning

That is, the 1000 elements must have 5 first Prize 10 second prize 20 third prize other not winning

How to achieve it?

------Solution--------------------
$ar = Array_merge (Array_fill (0, 5, 1), Array_fill (0, ten, 2), Array_fill (0,, 3), Array_fill (0, 965, 0));
Shuffle ($ar);

$ar is the array you need
