I don't understand. Is this supposed to indicate that PHP is somehow
inefficient at storing array elements?

"a single integer value stored within an PHP array uses 68 bytes: 16
bytes for value structure (zval), 36 bytes for hash bucket, and 2*8 =
16 bytes for memory allocation headers."

That sounds fairly reasonable to me.

Note that each element does not incur a hash bucket. The bucket holds
a list. The blogger just wasn't smart enough to insert enough elements
to see elements hash to the same bucket.
