$var[$k0][? $k1][? $k2]++; This is great but the second "?" is redundant isn't it?If the rule is "you cannot read a non-existent array element without ?" then no: $var[$k0][? $k1] allows you to read that element, and from context treat it as an array; but that array won't have a key $k2, so you also need to say that reading *that* was deliberate, and from context treat it as an integer.
