looking good so far, I think you can do the same stripping down you did above, i.e. we want 6 elements from the matrix.

The main reason I use uint32_t here is that we are comparing it to nelems which is a uint32_t

I meant more something like

for (uint32_t i = 0; i < 6; i ++) ..

But I did this, (in a follow-up commit from the one you reviewed?)

if ((zval_affine_elem = zend_hash_index_find_deref(Z_ARRVAL_P(z_affine), i)) != NULL) {
switch (Z_TYPE_P(zval_affine_elem)) {
