PHP random tests seem to be off as well.

For: -12dy+9yzd-9dyz-13y+8y-1-11yd+15yd+9y
it expects: 4y-8dy-10dyz

The "1" term should not be there according to the description and the test result makes no sense as a result.

With PHP and for input of 3258336917064184 I get a failed test:

Expected: Array (
0 => 325833691764184
1 => 10
2 => 0
)
Actual : Array (
0 => 325833691764184
1 => 0
2 => 10
)

By the logic of the 209917 example it should be 0,10 and not 10,0 for the i,j combo.
Seems wrong to me. Am I missing something here?
