They are still legal over here in the UK but they've become hard to get hold of since most suppliers lost their suppliers in the US. I think they're still legal in Canada too.
I have recently spotted PH on a UK website but I didn't bookmark it so can't give you a link. Given that they are illegal in the States I suspect that the board would react badly to any links being posted, anyway. Look around all the UK supplement suppliers, I'm sure you'll stumble across some at a price that's been ridiculously inflated due to the shortage.
