now as far as your other question can you BUY a tourist visa from the thai consulate in Phnom Penh you can. Go to the website, read the requirements, meet the requirements, apply, wait the number of days they take to process visas, go back and pick up your passport with the visa in it. Enter thailand and get stamped in for 60 days (which you can extend by 30 more for 1900baht)
This shows the requirements at the thai consulate in Phnom Penh to get a tourist visa
