As you are already married its easy.You need to apply for a residence visa for him,just go to your nearest BOI office and they will give you all the info you need.
A lot of red tape has now been removed from the visa process,as long as he can show he has money and will not be a burden it should be plain sailing.He will also be allowed to work in the Philippines.
Most of the paperwork is down to the wife to complete.
