Electrical outlets in The Philippines are similar to those in the U.S., although some may not be "polarized" (meaning that both slots are the same size instead of one being larger). If your plug is polarized, you'll need an adapter. A 3-pack is $13 from Amazon.
The bigger issue is that the power is 220-volt rather than 120-volt.
Apple products and most other electronics work fine at 220-volt and the plugs are not polarized, but carefully check the information on your charger. If the charger doesn't say "INPUT: 110-240V", you will need a power adaptor.
