Hi Sheiman and welcome to Orchid Board.
Congratulations on your first orchid, I'm sure it will be the first of many.
In case you haven't seen it there is a Phal care sheet here.

My main tip, is to let the roots go silver/white between waterings. Water thoroughly each time, let it drain afterwards, then wait till the roots go back to silver before watering again. If possible keep it in a clear pot so you can see the roots.
