Orchid seed pods look very much like a vanilla "bean", another species of Orchid.
I have never seen any seed on my Phals. I believe they need a special pollinator or to be hand pollinated. Orchid seed is dust fine and has special growing requirements. Plants can take years before they bloom.

Google orchid seed pods and orchid pollination. That should give you some basic info...there's a lot to it... really hard to explain
