Unplug IP Phone from PoE switch

Will it cause any harm on the switch side (interface port) or the interface of IP Phone in case I unplug the CAT5 cable on either side ?

This is a question like "will it harm if I plug out my vacuum cleaner from the power outlet?". The answer is yes, it might wear out the plugs :D.
No, it is not dangerous. There is low voltage and current only, and those devices are designed to get an occasional mechanical disconnection. However, they are not designed to be plugged in and out all the time, as all network devices using a physical connection.

Will it easily damage the interface port, on switch or iphone ?

As I see it is common to unplug the cable while the PC is still on, on the server or client side, and I haven't seen any problem on the network interface. Just wonder this is the same for IP phone or not.

It is slightly different, but not harmful. The "harm" is more in the device usually being unusable for much longer if using PoE than if only using LAN connection, because the devices perform a complete reboot. It is like if a PC would have to reboot as soon as you reconnect it to LAN each time.
Mechanical issues are what need to care for. Wear-out of plugs and jacks can be an issue if you are replugging a lot. It's nothing to care about with the cable, but the switch. Note, we are talking about maybe thousands of plugging actions before "issues" might arise.
