iPhone 6 won't connect to iTunes on PC and won't charge?

I have had problems for a few days with connecting my charger and getting the iPhone to charge and now it won't charge and won't connect to iTunes on my PC. I have tried two different Apple chargers and Apple leads with the same result. A friends charger also would not work with my iPhone.

Hi, welcome to iMore.
It could be dust. You can remove dust from the lightning port with a toothpick by very very gently removing the dust with it. Good luck.
