My phone won't turn on

Yesterday night I was using my phone and it was working perfectly fine and I put it to charge and went to sleep. I woke up and the phone will not turn on. I tried many different things like holding the power button and holding the power button and the volume button at the same time. I also tried different chargers and all the chargers I tried worked for other devices but not my phone. My phone still won't turn on and I'm wondering if anyone has had this same problem and know how to fix it.
