Understanding the Difference Between PE=MGH and PE=GmM/r^2 in Online Discussions

[Kyle Barr]

I am from New York, and a physics student. ( not trying to give to much info on the internet.) but i was curious in why people on the internet use PE equation as GmM/r^2 when i was taught that it was PE=MGH? please help me with me confusion? thank you.
