Well I live in philly PA and when I signed my lease last year my land lord told me it was for one year but I pick it up a year later I see that it's a 2 year I must have missed it cause I just took his word on it but people I know have bin telling me that in pa you can't be held to a lease longer then 1 year every thing afer 1 year is month to month after the 1st year is that true

No, I believe a 2 year lease is allowed as even longer.

A one year lease if not renewed will turn into a month to month.
And normally there will not be an automatic renewal, a new lease will need to be signed.

But if he said one year, before you signed, and signed a 2 year, while he lied, normally things said before are not binding, if it is spelled out specificly in the written lease which should be read before being signed.
