NI$HANT:

If Output is negative you have to turn the motor in the other direction.

Wasn't able to get it correct, Some more light?

void loop(){ 
  Input = encoder0Pos;
  myPID.Compute();
  if (Output > 0)
     {
     digitalWrite(directionPin, HIGH);
     analogWrite(5,Output);
     }
  else
    {
    digitalWrite(directionPin, LOW);
    analogWrite(5, -Output);
    }
}
