This is most likely a server/environment configuration issue, not your business logic. 1.Your include_path points to /home/us_pear/PEAR, but that directory doesn’t exist → PEAR is not installed (or installed elsewhere). 2.${US_ROOTF} is probably not being expanded, so the path becomes /home/us_pear/PEAR. 3.On Linux, include_path should typically use : as the separator, not ;.
