INI file include_ Ethna & # 92 has been added to path&# 92; The absolute path of class. This path is the path Apache searches when include and require. In addition, I didn't succeed in connecting Oracle with pear:: dB, but I succeeded in connecting mysql. It seems that Oracle can't run because of the SQL statement automatically generated by ehtna. I'm looking for the reason! Good luck
