利用OCI列出全部数据表'email_info'中的数据 
  同上，只不过用OCI来写
  
  相关PHP代码:

以下是引用片段： PutEnv("ORACLE_SID=ORASID");      $connection = OCILogon ("username","password");   if ($connection == false){    echo OCIError($connection)."   ";    exit;   }      $query = "select * from email_info";   $cursor = OCIParse ($connection, $query);   if ($cursor == false){    echo OCIError($cursor)."   ";    exit;   }      $result = OCIExecute ($cursor);   if ($result == false){    echo OCIError($cursor)."   ";    exit;   }      echo " ";   echo " Full Name Email Address   ";      while (OCIFetchInto ($cursor, $values)){    $name = $values[0];    $email = $values[1];       echo " $name $email   ";   }      echo " ";      OCILogoff ($connection);      ?>
