利用OCI向数据表 'email_info' 输入数据 同上，只不过用OCI来写   相关PHP代码: if ($submit == "click"){   // The submit button was clicked!   // Get the input for fullname and email then store it in the database.   PutEnv("ORACLE_SID=ORASID");   $connection = OCILogon ("username","password");   if ($connection == false){     echo OCIError($connection)." ";     exit;   }   $query = "insert into email_info values ('$fullname', '$email')";   $cursor = OCIParse ($connection, $query);   if ($cursor == false){     echo OCIError($cursor)." ";     exit;     }   $result = OCIExecute ($cursor);   if ($result == false){     echo OCIError($cursor)." ";     exit;   }   OCICommit ($connection);   OCILogoff ($connection); } else{   echo '      ＜FORM action=insert.php method=post＞     请输入姓名     ＜INPUT name=fullname＞＜/INPUT＞     请输入 Email 地址     ＜INPUT name=email＞＜/INPUT＞     ＜INPUT name=submit type=submit value=click＞＜/INPUT＞              ＜/FORM＞         '; } ?>   对了，这段脚本必须存为insert.php，因为在调用的页面中指定insert.php为表单处理程序
