转移了一个比较大的blog到另一台服务器, 出现了下面的提示...请指点..谢谢!

[yufeng]

把blog转移到另一台服务器上, 从apache2.0转移到了apache1.3上. 两个服务器的mysql版本一致, 但是监听的端口不一样, 经过lss的指点, 已经可以连到数据库了....域名指向也进行了转移...基本完成后在访问summary.php页面时在页面最顶端会出现下面的错误提示:

程式碼:

不知道是那里的输出有问题了...请指点...谢谢

不知道是那里的输出有问题了...请指点...谢谢

這個錯誤訊息，通常都是因為自行修改過程式，但是存檔時存成 utf8 with BOM 造成的，請用 utf8 with NO BOM 再存檔一次就行了。

唉~~~ 又是 FAQ

我也遇到類似問題
但我是第一次安裝,也沒修改過
大部分功能都沒問題
但是每一頁都有以下的錯誤碼

程式碼:

請問是什麼問題?
可以解缺嗎?
先謝謝回答

hi bulleta:

如果是新安裝，又沒修改過任何程式的話，那真的很抱歉，你得提供更多訊息(請看如何在論壇發問)才能幫你了。

一般狀況判斷，這都是 BOM 造成的問題

你好, iss:
我的os是windows xp
php是4.3.1,mysql是4.1
安裝目錄是c:\Program Files\Apache Group\Apache\htdocs\plog\
有空格..怎麼辦@@?
在一般閱讀頁面(index.php)會出現以下錯誤碼

程式碼:

C:\Program Files\Apache Group\Apache\htdocs\plog\index.php(50): blogcontroller.process

迴響完成也會只出現以上錯誤碼,但按上一頁可以知道迴響成功的
另外在管理介面全域設定會出現下面的錯誤碼

程式碼:

Parse error: parse error in C:\Program Files\Apache Group\Apache\htdocs\plog\class\template\smarty\Smarty_Compiler.class.php(273) : regexp code on line 2

Fatal error: Failed evaluating code: '{php' . str_repeat(" ", substr_count('{* we have to do it like this... otherwise it doesn''t look nice on the browser textbox *}', " ")) .'}' in C:\Program Files\Apache Group\Apache\htdocs\plog\class\template\smarty\Smarty_Compiler.class.php on line 273

其他功能基本沒問題
有試過1.0.6版本,除了可以閱讀外其他功能完全不能用
而1.1版本出現上面的問題
請問是什麼問題?
怎樣可以記錄時轉成 utf8 with NO BOM ?
最後謝謝ISS的回答@@

[bulleta]

問題解決了
原來只要在php.ini 內output_buffering設定為on就不會出現
謝謝ISS的回答@@

[lss]

hi bulleta:

抱歉，漏掉了你的上一篇文章 sorry

設定 output_buffering = on ，會強迫所有的 PHP 輸出都先 buffer 起來，待完整後再一次輸出。這樣做確實可以解決因 BOM 比 http header 早送出造成的問題，不過對效能會有一些影響。我想，找出出問題的檔案解決 BOM 才是正途，給你參考。

至於怎麼儲存 UTF8 with NO BOM ？一般來說，有支援 UTF8 的文字編輯器都有選項可以處理。我個人喜歡用 notepad++ ，可以用功能表 > 格式 > 編譯成 UTF-8 碼(無 BOM) ，再存檔即可。
