雖然我是用phpbb2 plus 1.3的, 但我想引言回覆應該跟phpbb都一樣吧？而且我想這問題也不一定是phpbb的問題, 我在懷疑究竟是不是apache太舊了, 但我又找不到redhat7.3可以用的apache新版, 都不敢亂動
大家有看過資料庫都應該知道, 引言回覆在資料庫會是這樣的

我在舊機器時bbcode_uid還是會乖乖出來的, 一切正常
但一搬到新機器的時候, bbcode_uid新不見了,變成這樣\r

我研究過在引言回覆時由瀏覽器傳回伺服器時回覆回容會經過這個在includes/bbcode.php敘述\r

由此可見把引言回覆加上bbcode_uid就是bbencode_first_pass_pda這個function, 但我實在看不懂這個function在寫什麼…而且也不明白為什麼兩台機器跑同一個function, 一台做得到, 一台卻沒反應, 我在這貼出這個function的內容, 希望有人能幫幫看看為什麼會不行, 究竟是不是apache太舊而沒法用盡php而令某些敘述跑不動呢？[quote:bbcode_uid="我的名字"]引言內容[/quote:bbcode_uid]
