    請問一下 PowerOp大大..
    archive.org 要如何找到這篇文章呀???
    我試一下找不到說, 能否請大大教小弟一下..

  2. PowerOp 說道:

    http://www.archive.org/
    或者
    http://www.archive.org/web/web.php
    看到一個"Wayback Machine"的圖示嗎?
    在後面那個http://方框裡面,輸入妳要找的網址,
    例如http://www.cs.wcupa.edu/~rkline/perl2php/
    點選旁邊的"Take me back"按鈕,應該會看到一堆。
    ps:妳的blog雖然有RSS,可是comments沒有,所以我差點漏掉>_

  3. PowerOp 說道:

    方便的話,下次順便寄封信提醒我?
    又,叫我PowerOp就好啦。

  4. yifang 說道:

    為什麼有perl...又要出來一個php?
    php...比perl強嗎?
    看不出來耶...

  5. Tsung 說道:

    @.@a.... 並沒有什麼比什麼強的, 只有適不適合, 熟悉度等問題而已吧~ 🙂

  6. johnpupu 說道:

    補充一下, 統一把筆記做在這 ^^
    php -> continue() = perl -> next()
    php -> break() = perl-> last()

  7. Tsung 說道:

    哈, 感恩, 我不會砍掉的~ 😛

  8. @.@ 說道:

    @.@ 應該會看到
