http://blog.miniasp.com/post/2008/04/How-to-install-PHP4-on-Ubuntu-804-LTS.aspx

據我所知 Ubuntu Linux 大概從 6.06 (Dapper) 開始就不支援 PHP4 了，且 PHP 官方網站也宣布從 2007-12-31 起停止了 PHP4 的計畫（也就是以後也不會再出新版），不過我想應該還是有不少網站是用 PHP4 寫的，要讓這些網站在短時間內全部升級改寫成 PHP5 的版本還真不太容易。今天我也把 Ubuntu 8.04 LTS 裝起來了，並嘗試著也將 php4 裝起來，以下是在 Ubuntu 8.04 成功安裝 php4 的心得分享（當然這個方法在 Ubuntu 6.06, 6.10 或 7.10 一樣適用）。

1. 建立一個檔案到 /etc/apt/sources.list.d/ 目錄下：

# vi /etc/apt/sources.list.d/dapper.sources.list

   檔案內容僅需要輸入一行即可：

deb http://tw.archive.ubuntu.com/ubuntu/ dapper universe main restricted multiverse

2. 執行 apt-get update 指令更新 Packages 資料庫

   你可以發現最後面取得的時 dapper/universe 套件，這裡面就有包括 php4 的所有相關套件。

3. 搜尋所有 php4 相關的套件

root@ubuntu804:~# apt-cache search php4

4. 安裝 php4-cli

root@ubuntu804:~# apt-get install php4-cli 

5. 大功告成！我們來測試一下 php4 是否可以正常執行：

root@ubuntu804:~# php4 -v
PHP Warning:  mime_magic: type search/400       \\input         text/x-tex invalid in Unknown on line 0
PHP Warning:  mime_magic: type search/400       \\section       text/x-tex invalid in Unknown on line 0
PHP Warning:  mime_magic: type search/400       \\setlength     text/x-tex invalid in Unknown on line 0
PHP Warning:  mime_magic: type search/400       \\documentstyle text/x-tex invalid in Unknown on line 0
PHP Warning:  mime_magic: type search/400       \\chapter       text/x-tex invalid in Unknown on line 0
PHP Warning:  mime_magic: type search/400       \\documentclass text/x-tex invalid in Unknown on line 0

  你可以發現執行的過程會出現一堆 PHP Warning 的警告訊息，這是因為 Ubuntu 8.04 中預設的
/usr/share/file/magic.mime (MIME 定義檔) 檔案中有幾行 php4
認不得，而導致出現警示訊息，不過這幾行並不會影響 PHP 的運作。

   因為在 magic.mime 中的這 7 行是用來定義 TeX documents 與 Inform interactive fiction language 的檔案類型，因為很少用到，所以我覺得將這幾行註解掉應該沒關係！所以我們還是修改一下 magic.mime 檔案，將這幾行「太新」的 MIME 定義給註解掉，讓 php4 不會出現警告訊息。你開啟 /usr/share/file/magic.mime 檔案後直接跳到第598行：

# TeX documents, from Daniel Quinlan (quinlan@yggdrasil.com)
0       search/400      \\input         text/x-tex
0       search/400      \\section       text/x-tex
0       search/400      \\setlength     text/x-tex
0       search/400      \\documentstyle text/x-tex
0       search/400      \\chapter       text/x-tex
0       search/400      \\documentclass text/x-tex

# Type: Inform interactive fiction language
# URL:  http://www.inform-fiction.org/
# From: Reuben Thomas <rrt@sc3d.org>
0       regex           [Cc]onstant[[:space:]]+[Ss]tory text/x-inform

這要將這幾行最前面加上井字號 ( # ) 後存檔，然後我們在測試一下 php4 是否正常執行

root@ubuntu804:~# php -v
