3、 PHP的安裝和配置
鑒於曾聽說php4.0不支援jpeg（不知記錯沒），我建議還是用php的最新版。
下面的，大家應該熟悉得不能再熟悉了吧？
於是我把php的manual抄下來：
---------------------------------
1. gunzip apache_1.3.x.tar.gz
2. tar xvf apache_1.3.x.tar
3. gunzip php-x.x.x.tar.gz
4. tar xvf php-x.x.x.tar
5. cd apache_1.3.x
6. ./configure --prefix=/www
7. cd ../php-x.x.x
8. 這裡是關鍵！！！
./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars --with-jpeg-dir=/usr/lib --with-gd=/usr/gd-with_gif/lib
當然你也可以加上你自己的選項，此不贅述。
9. make
10. make install
11. cd ../apache_1.3.x
12. for PHP 4: ./configure --activate-module=src/modules/php4/libphp4.a
13. make
14. make install
Instead of this step you may prefer to simply copy the httpd binary
overtop of your existing binary. Make sure you shut down your
server first though.
15. cd ../php-x.x.x
16. for PHP 4: cp php.ini-dist /usr/local/lib/php.ini
You can edit your .ini file to set PHP options. If
you prefer this file in another location, use
--with-config-file-path=/path in step 8.
17. Edit your httpd.conf or srm.conf file and add:
For PHP 4: AddType application/x-httpd-php .php
You can choose any extension you wish here. .php is simply the one
we suggest. You can even include .html .
18. Use your normal procedure for starting the Apache server. (You must
stop and restart the server, not just cause the server to reload by
use a HUP or USR1 signal.)
---------------------------------------
終於成功了，你可以啟動apache用phpinfo()試一試，發現gd那裡：
----------------------
gd
GD Support enabled
GD Version 1.6.2 or higher
GIF Support enabled
PNG Support enabled
JPG Support enabled
WBMP Support enabled
----------------------
^_^哈哈哈哈哈哈哈哈哈^_^
你現在可以用到所有的php圖形函數了：
ImageCreateFromGIF() — Create a new image from file or URL
ImageCreateFromJPEG() — Create a new image from file or URL
ImageCreateFromPNG() — Create a new image from file or URL
……
絕對沒問題！！！！
