需要下载的东东：
apache_2.0.59-win32-x86-no_ssl.msi （服务器软件，用来编译PHP的）
php-5.1.5-Win32.zip （PHP的主文件）
第一步：
1．安装apache_2.0.59-win32-x86-no_ssl.msi
2．在C盘建个文件夹叫PHP，把php-5.1.5-Win32.zip压缩到这个文件夹里
第二步：
配置httpd.conf
监听多个端口
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8081
Listen 8082
Listen 8083
#增加监听端口
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 8081
Listen 8082
Listen 8083
#增加监听端口
等以下内容都设置以后，可以通过netstat -n -a查看端口是否开启
开启虚拟站点
# Virtual hosts
#Include conf/extra/httpd-vhosts.conf
#修改为
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
#Include conf/extra/httpd-vhosts.conf
#修改为
# Virtual hosts
Include conf/extra/httpd-vhosts.conf
配置PHP模块
加载php模块,php5apache2_2代表使用的是apache2.2或以上版本
LoadModule php5_module "c:/php/php5apache2_2.dll"
PHPIniDir "C:/php"
PHPIniDir "C:/php"
配置php文件类型映射
AddType application/x-httpd-php .php
配置conf/extra/httpd-vhosts.conf
<VirtualHost *:8082>
ServerAdmin webmaster@dummy-host.localhost
DocumentRoot "C:/PhpDocRoot/Site1"
ServerName localhost
ServerAlias localhost
ErrorLog "logs/dummy-host.localhost-error.log"
CustomLog "logs/dummy-host.localhost-access.log" common

AllowOverride None

Allow from all

</VirtualHost>

<Directory "C:/PhpDocRoot/Site2">

</Directory>
</VirtualHost>
<Directory...>...</Directory>一定不能少
重新启动apache试一下，如果出错，查看一下logs下面的log文件还有windows的事件查看器记录的错误日志。
