打开apache的配置文件httpd.conf
找到
#LoadModule rewrite_module modules/mod_rewrite.so
把前面#去掉。没有则添加，但必选独占一行，使apache支持 mod_rewrite 模块

找到
<Directory "D:/ApacheServer/web">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.2/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride None

    #
    # Controls who can get stuff from this server.
    #
    Order allow,deny
    Allow from all

</Directory>
把
AllowOverride None 换成 AllowOverride All 使apache支持 .htaccess 文件

重启apache服务器

在要启用伪静态的 PHP 项目根目录下建立 .htaccess 文件

在 .htaccess 文件中输入内容

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteRule index.html$ index.php
    RewriteRule index-([1-9]+[0-9]*).html$ index.php?p=$1
    RewriteRule ([a-z]{1,})-([0-9]{1,}).html$ index.php?action=$1&id=$2
</IfModule>

注释:
RewriteEngine   为重写引擎开关，on为开启，off为关闭。

RewriteRule     是路由转向规则，$ 之前路径为浏览器中要输入路径，这里可以用正则表达式表达。$+空格 后路径为后台实际转向路径，
转向后台实际路径时可以传参数，例子里的后台页面可以用$_GET['p']   $_GET['action']  $_GET['id'] 来接收
$1 代表浏览器路径中输入的第一个正则表达式的值，以此类推，$2代表第二个正则表达式的值
RewriteRule 路由转向规则里正则表达式用括号 () 括起来


例子所在项目为test
在项目下 index.php 页面内写入内容
<?php
if ($_GET ['p']) {
    echo "p : " . $_GET ['p'];
}

if ($_GET ['action']) {
    echo "action : " . $_GET ['action'];
}

if ($_GET ['id']) {
    echo "id : " . $_GET ['id'];
}
?>

在浏览器中输入
http://localhost/test/index.html
http://localhost/test/index-99.html
http://localhost/test/page-18.html

都会转向 http://localhost/test/index.php 页面
并且依次
http://localhost/test/index.html     页面什么都不显示
http://localhost/test/index-99.html  页面显示 p : 99
http://localhost/test/page-18.html   页面显示 action : pageid : 18
