PHP伪静态的几种方法

第一种 通过php程序本身伪静态

访问http://www.domain.com/rewrite.php/2/1.htmL页面打印 $_SERVER全局变量 的结果

Array
(
[HTTP_HOST] => www.duanjuzi.com
[HTTP_USER_AGENT] => Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0
[HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
[HTTP_ACCEPT_LANGUAGE] => zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3
[HTTP_ACCEPT_ENCODING] => gzip, deflate
[HTTP_CONNECTION] => keep-alive
[HTTP_UPGRADE_INSECURE_REQUESTS] => 1
[PATH] => C:\Documents and Settings\All Users\Application Data\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem
[SystemRoot] => C:\WINDOWS
[COMSPEC] => C:\WINDOWS\system32\cmd.exe
[PATHEXT] => .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
[WINDIR] => C:\WINDOWS
[SERVER_SIGNATURE] =>
[SERVER_SOFTWARE] => Apache/2.4.23 (Win32) OpenSSL/1.0.2j PHP/5.4.45
[SERVER_NAME] => www.duanjuzi.com
[SERVER_ADDR] => 127.0.0.1
[SERVER_PORT] => 80
[REMOTE_ADDR] => 127.0.0.1
[DOCUMENT_ROOT] => F:/WWW
[REQUEST_SCHEME] => http
[CONTEXT_PREFIX] =>
[CONTEXT_DOCUMENT_ROOT] => F:/WWW
[SERVER_ADMIN] => admin@phpStudy.net
[SCRIPT_FILENAME] => F:/WWW/rewrite.php
[REMOTE_PORT] => 4769
[GATEWAY_INTERFACE] => CGI/1.1
[SERVER_PROTOCOL] => HTTP/1.1
[REQUEST_METHOD] => GET
[QUERY_STRING] =>
[REQUEST_URI] => /rewrite.php/2/1.htmL
[SCRIPT_NAME] => /rewrite.php
[PATH_INFO] => /2/1.htmL
[PATH_TRANSLATED] => F:\WWW\2\1.htmL
[PHP_SELF] => /rewrite.php/2/1.htmL
[REQUEST_TIME_FLOAT] => 1517382871.093
[REQUEST_TIME] => 1517382871
)

rewrite.php代码如下

<?php
if(@$path_info=$_SERVER["PATH_INFO"]){
  preg_match('/^\/(\d+)\/(\d+).html/',$_SERVER['PATH_INFO'],$arr);
  echo "<pre>";
  print_r($arr);
}
else{
    echo "fail";
}

页面访问/rewrite.php/2/1.html输出内容如下

Array
(
    [0] => /2/1.html
    [1] => 2
    [2] => 1
)

对匹配结果数组$arr

<?php
if(@$path_info=$_SERVER["PATH_INFO"]){
  if(preg_match('/^\/(\d+)\/(\d+).html/',$_SERVER['PATH_INFO'],$arr){
  $type=$arr[1];
  $cid=$arr[2];    //通过$type  $cid变量即可从数据库中获取数据
}
else{
    echo "fail";
}

和访问 /rewrite.php?type=2&cid=1 的效果相同

第二种通过Apache服务器配置伪静态

一、配置虚拟主机需要3个文件
1、Apache/conf/httpd.conf

2、Apache/conf/extra/httpd-vhosts.conf
(这个地版本的apache可能没有，可自己创建，也可以不要此文件，而将配置直接写在httpd.conf里面，写在extra/httpd-vhosts.conf只是为了管理方便，不让httpd.conf文件内容很多而已)

3、C:\WINDOWS\system32\drivers\etc\hosts

二、配置步骤
① httpd.conf 找到VirtualHost example，在后面引入httpd-vhosts.conf文件：
Include conf/extra/httpd-vhosts.conf 这句话，高版本的apache里面已经写有了，只需吧Include前面的#号去掉就OK

② httpd-vhosts.conf配置文件的内容如下：

#
# DocumentRoot 是网站文件存放的根目录
# ServerName 是网站域名, 需要跟 DNS 指向的域名一致
#
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "F:\WWW"
    ServerName www.duanjuzi.com
    ServerAlias www.dummy-host.example.com
#    ErrorLog "logs/dummy-host.example.com-error.log"
#    CustomLog "logs/dummy-host.example.com-access.log" common
     RewriteEngine on    //重写URL规则
     RewriteRule ^/test/([0-9]+).html$ /test.php?id=$1
</VirtualHost>

。。。。。。可以写多个虚拟主机。。。。。。。

③在hosts文件里面增加一句：
127.0.0.1 www.duanjuzi.com

现在访问www.duanjuzi.com就可以访问到F:\WWW这个网站的内容了

现在访问http://www.duanjuzi.com/test/1.html 等同于访问 http://www.duanjuzi.com/test.php?id=1

如果存在同名静态目录文件，会依旧访问动态文件，这时候需要做点设置：

<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "F:\WWW"
    ServerName www.duanjuzi.com
    ServerAlias www.dummy-host.example.com
#    ErrorLog "logs/dummy-host.example.com-error.log"
#    CustomLog "logs/dummy-host.example.com-access.log" common
     RewriteEngine on
     RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f 
     RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d 
     RewriteRule ^/test/([0-9]+).html$ /test.php?id=$1
</VirtualHost>
