thinkphp路由规则使用示例详解和伪静态功能实现(apache重写)

复制代码代码如下:

<?php

//thinkphp 路由定义规则

$route = array(

'news/:action/:year\d/:month/:day'=>'news/read?year=:2&month=:3&day=:4',

'news/:action^delete|update|insert/:year\d/:month/:day'=>array(             'news/read?extra=:2&status=1','year=:2&month=:3&day=:4'),

);

$url= 'http://www.test.com/index.php/news/read/2012/2/21/extraparam/test.html';

//后缀名

$extension = 'html';

//可知: $_SERVER['PATH_INFO'] = 'news/read/2012/2/21/extraparam/test.html';

$regx = 'news/read/2012/2/21/extraparam/test.html';

//循环匹配路由规则

foreach($route as $key=>$value){

//如果匹配成功，则不继续匹配

if(parseUrlRule($key,$value,$regx,$extension))

break;

}

//运行结果：打印$_GET

//Array

//(

//    => read

//    => news

//    => 2012

//    => 1

//    => test

//    => 2012

//    => 2

//    => 21

//    => news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21

//)

//

//相当于访问: http://www.test.com/news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21

//在部署时会把index.php隐藏，开启apache的重写模块

//重写规则： RewriteRule^(.+)$/index.php/$1

//开启后，apache会自动把 http:/www.test.com/news/read/2012/2/21/extraparam/test.html转换为 http:/www.test.com/index.php/news/read/2012/2/21/extraparam/test.html
