php配置路由规则,thinkphp路由规则配置和伪静态功能实现

//thinkphp 路由定义规则

$route = array(

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

'news/:action^delete|update|insert/:yeard/: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

//  (

//      [actionName] => read

//      [moduleName] => news

//      [extra] => 2012

//      [status] => 1

//      [extraparam] => test

//      [year] => 2012

//      [month] => 2

//      [day] => 21

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

//  )

//  [Finished in 0.6s]

//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
