復制代碼 代碼如下:

$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';
//後綴名
$extension = 'html';
//可知: $_SERVER['PATH_INFO'] = 'news/read/2012/2/21/extraparam/test.html';
$regx = 'news/read/2012/2/21/extraparam/test.html';
//循環匹配路由規則
foreach($route as $key=>$value){
//如果匹配成功,則不繼續匹配
if(parseUrlRule($key,$value,$regx,$extension))
break;
}
//運行結果: 打印$_GET
//Array

// [Finished in 0.6s]
//相當於訪問: http://www.test.com/news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21
//在部署時會把index.php隱藏,開啟apache的重寫模塊
//重寫規則 : RewriteRule ^(.+)$ /index.php/$1
//開啟後,apache會自動把 http:/www.test.com/news/read/2012/2/21/extraparam/test.html轉換為 http:/www.test.com/index.php/news/read/2012/2/21/extraparam/test.html
