The Code is as follows:

// Thinkphp route definition rules
$ 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 ';

// Suffix
$ Extension = 'html ';

// You Can See That $ _ SERVER ['path _ info'] = 'news/read/2012/2/21/extraparam/test.html ';
$ Regx = 'news/read/2012/2/21/extraparam/test.html ';

// Cyclically match routing rules
Foreach ($ route as $ key => $ value ){
// If the match is successful, the match will not continue
If (parseUrlRule ($ key, $ value, $ regx, $ extension ))
Break;
}

// Run the result: Print $ _ GET
// Array
//(
// [ActionName] => read
// [ModuleName] => news
// [Extra] = & gt; 2012
// [Status] => 1
// [Extraparam] => test
// [Year] = & gt; 2012
// [Month] => 2
// [Day] => 21
// [FinalUrl] => news/read? Extra = 2012 & status = 1 & extraparam = test & year = 2012 & month = 2 & day = 21
//)
// [Finished in 0.6 s]

// Equivalent to access :? Extra = 2012 & status = 1 & extraparam = test & year = 2012 & month = 2 & day = 21

// Index. php is hidden during deployment and the apache rewrite module is enabled.
// Rewrite rule: RewriteRule ^ (. +) $/index. php/$1
// After it is enabled, apache automatically converts http:/www.test.com/news/read/2012/2/21/extraparam/test.htmlto http:/Response
