thinkphp Routing rules using sample detailed

  This article mainly introduces the thinkphp routing rules using examples of detailed understanding and pseudo static function implementation (Apache rewrite), need friends can refer to the following

    Code is as follows: <?php //thinkphp routing definition rule   $route = array (  ' news/:action/:yeard/:month/:d ay ' => ' News/read?year=:2&month=:3&day=:4 ',     ' news/:action^delete|update|insert/:yeard/:month/:d ay ' =>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 name $extension = ' html ';  //know: $_server[' path_info ' = ' news/read/2012/2/21/extraparam/test.html '; $REGX = ' news/read/2012/2/21/extraparam/test.html ';  //Loop matching routing rule foreach ($route as $key => $value) { //If the match succeeds, do not continue to match   if Parseurlrule ($key, $value, $REGX, $extension))    break;  //Run results: Print $_get//array//  (//     [actionname] => read//     [modulen AME] => News/     [extra] => 2012     [status] => 1//     [extraparam] => Test//     [year] =>      [month] => 2//     [day] =>//     [finalurl => NEWS/READ?EXTRA=2012&STATUS=1&EXTRAPARAM=TEST&YEAR=2012&MONTH=2&DAY=21// )// [ Finished in 0.6s]  //equivalent to access: http://www.test.com/news/read?extra=2012&status=1&extraparam=test& YEAR=2012&MONTH=2&DAY=21  //In Deployment will hide index.php, open the Apache rewrite module//rewrite rule: Rewriterule  ^ (. +) $  / index.php/$1 //Open, Apache will automatically convert http:/www.test.com/news/read/2012/2/21/extraparam/test.html to http:/ www.test.com/index.php/news/read/2012/2/21/extraparam/test.html  /**  *  @ $rule  string   & nbsp; Routing rules     *  @ $route string     rule mapping new address  *  @ $regx  string     Address bar PathInfo string  *  @ $extension stirng   pseudo-static extension  * &nbsP;return  bool   */function Parseurlrule ($rule, $route, $REGX, $extension =null) {   //remove suffix name    !is_null ($extension) && $regx = Str_replace ('.
