Phpchina server Relocation, I will basically not go, only with agents, depressed. But with agents incredibly can not post, replies. As a moderator, deeply regret, today with agents to see a few posts, by the way here to answer.
1, we say the URL map it
There are two ways of general URL mapping, one is realized through mod_rewrite, this kind of online teaching material I do not say much. Another is the simulation in the program, such as the Zend framework in the same way/index.php/controller/action/var1/value1/var2/value2/. In fact, the main way is through a unified input interface, and then parse the URL, and finally forwarded to the corresponding controller module.
I've written here two simple functions to simulate.
The first function is mainly for address resolution, the similar/index.php/controller/action/var1/value1/var2/value2/address resolution, generally to parse into three parts: Controller,module, Params.
Copy CodeThe code is as follows:
/**
* Simple parsing of URL routing, support for/path/to/site/index.php/module/action/parm/value
*/path/to/site/index.php?/module/action/parm/value and
*/path/to/site/?/module/action/parm/value three types of treatment
* @param: null
* @return: Router array
*/
function Url_router () {
$path =strip_tags ($_server[' Request_uri ');
$strpos =strpos ($path, '. php ');
if ($strpos) {
$path =substr ($path, $strpos +4);
}else{
if (Empty ($_server[' query_string ')) {
$strpos =strpos ($path, '? ');
if ($strpos) {
$path =substr ($path, $strpos + 1);
}else{
$path = ";
}
}else{
$path =$_server[' query_string '];
}
}
Unify the format of the $path if the first word of $path identifier/is removed
if ($path [0]== '/') {
$path =substr ($path, 1);
}
parsing, and routing
if (!empty ($path)) {
$path =explode ('/', $path);
$router [' Controller ']= $path [0];
$router [' Action ']= (!empty ($path [1])) $path [1]: ' Index ';
Print_r ($path);
for ($i =2; $i $params [$path [$i]]= (Isset ($path [$i +1])? $path [$i +1]: ';
}
$router [' params ']= $params;
}else{
Default Routing information
$router [' controller ']= ' index ';
$router [' Action ']= ' index ';
$router [' params ']=array ();
}
return $router;
}
?>
This completes the main URL parsing function, and then the forwarding map, the following function implementation (Note that this function is implemented in conjunction with my own architecture, so you need to modify the words, of course, if your MVC is similar to the Zend Framework, that should not be much.) ）
Copy CodeThe code is as follows:
function Url_dispatch ($router, $app _path= '/app/controllers/')
{
Require_once (Server_path. ' /libs/controller.class.php ');
$controller = $router [' controller ']. ' Controller ';
echo Server_path. $app _path. $controller. Class.php ';
if (!file_exists (Server_path. $app _path. $controller. Class.php ') Die (' missing the necessary class! ');
Require_once (Server_path. $app _path. $controller. Class.php ');
$controller =new $controller ();
$controller->_setparam ($router [' params ']);
$controller->{$router [' Action ']. Action '} ();
return true;
}
?>
