R2
|
|
================
|
|
|
|
libr2 is a DFA URI router library. It compiles your route paths into DFA state
|
|
table, and you may dispatch the URL based on the transition table in C.
|
|
|

|
|
|
|
|
|
|
Use case in PHP
|
|
-----------------------
|
|
|
|
```php
|
|
// Here is the paths data structure
|
|
$paths = [
|
|
'/blog/post/:id' => [ 'controller' => 'PostController', 'action' => 'item', 'method' => 'GET' ],
|
|
'/blog/post' => [ 'controller' => 'PostController', 'action' => 'list', 'method' => 'GET' ],
|
|
'/blog/post' => [ 'controller' => 'PostController', 'action' => 'create', 'method' => 'POST' ],
|
|
'/blog' => [ 'controller' => 'BlogController', 'action' => 'list', 'method' => 'GET' ],
|
|
];
|
|
$rs = r2_compile($paths, 'persisten-table-id');
|
|
$ret = r2_dispatch($rs, '/blog/post/3' );
|
|
list($complete, $route, $variables) = $ret;
|
|
|
|
list($error, $message) = r2_validate($route); // validate route conditions
|
|
if ( $error ) {
|
|
echo $message; // "Method not allowed", "...";
|
|
}
|
|
```
