R2
libr2 is an URI router library. It compiles your route paths into a radix tree. By using the constructed radix tree in the start-up time, you may dispatch your routes efficiently.
Pattern Syntax
/blog/post/{id} use [^/]+ regular expression by default.
/blog/post/{id:\d+} use `\d+` regular expression instead of default.
Use case in 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' ] ,
];
$rs = r2_compile_radix($paths, 'persisten-table-id');
$ret = r2_dispatch_radix($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", "...";
}
