+FastRoute - Fast request router for PHP
+=======================================
+
+This library provides a fast implementation of a regular expression based router. [Blog post explaining how the
+implementation works and why it is fast.][blog_post]
+
+Install
+-------
+
+To install with composer:
+
+```sh
+composer require nikic/fast-route
+```
+
+Requires PHP 5.4 or newer.
+
+Usage
+-----
+
+Here's a basic usage example:
+
+```php
+<?php
+
+require '/path/to/vendor/autoload.php';
+
+$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
+    $r->addRoute('GET', '/users', 'get_all_users_handler');
+    // {id} must be a number (\d+)
+    $r->addRoute('GET', '/user/{id:\d+}', 'get_user_handler');
+    // The /{title} suffix is optional
+    $r->addRoute('GET', '/articles/{id:\d+}[/{title}]', 'get_article_handler');
+});
+
+// Fetch method and URI from somewhere
+$httpMethod = $_SERVER['REQUEST_METHOD'];
+$uri = $_SERVER['REQUEST_URI'];
+
+// Strip query string (?foo=bar) and decode URI
+if (false !== $pos = strpos($uri, '?')) {
+    $uri = substr($uri, 0, $pos);
+}
+$uri = rawurldecode($uri);
+
+$routeInfo = $dispatcher->dispatch($httpMethod, $uri);
+switch ($routeInfo[0]) {
+    case FastRoute\Dispatcher::NOT_FOUND:
+        // ... 404 Not Found
+        break;
+    case FastRoute\Dispatcher::METHOD_NOT_ALLOWED:
+        $allowedMethods = $routeInfo[1];
+        // ... 405 Method Not Allowed
+        break;
+    case FastRoute\Dispatcher::FOUND:
+        $handler = $routeInfo[1];
+        $vars = $routeInfo[2];
+        // ... call $handler with $vars
+        break;
+}
+```
+
+### Defining routes
+
+The routes are defined by calling the `FastRoute\simpleDispatcher()` function, which accepts
+a callable taking a `FastRoute\RouteCollector` instance. The routes are added by calling
+`addRoute()` on the collector instance:
+
+```php
+$r->addRoute($method, $routePattern, $handler);
+```
+
+The `$method` is an uppercase HTTP method string for which a certain route should match. It
+is possible to specify multiple valid methods using an array:
+
+```php
+// These two calls
+$r->addRoute('GET', '/test', 'handler');
+$r->addRoute('POST', '/test', 'handler');
+// Are equivalent to this one call
+$r->addRoute(['GET', 'POST'], '/test', 'handler');
+```
+
+By default the `$routePattern` uses a syntax where `{foo}` specifies a placeholder with name `foo`
+and matching the regex `[^/]+`. To adjust the pattern the placeholder matches, you can specify
+a custom pattern by writing `{bar:[0-9]+}`. Some examples:
+
+```php
+// Matches /user/42, but not /user/xyz
+$r->addRoute('GET', '/user/{id:\d+}', 'handler');
+
+// Matches /user/foobar, but not /user/foo/bar
+$r->addRoute('GET', '/user/{name}', 'handler');
+
+// Matches /user/foo/bar as well
+$r->addRoute('GET', '/user/{name:.+}', 'handler');
+```
+
+Custom patterns for route placeholders cannot use capturing groups. For example `{lang:(en|de)}`
+is not a valid placeholder, because `()` is a capturing group. Instead you can use either
+`{lang:en|de}` or `{lang:(?:en|de)}`.
+
+Furthermore parts of the route enclosed in `[...]` are considered optional, so that `/foo[bar]`
+will match both `/foo` and `/foobar`. Optional parts are only supported in a trailing position,
+not in the middle of a route.
+
+```php
+// This route
+$r->addRoute('GET', '/user/{id:\d+}[/{name}]', 'handler');
+// Is equivalent to these two routes
+$r->addRoute('GET', '/user/{id:\d+}', 'handler');
+$r->addRoute('GET', '/user/{id:\d+}/{name}', 'handler');
+
+// Multiple nested optional parts are possible as well
+$r->addRoute('GET', '/user[/{id:\d+}[/{name}]]', 'handler');
+
+// This route is NOT valid, because optional parts can only occur at the end
+$r->addRoute('GET', '/user[/{id:\d+}]/{name}', 'handler');
+```
+
+The `$handler` parameter does not necessarily have to be a callback, it could also be a controller
+class name or any other kind of data you wish to associate with the route. FastRoute only tells you
+which handler corresponds to your URI, how you interpret it is up to you.
+
+#### Shorcut methods for common request methods
+
+For the `GET`, `POST`, `PUT`, `PATCH`, `DELETE` and `HEAD` request methods shortcut methods are available. For example:
+
+```php
+$r->get('/get-route', 'get_handler');
+$r->post('/post-route', 'post_handler');
+```
+
+Is equivalent to:
+
+```php
+$r->addRoute('GET', '/get-route', 'get_handler');
+$r->addRoute('POST', '/post-route', 'post_handler');
+```
+
+#### Route Groups
+
+Additionally, you can specify routes inside of a group. All routes defined inside a group will have a common prefix.
+
+For example, defining your routes as:
+
+```php
+$r->addGroup('/admin', function (RouteCollector $r) {
+    $r->addRoute('GET', '/do-something', 'handler');
+    $r->addRoute('GET', '/do-another-thing', 'handler');
+    $r->addRoute('GET', '/do-something-else', 'handler');
+});
+```
+
+Will have the same result as:
+
+ ```php
+$r->addRoute('GET', '/admin/do-something', 'handler');
+$r->addRoute('GET', '/admin/do-another-thing', 'handler');
+$r->addRoute('GET', '/admin/do-something-else', 'handler');
+ ```
+
+Nested groups are also supported, in which case the prefixes of all the nested groups are combined.
+
+### Caching
+
+The reason `simpleDispatcher` accepts a callback for defining the routes is to allow seamless
+caching. By using `cachedDispatcher` instead of `simpleDispatcher` you can cache the generated
+routing data and construct the dispatcher from the cached information:
+
+```php
+<?php
+
+$dispatcher = FastRoute\cachedDispatcher(function(FastRoute\RouteCollector $r) {
+    $r->addRoute('GET', '/user/{name}/{id:[0-9]+}', 'handler0');
+    $r->addRoute('GET', '/user/{id:[0-9]+}', 'handler1');
+    $r->addRoute('GET', '/user/{name}', 'handler2');
+}, [
+    'cacheFile' => __DIR__ . '/route.cache', /* required */
+    'cacheDisabled' => IS_DEBUG_ENABLED,     /* optional, enabled by default */
+]);
+```
+
+The second parameter to the function is an options array, which can be used to specify the cache
+file location, among other things.
+
+### Dispatching a URI
+
+A URI is dispatched by calling the `dispatch()` method of the created dispatcher. This method
+accepts the HTTP method and a URI. Getting those two bits of information (and normalizing them
+appropriately) is your job - this library is not bound to the PHP web SAPIs.
+
+The `dispatch()` method returns an array whose first element contains a status code. It is one
+of `Dispatcher::NOT_FOUND`, `Dispatcher::METHOD_NOT_ALLOWED` and `Dispatcher::FOUND`. For the
+method not allowed status the second array element contains a list of HTTP methods allowed for
+the supplied URI. For example:
+
+    [FastRoute\Dispatcher::METHOD_NOT_ALLOWED, ['GET', 'POST']]
+
+> **NOTE:** The HTTP specification requires that a `405 Method Not Allowed` response include the
+`Allow:` header to detail available methods for the requested resource. Applications using FastRoute
+should use the second array element to add this header when relaying a 405 response.
+
+For the found status the second array element is the handler that was associated with the route
+and the third array element is a dictionary of placeholder names to their values. For example:
+
+    /* Routing against GET /user/nikic/42 */
+
+    [FastRoute\Dispatcher::FOUND, 'handler0', ['name' => 'nikic', 'id' => '42']]
+
+### Overriding the route parser and dispatcher
+
+The routing process makes use of three components: A route parser, a data generator and a
+dispatcher. The three components adhere to the following interfaces:
+
+```php
+<?php
+
+namespace FastRoute;
+
+interface RouteParser {
+    public function parse($route);
+}
+
+interface DataGenerator {
+    public function addRoute($httpMethod, $routeData, $handler);
+    public function getData();
+}
+
+interface Dispatcher {
+    const NOT_FOUND = 0, FOUND = 1, METHOD_NOT_ALLOWED = 2;
+
+    public function dispatch($httpMethod, $uri);
+}
+```
+
+The route parser takes a route pattern string and converts it into an array of route infos, where
+each route info is again an array of it's parts. The structure is best understood using an example:
+
+    /* The route /user/{id:\d+}[/{name}] converts to the following array: */
+    [
+        [
+            '/user/',
+            ['id', '\d+'],
+        ],
+        [
+            '/user/',
+            ['id', '\d+'],
+            '/',
+            ['name', '[^/]+'],
+        ],
+    ]
+
+This array can then be passed to the `addRoute()` method of a data generator. After all routes have
+been added the `getData()` of the generator is invoked, which returns all the routing data required
+by the dispatcher. The format of this data is not further specified - it is tightly coupled to
+the corresponding dispatcher.
+
+The dispatcher accepts the routing data via a constructor and provides a `dispatch()` method, which
+you're already familiar with.
+
+The route parser can be overwritten individually (to make use of some different pattern syntax),
+however the data generator and dispatcher should always be changed as a pair, as the output from
+the former is tightly coupled to the input of the latter. The reason the generator and the
+dispatcher are separate is that only the latter is needed when using caching (as the output of
+the former is what is being cached.)
+
+When using the `simpleDispatcher` / `cachedDispatcher` functions from above the override happens
+through the options array:
+
+```php
+<?php
+
+$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
+    /* ... */
+}, [
+    'routeParser' => 'FastRoute\\RouteParser\\Std',
+    'dataGenerator' => 'FastRoute\\DataGenerator\\GroupCountBased',
+    'dispatcher' => 'FastRoute\\Dispatcher\\GroupCountBased',
+]);
+```
+
+The above options array corresponds to the defaults. By replacing `GroupCountBased` by
+`GroupPosBased` you could switch to a different dispatching strategy.
+
+### A Note on HEAD Requests
+
+The HTTP spec requires servers to [support both GET and HEAD methods][2616-511]:
+
+> The methods GET and HEAD MUST be supported by all general-purpose servers
+
+To avoid forcing users to manually register HEAD routes for each resource we fallback to matching an
+available GET route for a given resource. The PHP web SAPI transparently removes the entity body
+from HEAD responses so this behavior has no effect on the vast majority of users.
+
+However, implementers using FastRoute outside the web SAPI environment (e.g. a custom server) MUST
+NOT send entity bodies generated in response to HEAD requests. If you are a non-SAPI user this is
+*your responsibility*; FastRoute has no purview to prevent you from breaking HTTP in such cases.
+
+Finally, note that applications MAY always specify their own HEAD method route for a given
+resource to bypass this behavior entirely.
+
+### Credits
+
+This library is based on a router that [Levi Morrison][levi] implemented for the Aerys server.
+
+A large number of tests, as well as HTTP compliance considerations, were provided by [Daniel Lowrey][rdlowrey].

+PHP Parser
+==========
+
+[![Coverage Status](https://coveralls.io/repos/github/nikic/PHP-Parser/badge.svg?branch=master)](https://coveralls.io/github/nikic/PHP-Parser?branch=master)
+
+This is a PHP parser written in PHP. Its purpose is to simplify static code analysis and
+manipulation.
+
+[**Documentation for version 5.x**][doc_master] (current; for running on PHP >= 7.4; for parsing PHP 7.0 to PHP 8.4, with limited support for parsing PHP 5.x).
+
+[Documentation for version 4.x][doc_4_x] (supported; for running on PHP >= 7.0; for parsing PHP 5.2 to PHP 8.3).
+
+Features
+--------
+
+The main features provided by this library are:
+
+ * Parsing PHP 7, and PHP 8 code into an abstract syntax tree (AST).
+   * Invalid code can be parsed into a partial AST.
+   * The AST contains accurate location information.
+ * Dumping the AST in human-readable form.
+ * Converting an AST back to PHP code.
+   * Formatting can be preserved for partially changed ASTs.
+ * Infrastructure to traverse and modify ASTs.
+ * Resolution of namespaced names.
+ * Evaluation of constant expressions.
+ * Builders to simplify AST construction for code generation.
+ * Converting an AST into JSON and back.
+
+Quick Start
+-----------
+
+Install the library using [composer](https://getcomposer.org):
+
+    php composer.phar require nikic/php-parser
+
+Parse some PHP code into an AST and dump the result in human-readable form:
+
+```php
+<?php
+use PhpParser\Error;
+use PhpParser\NodeDumper;
+use PhpParser\ParserFactory;
+
+$code = <<<'CODE'
+<?php
+
+function test($foo)
+{
+    var_dump($foo);
+}
+CODE;
+
+$parser = (new ParserFactory())->createForNewestSupportedVersion();
+try {
+    $ast = $parser->parse($code);
+} catch (Error $error) {
+    echo "Parse error: {$error->getMessage()}\n";
+    return;
+}
+
+$dumper = new NodeDumper;
+echo $dumper->dump($ast) . "\n";
+```
+
+This dumps an AST looking something like this:
+
+```
+array(
+    0: Stmt_Function(
+        attrGroups: array(
+        )
+        byRef: false
+        name: Identifier(
+            name: test
+        )
+        params: array(
+            0: Param(
+                attrGroups: array(
+                )
+                flags: 0
+                type: null
+                byRef: false
+                variadic: false
+                var: Expr_Variable(
+                    name: foo
+                )
+                default: null
+            )
+        )
+        returnType: null
+        stmts: array(
+            0: Stmt_Expression(
+                expr: Expr_FuncCall(
+                    name: Name(
+                        name: var_dump
+                    )
+                    args: array(
+                        0: Arg(
+                            name: null
+                            value: Expr_Variable(
+                                name: foo
+                            )
+                            byRef: false
+                            unpack: false
+                        )
+                    )
+                )
+            )
+        )
+    )
+)
+```
+
+Let's traverse the AST and perform some kind of modification. For example, drop all function bodies:
+
+```php
+use PhpParser\Node;
+use PhpParser\Node\Stmt\Function_;
+use PhpParser\NodeTraverser;
+use PhpParser\NodeVisitorAbstract;
+
+$traverser = new NodeTraverser();
+$traverser->addVisitor(new class extends NodeVisitorAbstract {
+    public function enterNode(Node $node) {
+        if ($node instanceof Function_) {
+            // Clean out the function body
+            $node->stmts = [];
+        }
+    }
+});
+
+$ast = $traverser->traverse($ast);
+echo $dumper->dump($ast) . "\n";
+```
+
+This gives us an AST where the `Function_::$stmts` are empty:
+
+```
+array(
+    0: Stmt_Function(
+        attrGroups: array(
+        )
+        byRef: false
+        name: Identifier(
+            name: test

+                attrGroups: array(
+                )
+                type: null

+        returnType: null
+        stmts: array(
+        )
+    )
+)
+```
+
+Finally, we can convert the new AST back to PHP code:
+
+```php
+use PhpParser\PrettyPrinter;
+
+$prettyPrinter = new PrettyPrinter\Standard;
+echo $prettyPrinter->prettyPrintFile($ast);
+```
+
+This gives us our original code, minus the `var_dump()` call inside the function:
+
+```php
+<?php
+
+function test($foo)
+{
+}
+```
