๐ฅAn Fully Automatic, Framework independent, RESTful PHP Router component๐ฅ
๐ฎ๐ณ Made in India ๐ฎ๐ณ
Complete docs can be found here
- Fully automatic, you dont need to define single manual route.
- Support manual route defination for your edge use case.
- No configrations , works out of the box with any php project.
- Stable and well tested.
- Saves lot of time while building RESTful applications
You can install Scrawler Router via Composer. If you don't have composer installed , you can download composer from here
composer require scrawler/router
Note 4.x release changes the way router handles request and response, if you still wanna continue using old way with symfony components goto 3.x branch
<?php
use Scrawler\Router\Router;
$dir = '/path/to/your/controllers';
$namespace = 'Namespace\of\your\controllers';
$router = new Router();
// Register your directory for automatic routing
$router->register($dir,$namespace);
/**
* you can now also enable route caching by passing your own PSR 16 implementation
* $cache = new Psr\SimpleCache\CacheInterface();
* $router->enableCache($cache);
**/
// 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);
//Dispatch route and get back the response
[$status,$handler,$args,$debug] = $router->dispatch($httpMethod,$uri);
switch ($status){
case \Scrawler\Router\Router::NOT_FOUND:
//handle 404 error
// $debug contains extra debug info useful to check failure in automatic routing
break;
case \Scrawler\Router\Router::METHOD_NOT_ALLOWED:
//handle 405 method not allowed
break;
case \Scrawler\Router\Router::FOUND:
//call the handler
$response = call_user_func($handler,...$args);
// Send Response
//echo $response
}
Done now whatever request occurs it will be automatically routed . You don't have define a single route
Information on manual routing can be found in docs
The automatic routing is possible by following some conventions. Lets take a example lets say a controller Hello
<?php
//Hello.php
class Hello
{
public function getWorld()
{
return "Hello World";
}
}
now calling localhost/hello/world
from your browser you will see hello world
on your screen.
Each request to the server is interpreted by Scrawler Router in following way:
METHOD /controller/function/arguments1/arguments2
The controller and function that would be invoked will be
<?php
class Controller
{
public function methodFunction($arguments1, $arguments2)
{
//Definition goes here
}
}
For Example the following call:
GET /user/find/1
would invoke following controller and method
<?php
class User
{
public function getFind($id)
{
//Function definition goes here
}
}
In above example 1
will be passed as argument $id
The function name in the controller should be named according to following convention:
methodFunctionname
Note:The method should always be written in small and the first word of function name should always start with capital.
Method is the method used while calling url. Valid methods are:
all - maps any kind of request method i.e it can be get,post etc
get - mpas url called by GET method
post - maps url called by POST method
put - maps url called by PUT method
delete - maps url called by DELETE method
Some eg. of valid function names are:
getArticles, postUser, putResource
Invalid function names are:
GETarticles, Postuser, PutResource
Scrawler Router uses a special function name allIndex()
and special controller name Main
. So If you want to make a controller for your landing page \
the controller will be defines as follows
// Inside main.php
class Main
{
// All request to your landing page will be resolved to this controller
// ALternatively you can use getIndex() to resolve only get request
public function allIndex()
{
}
}
Class name with Main
signifies special meaning in Scrawler Router , if you wanna define pages route URL you can use main controler
// Inside main.php
class Main
{
// Resolves `/`
public function getIndex()
{
}
// Resolves `/abc`
public function getAbc()
{
}
// Resolves `/hello`
public function getHello()
{
}
}
Just like Main
controller allIndex(), getIndex(), postIndex()
etc signifies a special meaning , urls with only controller name and no function name will try to resolve into this function.
// Inside hello.php
class Hello
{
// Resolves `/hello`
public function getIndex()
{
}
// Resolves `/hello/abc`
public function getAbc()
{
}
}

You may need to add the following snippet in your Apache HTTP server virtual host configuration or .htaccess file.
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L]
Alternatively, if youโre lucky enough to be using a version of Apache greater than 2.2.15, then you can instead just use this one, single line:
FallbackResource /index.php
For IIS you will need to install URL Rewrite for IIS and then add the following rule to your web.config
:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rule name="Toro" stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
<add input="{R:1}" pattern="^(index\.php)" ignoreCase="false" negate="true" />
</conditions>
<action type="Rewrite" url="/index.php/{R:1}" />
</rule>
</rewrite>
</system.webServer>
</configuration>
Under the server
block of your virtual host configuration, you only need to add three lines.
location / {
try_files $uri $uri/ /index.php?$args;
}
