Installation

It's recommended that you use Composer to install Route.

$ composer require nezamy/route

Route requires PHP 5.4.0 or newer.

Usage

Create an index.php file with the following contents:

<?php
define('DS', DIRECTORY_SEPARATOR, true);
define('BASE_PATH', __DIR__ . DS, TRUE);

require BASE_PATH.'vendor/autoload.php';

$app		= System\App::instance();
$app->request  	= System\Request::instance();
$app->route	= System\Route::instance($app->request);

$route		= $app->route;

$route->any('/', function() {
    echo 'Hello World';
});

$route->end();

If using apache make sure the .htaccess file has exists beside index.php


How it works

Routing is done by matching a URL pattern with a callback function.

$route->any('/', function(){
    echo 'Hello World';
});

$route->any('/about', function(){
    echo 'About';
});


The callback can be any object that is callable. So you can use a regular function:

function pages(){
    echo 'Page Content';
}
$route->get('/', 'pages');

Or a class method:

class home
{
    function pages(){
        echo 'Home page Content';
    }
}
$route->get('/', ['home', 'pages']);
// OR
$home = new home;
$route->get('/', [$home, 'pages']);
// OR
$route->get('/', [email protected]');

Method Routing

$route->any('/', function(){
    // Any method requests
});

$route->get('/', function(){
    // Only GET requests
});

$route->post('/', function(){
    // Only POST requests
});

$route->put('/', function(){
    // Only PUT requests
});

$route->patch('/', function(){
    // Only PATCH requests
});

$route->delete('/', function(){
    // Only DELETE requests
});

// You can use multiple methods. Just add _ between method names.
$route->get_post('/', function(){
    // Only GET and POST request
});

Multiple Routing (All in one)

$route->get(['/', 'index', 'home'], function(){
    // Will match 3 page in one
});

Parameters

// This example will match any page name.
$route->get('/?', function($page){
    echo "you are in $page";
});

// This example will match anything after post/ - limited to 1 argument.
$route->get('/post/?', function($id){
    // Will match anything like post/hello or post/5 ...
    // But not match /post/5/title
    echo "post id $id";
});

// More than parameters
$route->get('/post/?/?', function($id, $title){
    echo "post id $id and title $title";
});
you are in contact
post id 10 and title hello-world

For “unlimited” optional parameters, you can do this:

// This example will match anything after blog/ - unlimited arguments
$route->get('/blog/*', function(){
    // [$this] instanceof ArrayObject so you can get all args by getArrayCopy()
    pre($this->getArrayCopy());
    pre($this[1]);
    pre($this[2]);
});
Array
    (
        [0] => /post/10
        [1] => post
        [2] => 10
    )
post
10

Named Parameters

You can specify named parameters in your routes which will be passed along to your callback function.

$route->get('/{username}/{page}', function($username, $page){
    echo "Username $username and Page $page <br>";
    // OR
    echo "Username {$this['username']} and Page {$this['page']}";
});
Username mahmoud.elnezamy and Page profile
Username mahmoud.elnezamy and Page profile


Regular Expressions

You can validate the args by regular expressions.

// Validate args by regular expressions uses :(your pattern here)
$route->get('/{username}:([0-9a-z_.-]+)/post/{id}:([0-9]+)',
function($username, $id)
{
    echo "author $username post id $id";
});

// You can add named regex pattern in route
$route->addPattern([
    'username' => '/([0-9a-z_.-]+)',
    'id' => '/([0-9]+)'
]);

// Now you can use named regex
$route->get('/{username}:username/post/{id}:id', function($username, $id){
    echo "author $username post id $id";
});

Some named regex pattern already registered in routes

[
    'int'               => '/([0-9]+)',
    'multiInt'          => '/([0-9,]+)',
    'title'             => '/([a-z_-]+)',
    'key'               => '/([a-z0-9_]+)',
    'multiKey'          => '/([a-z0-9_,]+)',
    'isoCode2'          => '/([a-z]{2})',
    'isoCode3'          => '/([a-z]{3})',
    'multiIsoCode2'     => '/([a-z,]{2,})',
    'multiIsoCode3'     => '/([a-z,]{3,})'
]

Optional parameters

You can specify named parameters that are optional for matching by adding (?)

$route->get('/post/{title}?:title/{date}?',
function($title, $date){
    if($title){
        echo "<h1>$title</h1>";
    }else{
        echo "<h1>Posts List</h1>";
    }

    if($date){
        echo "<small>Published $date</small>";
    }
});

post-title

Groups

    // /admin/
    $this->get('/', function(){
        echo 'welcome to admin panel';
    });

    $this->get('/settings', function(){

            echo 'add new user';
        });
