Table of Contents


Dispatch requires PHP 5.4+ to run.


Download and include the file dispatch.php directly or install it using composer:

$ composer require badphp/dispatch

Application Entry Point

Request handling and route matching starts after you call dispatch().

# serve request

You can pass variables to your handlers by passing them as arguments to dispatch().

# map a handler that expects the db conn
map('GET', '/users/list', function ($db) {
  # ... do something with $db

# some resource, etc.
$db = new Connection();

# args you pass to dispatch() gets forwarded


Route handlers are mapped using the map() function.

# map handler against method(s) + route
map('POST', '/users/create', function () {});
map(['HEAD', 'GET', 'OPTIONS'], '/users/<id>', function () {});

# map handler against a route(s) + any method
map('/about', function () {});
map(['/about', '/contact'], function () {});

# map handler against everything
map(function () {});

For POST requests, If you have x-http-method-override set, that will be used. If not, it checks for $_POST['_method'] and uses that if found.

Route Parameters

Routes can have parameter values. When specified, their matching values are passed into your handler via a hash.

# if you have route symbols, a hash of their values will be passed first
map('GET', '/users/<id>', function ($params) {
  $id = $params['id'];

# you can attach regex rules to your route symbols as well
map('GET', '/users/<id:\d{2,5}>', function ($params) {
  # {id} will match 12, but not 1, or 123456

# if you have args from dispatch(), they will come after the params hash
map('GET', '/topics/<id>', function ($params, $db) {
  $id = $params['id'];

# pass an argument during dispatch

Route Parameter Hooks

In some cases, we want to preload some data associated with a route parameter value. We can do this with route parameter hooks via hook().

# if <id> is in the matching route, replace it
hook('id', function ($id) {
  return [$id, md5($id)];

# handler can expect modified data
map('GET', '/users/<id>', function ($params) {
  list($id, $id_md5) = $params['id'];

Error Handlers

HTTP error handlers are mapped using the same map() function, but instead of the usual method + route + action arguments, you just pass the http code and action.

# map handler against error codes, first argument is the error code
map(404, function ($code) {});
map([400, 401, 403, 404], function ($code) {});

You can then trigger the HTTP error handler with error().

# trigger an error handler for the code

You can also pass arguments to your error handler by passing them along in your error() call.

# expect a resource (2nd argument) in your error handler
map(404, function ($code, $res) {
  # ... do something with $res

# trigger an error handler while passing an argument
error(404, $some_resource);


Page redirects are done with redirect(), which can also finish script execution if $halt is true.

# default, redirect with 302 and don't end execution
return redirect('/new-location');

# redirect with a specific code, and terminate
return redirect('/new-location', 301, $halt = true);

PHP Templates

Render PHP templates using the phtml() function. This function assumes your that your templates end in .phtml.

# render partial file hello.phtml
$partial = phtml(__DIR__.'/views/hello', ['name' => 'stranger'], false);

To use layout templates, provide a section in your template that prints out the contents of $body.

<!-- views/layout.phtml -->
<body><?php echo $body ?></body>
# render hello.phtml inside layout.phtml
echo phtml(
  ['name' => 'stranger'],

For convenience, you can Tell dispatch where to find templates by setting the templates setting via config().

; config.ini
templates = ./views
# load config

# get a partial
$partial = phtml('hello', ['name' => 'stranger'], false);

# render page
echo phtml('hello', ['name' => 'stranger'], 'layout');


Load, set and access configuration settings via the config() function. Pass a hash to config() to set multiple settings at once, a string to fetch the configuration value for that key, or a string and a value, to set the value for that configuration key.

; config.ini
some_setting_1 = yes
some_setting_2 = foo

We then load the values in the following way:

# initialize the config container

# set a config value
config('my_custom_config', 'foobar');

# fetch some values
$some_setting_1 = config('some_setting_1');
$some_setting_2 = config('some_setting_2');

The following configuration entries change some of Dispatch's behavior.

; your applications base URL
url = http://localhost/myapp

; if you don't have access to URL rewrites (this gets stripped)
router = index.php

; tell dispatch where to find phtml files
templates = ./views

Headers, Cookies, Session, and Uploads

Get, set headers and cookies via headers() and cookies(), respectively. To access file upload information, use attachment().

# GET a REQUEST header
$token = headers('x-http-token');

# SET a RESPONSE header
headers('x-http-token', 's3cr3t');

# GET a REQUEST cookie value
$name = cookies('name');

# SET a RESPONSE cookie (maps directly to setcookie)
cookies('name', $name, time() + 3500, '/');

# GET a session var
$name = session('name');

# SET a session var
session('name', $name);

# get info about an uploaded file
$upload = attachment('photo');

# get the raw request body as a file
$info = input();
# $info[0] - content type
# $info[1] - path to file containing request body

# get the raw request body
$info = input($load = true);
# $info[0] - content type
# $info[1] - content body (watch out for big uploads)


Other frequently used functionalities wrapped for convenience.

# get client IP
$ip = ip();

# htmlentities() alias
$html = ent($str);

# urlencode alias
$link = url($str);

# print out no-cache headers

# stream back json headers + data

# set response status

# get a hash of empty fields (for forms)
$user = blanks('username', 'email', 'location');

# set a cross-scope value
function foo() {
  stash('name', 'foo');

# get what foo() stored
function bar() {
  $name = stash('name');

URL Rewriting

Dispatch relies on URL rewrites being enabled. Here are some configurations for seting them up on Apache and Nginx.

# apache
<IfModule mod_rewrite.c>
  RewriteEngine on
  # in this case, our app bootstrap file is index.php
  RewriteRule !\.(js|html|ico|gif|jpg|png|css)$ index.php
# nginx
server {
  location = / {
    try_files @site @site;

  location / {
    try_files $uri $uri/ @site;

  #return 404 for all php files as we do have a front controller
  location ~ \.php$ {
    return 404;

  # forward the requests to php-fpm
  location @site {
    fastcgi_pass unix:/var/run/php-fpm/www.sock;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root/index.php;
    #uncomment when running via https
    #fastcgi_param HTTPS on;
