ExpressPHP
This framework tries to clone the NodeJS ExpressJS framework writing style. It does not have an event loop, it just mimics the method and helpers names that ExpressJS offers., (*1)
Install
Note: To run ExpressPHP you need PHP >= 7.0 and Apache., (*2)
The preferred installation is using Composer:, (*3)
composer require aeberdinelli/express-php v1.1.0, (*4)
Then, move the .htaccess to the root of your site and you're done:, (*5)
mv vendor/aeberdinelli/express-php/.htaccess ./.htaccess, (*6)
Usage
If you installed using composer, you can just do:, (*7)
get('/', function($req, $res) {
$res->send('hello world!');
});
$express->listen($router);
?>
Routes
Routes are handled using a Router instance, for example:, (*8)
$router = new Router();
$router->get('/', function($req, $res) {
// This will be called when someone goes to the main page using GET method.
});
You can handle post requests as well using post() instead of get(). Same for put() and delete()., (*9)
Route with dynamic parameters
You can route dynamic URL using parameters, for example:, (*10)
$router = new Router();
$router->get('/:something/:else', function($req, $res) {
/**
* Now let's imagine someone enters to URL: /hello/bye, then:
*
* $req->params->something will contain 'hello'
* $req->params->else will contain 'bye'
*/
});
Responses
If you're developing an API for example, you can send json simply doing:, (*11)
$router->post('/', function($req, $res) {
$res->json(array(
'error' => false,
'message' => 'Hello'
));
});
You can also send a custom http response code using:, (*12)
$router->post('/', function($req, $res) {
$res->status(201)->json({
'error' => false,
'message' => 'Created!'
});
});
TIP: There are a few more examples in the index.php file in this repository., (*13)
Static files
If you wish to serve static files (likes images, html only) you can use:, (*14)
// If you visit /static/image.png, this will return the file views/public/image.png
$router->use('/static', $express->static('views/public'));
Template engines
You have avaible Pug (ex Jade) and Mustache. Here's an example:, (*15)
// Configure the engine to Pug
$express->set('view engine','pug');
// Jade was renamed to Pug, but we recognize it ;)
$express->set('view engine','jade');
// Or Mustache
$express->set('view engine','mustache');
// Set the path to the template files
$express->set('views','./views/pug');
// Now you can do something like this
$router->get('/', function($req, $res) {
$res->render('index.jade');
});
// Or this
$router->get('/users/:username', function($req, $res) {
$res->render('index.jade', array(
'name' => $req->params->username
));
// Now in jade, you can use #{name} to get that variable!
});
CSS Precompilers
You can use Less instead of CSS if you want. An example:, (*16)
use \Express\ExpressLess;
/**
* Let's say you have a /less folder on your project
* And you want every request that goes into /css to load the less file within that folder instead
*
* In this example /css/global.css will load the compiled version of /less/global.less
* Same for /css/something.css -> /less/something.less
*/
$less = new ExpressLess($express, array(
'source' => __DIR__.'/less',
'dest' => '/css'
));
// Yes, it's that simple.
Request info
- You have the body of the request in $res->body no matter if you re handling POST or PUT.
- You have the query string under $req->query
- You have the cookies in $req->cookies
- You have all the request headers in $req->headers
