Slim 3 Middleware Execution Order Example (last in, first executed)

life.md

<?php

require 'vendor/autoload.php';

$app = new \Slim\App();

// Executed last as it's first in (FILE)
$app->add(function ($request, $response, $next) {
	// Execute the routes first
	$response = $next($request, $response);
	// Append the result from routes
	$response->getBody()->write(' Baz ');

	return $response;
});

$app->get('/', function ($req, $res, $args) {
	echo ' Bar ';
});

// Executed first as it's last in (LIFE)
$app->add(function ($request, $response, $next) {
	$response->getBody()->write(' Foo ');

	return $next($request, $response);
});

$app->run();

Oh, I thought there was something wrong with my middlewares. it's executed in an ascending order.

Good example. It's not immediately obvious from the Slim docs on how the sequence of the middlewares is handled.

Great explanation, thank you

Thanks, was very useful explanation!
