EventHttp::setCallback

<?php
/*
 * Serveur HTTP simple.
 *
 * Pour le tester :
 * 1) Exécutez-le sur le port de votre choix, i.e. :
 * $ php examples/http.php 8010
 * 2) Dans un autre terminal, connectez-vous sur une adresse de ce port
 * et réalisez une requête GET ou POST (les autres sont désactivées ici), i.e.:
 * $ nc -t 127.0.0.1 8010
 * POST /about HTTP/1.0
 * Content-Type: text/plain
 * Content-Length: 4
 * Connection: close
 * (press Enter)
 *
 * Il devrait afficher :
 * a=12
 * HTTP/1.0 200 OK
 * Content-Type: text/html; charset=ISO-8859-1
 * Connection: close
 *
 * 3) Voir ce qu'affiche le serveur sur le précédent terminal.
