Rétrécissement des maillons sans graisse (F3)



Ce n'est pas dommage de raccourcir les liens à 13, non? Un débutant, et pas seulement un débutant, devrait essayer d'écrire votre propre Link Tamer tout en apprenant un nouveau framework. C'est ce que j'ai fait. Que puis-je dire - le cinquiÚme bootstrap, un cadre sans gras et un morceau d'ùme.



Voici le code . Pour les lecteurs comme moi;)



Un cadre, non?



Laravel — 65- FatFreeFramework. Python Flask, , - :



#  
@app.route('/')
def hello_world():
    return 'Hello, World!'





//  
$f3->route('GET /',
    function() {
        echo 'Hello, world!';
    }
);


, . .zip ., , . index.php /ui.



— ui , — , URL.



"":



<?php
//: index.php

// Kickstart the framework
$f3=require('lib/base.php');
$f3->set('DEBUG', 1);
if ((float)PCRE_VERSION<8.0)
    trigger_error('PCRE version is out of date');
$f3->config('config.ini');

//     

$f3->run();
