first need ya sorry bad english hope u can me strangers. have created domian in linux debian 8.

<virtualhost *:80>  serveradmin admin@admin.com   documentroot "/var/www/saci" servername saci.com serveralias www.saci.com  errorlog ${apache_log_dir}/error.log customlog ${apache_log_dir}/access.log combined   <directory "/var/www/saci">     options indexes followsymlinks multiviews     allowoverride     order allow,deny     allow </directory> </virtualhost> 

i'm using slim , i've created folder named 'app' on folder 'saci' file start.php got this:

<?php  use slim\app;  session_cache_limiter(false); session_start();  ini_set('display_errors', 'on');  define('inc_root', dirname(__dir__));  require inc_root . '/vendor/autoload.php';  $app = new app();  $app->get('/test', function() { echo "this test."; });  ?> 

now on folder saci i've created folder named public 1 index.php , 1 .htaccess. roots

var > www > saci > public

index.php <------------------index daaa

.htaccess <------------------.htaccess
