php版本5.6.4不同5.6

I made a Laravel 5.3 website in PHP version 5.6.4, but my host is only providing 5.6, 5.5 and 7.0. The website I made isn't running on the server. Are these versions so different that it does not support PHP version 5.6 if built in 5.6.4?

Laravel 5.3 version working on apache 5.6 version as well as 5.5 version

Make some changes in your laravel application

1. Change server.php on root to index.php
2. Copy .htaccess file from public folder and put it into root folder

Now run your application with server url

TRY this :-

Try this, in the public/index.php page

error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
ini_set("display_errors", 1);
