More polished version of @duellsy's mod to prompt for confirmation before running Laravel artisan commands on a specific environment (mainly production).

artisan.php

<?php

// Adding this to your app/start/artisan.php file will
// do a quick confirmation that you really do want 
// to run this command when in production environment

if (php_sapi_name() == "cli" &&
	App::environment() == "production")
{

	echo "\033[0;31m\n";

	echo <<<EOF
