PHP doesn't work.
Development environment is the below.
- EC2 Server
 - Apache/2.4.7
 - PHP 5.5.9-1ubuntu4.9
 
If I set DocumentRoot /var/www/html, php works well.
On the other hand if I set /home/ubuntu/public_html, php doesn't work, but html works.
$ vi /etc/apache2/sites-available/000-default.conf
    ServerAdmin webmaster@localhost
    DocumentRoot /home/ubuntu/public_html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
				
                        
I resolved it by the below method.
sudo vi /etc/apache2/mods-enabled/php5.conf
