PHP is not working on Ubuntu Apache server
while you are in ubuntu 17.04
you can follow this steps
sudo apt-get install apache2 php libapache2-mod-php7.0 mysql-server php-mbstring php7.0-mbstring phpmyadmin //install
sudo service apache2 restart //restart
and give it another try for your file(index.php)
Check the below configuration in your web server
sudo apt-get install apache2 php5 libapache2-mod-php5`
It will install everything you need and will start the apache server with support for PHP.
To verify that the php module is loaded, type:
a2query -m php5
if not enabled, then load with:
sudo a2enmod php5
and restart apache:
sudo service apache2 restart
Trying this command actually worked for me
sudo apt-get install php libapache2-mod-php php-mysql php-curl php-gd php-pear php-imagick php-imap php-mcrypt php-recode php-tidy php-xmlrpc
