php7 on 16.04 not working after reinstall of Apache

Question

I was making changes to Apache and killed the configuration. Apache didn't work. So, I removed it and reinstalled. Apache works. Mysql works. But, the PHP test won't work. The php test file is there in /var/www/html but won't come up. http://localhost/test2.php in the browser just give me an empty screen.

Reinstalling PHP doesn't seem to help. I just get a blank screen without an error message. WordPress doesn't come up either.

Any suggestions?

Can you please [edit] into your question the relevant logs from `/var/log/apache2/error.log`? — Dan, Nov 06 '17 at 10:57
Try to install and enable the php module, restart Apache: `sudo apt install libapache2-mod-php7.0`; `sudo a2enmod php7.0`; `sudo systemctl restart apache2.service`- and try to access your `phpinfo()` page again. — pa4080, Nov 07 '17 at 13:24

Try to install and enable the php module, restart Apache:

sudo apt install libapache2-mod-php7.0  
sudo a2enmod php7.0                     
sudo systemctl restart apache2.service

Then try to access your <?php phpinfo(); ?> page again.

Here is what the above command do:

apt install libapache2-mod-php7.0 - Install the Apache's PHP module for php7.0.
a2enmod php7.0 - Enable the module - this command will create a symbolic link for module's files from /etc/apache2/mods-available to /etc/apache2/mods-enabled.
systemctl restart apache2.service - Restart Apache to accept the new configuration (it can be just reload).

All modules from the directory /etc/apache2/mods-enabled are included within the Apache's main configuration file /etc/apache2/apache2.conf by the directives:
```
IncludeOptional mods-enabled/*.load
IncludeOptional mods-enabled/*.conf
```
