PHP Ubuntu - Dean Verleger

Install PHP

Install PHP and the apache2 php support extension

sudo apt install php libapache2-mod-php

Test:

php -v
save info.php to your webroot (i.e. /var/www/html):
```
<?php
phpinfo();
```
and visit http://localhost/info.php

Install Extensions

In general:

Install Extension, i.e.:
```
sudo apt-get install php-<foo>
```
May not be necessary or trigger loading already loaded extensions. Update php.ini (check location with phpinfo()), i.e.:
```
extension=<foo>
```
(there is a section with many such lines, you may want to uncomment an existing line)
Test by opening up a page containing phpinfo() and locate a section for the module name.

See examples (aka requirements to host kirby cms):

mbstring

```
sudo apt-get install php-mbstring
