Chapter 2: Initial container build/run shows PHP warning in browser
When the chapter2 container is initially built and ran, the counter.txt file does not exist. A warning message is displayed in the browser:
The empty counter.txt file needs to be created prior to file_get_contents() from being called in order to resolve the warning.
Resolved on PR #92
Chapter 2: error on build.sh
Running build.sh, I get the following error:

#12 0.623 Enabling module userdir.
#12 0.626 To activate the new configuration, you need to run:

#12 0.652 ERROR: Module php7.3 does not exist!
------
executor failed running [/bin/sh -c a2enmod userdir && a2enmod php7.3]: exit code: 1
It seems that the step number 8 fails because of missing PHP, even if it seems to be installed at step 2.
Do I miss anything?
