Hi and welcome,
Ok, you can skip the test phase and go ahead to configure php correctly to load phalcon extension (in the terminal type php -m you will have a list of already loaded modules).
looks like you are running a linux box. Depending on the distribution you use and the php version that is installed, go to /etc/php/php7 or /etc/php5 or something like that (ok, it seems that you have php5)
you should find there a cli (for calling php from the command line. It will be usefull if you plan to use phalcon developer tools) and an apache2 directories.
Once again, depending of your distribution, in each directory,
- you will find a php.ini file. Try to load phalcon from there: at the end of each php.ini put extension=phalcon.so and restart webserver Then see with php -m if phalcon is loaded
- maybe there is also a conf.d directory if solution above didn't work, then create a 60-plphalcon.ini file where you will put extension=phalcon.so in it and restart webserver
