How to properly install and configure falcon?

Question

linux

Good day good people!
I am deploying the project locally on ubuntu 18. The
technology stack is used: php7, nginx, falcon, mysql
Tell me how to install falcon correctly, it looks like I put it crookedly :(
Attached nginx logs, swears at falcon... There is no information about it in php_info.

Answer 1

For ubuntu14/16, but in theory it should work on newer versions:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get install php7.0-phalcon

Answer 2

Looks like Phalcon just isn't installed. See the output there should be information about the Phalcon extension. To install, follow the instructions on the official website. phpinfo(); exit;

Answer 3

A common mistake is that the phalcon.dll extension itself and the php version do not match.
Check the version itself, and bit depth.
