installing

Add the extension to your php.ini:

extension=phalcon.so

you can find your php.ini path by searching in phpinfo() output in your browser

<?php
// https://localhost/info.php
phpinfo();

don't forget to restart your webserver after adding extension to your php.ini

did you mean Phalcon commands in terminal (shell) (PHP Client)? or in your webserver?

in terminal like phalcon project test or phalcon commands are not working

....

in your terminal run

php -i | grep php.ini

and find you php client php.ini path then add extension=phalcon.so to this php.ini too like what you did for your webserver php.ini

These php.ini are different. One of them is php configuration for webserver and another one is for php configuration in php-cli (terminal/shell).

php -i | grep php.ini for this commands ..... PHP Warning: Module 'phalcon' already loaded in Unknown on line 0 PHP Warning: Module 'phalcon' already loaded in Unknown on line 0 Configuration File (php.ini) Path => /etc Loaded Configuration File => /private/etc/php.ini

php-cli in terminal commands not found now whats can i do ??

php -i | grep ini Configuration File (php.ini) Path => /etc Loaded Configuration File => /private/etc/php.ini Scan this dir for additional .ini files => (none) Additional .ini files parsed => (none) user_ini.cache_ttl => 300 => 300 user_ini.filename => .user.ini => .user.ini PHP Warning: Unknown: It is not safe to rely on the system's timezone settings.

whats can i do now ??

it seems that you've added extension to ini file before but I don't know why your error didn't give correct path!!! Uknown LINE 0!!!

extension=phalcon.so should be added to "/private/etc/php.ini" or other external ini files in php Path. I use Linux and I have no experience in MAC/Windows. but I thinks you should find where you've added extension=phalcon.so to by using grep -r command. for example see my result in ubunut OS. Where /etc/php5 is my php main configuration path. and my php version is : PHP 5.5.9-1

[email protected]:/etc/php5$ sudo grep -r "phalcon.so" ./
./cli/conf.d/20-phalcon.ini:extension=phalcon.so //php.ini that used for my webserver (Apache) and Ive added Phalcon extension  to it
./mods-available/phalcon.ini:extension=phalcon.so //my compiled Phalcon extension path
./apache2/conf.d/20-phalcon.ini:extension=phalcon.so //php.ini that used for my php-cli and Ive added Phalcon extension to it too

I thinks you have duplicate Phalcon extension add to your PHP configuration. I think removing duplicate add could solve your problem

by the way there is no php-cli command it's "php" command that we call it php-cli(ent) and we run it like: "php -i" or "php --version"

When I install this, does it produce any temp files? where are they written to? Which files can I delete safely? I'm trying to build a docker image, but it looks like it has some kind of files lying around. Anyone know about this?
