phalconver

phalconver.sh is a helper script for switching between different PHP and Phalcon versions installed on your system. It can switch both CLI PHP , and PHP loaded into your Apache2 web server. It has been tested on Linux Mint 17.1 Rebecca, but should work on Ubuntu and Debian as well.

Installation

sudo cp phalconver.sh /usr/local/bin/phalconver

Install Apache2 + PHP

It is assumed, that you have both Apache2 and PHP installed on your system in standard locations (i.e. you installed them using apt).

sudo apt-get install apache2

It is OK to install multiple PHP versions. For example you may install PHP 5.6:

sudo apt-get install php5.6 php5.6-common php5.6-cli php5.6-dev libapache2-mod-php5.6

and you may also install PHP 7.0:

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.0 php7.0-common php7.0-cli php7.0-dev libapache2-mod-php7.0

Install Phalcon

Phalcon installation instructions are here. Install multiple Phalcon versions one by one. After each installation go to the appropriate PHP extension directory in /usr/lib/php where phalcon.so has just been installed. Rename phalcon.so to include Phalcon version number.

sudo apt-get install php5-phalcon
cd /usr/lib/php/20131226/
sudo mv phalcon.so phalcon.1.3.6.so

Install another Phalcon version and do the similar:

sudo apt-get install php7.0-phalcon
cd /usr/lib/php/20151012/
sudo mv phalcon.so phalcon.3.0.4.so

Each PHP version has different extension directory. They are all in /usr/lib/php. Check this page, column PHP extension.

Setup symlinks to all installed phalcon modules.

cd /usr/lib/php/20131226/
sudo ln -s phalcon.1.3.6.so phalcon.so

You need to repeat this step for every PHP extension directory in which Phalcon is installed.

Finally, configure your PHP to load Phalcon.

sudo phpenmod phalcon
sudo php5enmod phalcon

You may want to check that all PHP versions installed on your system have the Phalcon module activated. Go to /etc/php/X.Y/apache2/conf.d/ and /etc/php/X.Y/cli/conf.d/ and make sure that there is a symlink for phalcon.ini file.
