PHP is included in many common Linux and Unix distributions. If it is not installed, it is best to install PHP on your system using the package manager, for example:
sudo apt install php php-odbc
sudo apt install php-fpm
To configure FastCGI, type the following command (this example uses the nano text editor):
sudo nano /etc/php/7.0/fpm/php.ini
Edit the php.ini file to find:
cgi.fix_pathinfo
And set it to:
cgi.fix_pathinfo=0
To restart the service:
sudo service php7.0-fpm restart
Note: PHP 4, PHP 5, or PHP 7 will work with the FairCom DB ODBC interface. The FairCom DB PHP interface that is integrated with c-tree only supports PHP 5.
