Switch php versions on commandline ubuntu 16.04
I have installed php 5.6 and and php 7.1 on my Ubuntu 16.04
I know with Apache as my web server, I can do
a2enmod php5.6 #to enable php5
a2enmod php7.1 #to enable php7
When I disable php7.1 in Apache modules and enable php 5.6, Apache recognizes the change and uses php 5.6 interpreter as expected.
But when I run internal php web server from the commandline:
php -S localhost:8888
php handles requests using php 7. So how do I switch between php 5.6 and php 7.1 in the command line ?
