PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/msqli.so'

Question

Looked at all the articles on search for this and no answers that work -- on Ubuntu 16.04 I\'m getting:

PHP Warning:  PHP Startup: Unable to load dynami         


        

Answer 1

It seems that uninstalling all versions of php with

sudo apt-get purge `dpkg -l | grep php | awk '{print $2}' | tr "\n" " "`` 

and only installing the latest version with

apt install php libapache2-mod-php php-mysql php-xml php-soap php-gd php-mbstring

solved the problem for me.
