amazon ec2 – Dependency issue trying to install php-mbstring on ec2

Questions:

I am trying to install yii2 on my Amazon Linux AMI instance, it requires the php-mbstring extension to work.

When I tried to run sudo yum install php-mbstring it returned this error:

Error: php56-common conflicts with php-common-5.3.29-1.8.amzn1.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Thanks for your time in advance

How to&Answers:

It seems you have php 5.6 installed.
You need to install mbstring for that particular version of php.

Run sudo yum install php56-mbstring

After that it might be a good idea to restart apache (thanks! @hexicle),
using sudo service httpd restart

Answer:

Amazon Linux AMI release 2017.09

sudo yum install php70-mysqlnd
sudo service httpd restart
