The EC2 instance I have been given has php7 installed but without mysql and sqlite3 modules thus unable to use.
I tried sudo yum install php-pdo but it gave error:
amzn-main | 2.1 kB 00:00
amzn-updates | 2.5 kB 00:00

You need the php7 packages. php-* currently installs PHP 5.6 extensions, that’s why you get the dependency conflict error
e.g.
yum install php70-pdo
The various MySQL extensions are in the package php70-mysqlnd
