PEAR and PECL for additional php versions

[MoritzKK]

I would like to use PEAR and PECL to install some php extensions (e.g. mcrypt, APCu and redis) for each php version separately. How do I use those tools since the additional php versions are located at /opt/plesk/php/5.* and the CentOS 7 managed one is at /etc/php.d/ .

Is it possible to install extensions for all versions in once or do i have to install it separately and how?

kind regards
