Trying to install PHP 7 now that it's available;

(on centos 7)

added repo's:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Then installed via:

yum install php70w php70w-opcache

Error: php70w-common conflicts with php-common-5.4.16-36.el7_1.x86_64
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

So the problem is : Error: php70w-common conflicts with php-common-5.4.16-36.el7_1.x86_64

How to fix this? I need both versions running simultaneously.
