Problem with mCrypt on CentOS 7

[sagitari.uk]

Hello,

I'm trying to install mCrypt in different ways:
https://www.digitalocean.com/commun...nstall-mcrypt-php-extension-on-centos-7-0-x64

and

http://stackoverflow.com/questions/17109818/install-php-mcrypt-on-centos-6

But no one works for me.

For example:
yum install php-mcrypt*

gave me:

[root@development ~]# yum install php-mcrypt*

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
[root@development ~]#

After:
sudo yum install libmcrypt-devel

I have this:

[root@development ~]# sudo yum install libmcrypt-devel

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:

         1. You have an upgrade for libmcrypt which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libmcrypt of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libmcrypt.otherarch ... this should give you an error
            message showing the root cause of the problem.

         2. You have multiple architectures of libmcrypt installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.

         3. You have duplicate versions of libmcrypt installed already.
            You can use "yum check" to get yum show these errors.

       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).

       Protected multilib versions: libmcrypt-2.5.8-9.el6.i686 != libmcrypt-2.5.8-13.el7.x86_64
[root@development ~]#

I'm confused now.
Will be great if someone could help me with this.

Thank you very much in advance!
