Install php-mcrypt in CentOS 6

php-mcrypt is not in CentOS's standard repositories.  However, it is in Fedora's EPEL repository.

Install the EPEL Repo:
for 32 bit:
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
for 64 bit:
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Then you can
yum install php-mcrypt


EPEL also includes php-mbstring if you need that as i did.
