- First we need to check the current version of PHP. To check the version of PHP run following command:
# php -v

# rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm # rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
For those running on CentOS/RHEL 6:
# rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
- After installing Webtatic yum repository, you need to remove the old version of php-common package. It will also delete it dependencies packages.
# yum remove php-common

# yum install -y php56w php56w-opcache php56w-xml php56w-mcrypt php56w-gd php56w-devel php56w-mysql php56w-intl php56w-mbstring
