upgrade php to 5.5.3 on centos

I hope to upgrade php to PHP 5.4.19
and the php verison that was installed with virtualmin is
PHP 5.3.3 (cli) (built: Jul 12 2013 20:35:47)

Can I upgrade via console command?
or have to upgrade via virtualmin interface?

Your comment welcome

Howdy,

That PHP version is the package provided by RHEL/CentOS… that contains a number of bugfixes and security fixes, as they backport those into their PHP version.

However, if you wanted to use a newer PHP version – while there isn’t a supported way to upgrade the standard version, there is a way to run two PHP versions, as described here:
