Upgrading stunnel and php?

[interbiz]

My server worked fine for years, on CentOS6, PHP5.3.3, stunnel 4.29...
Suddenly, the bank used for some e-commerce processing changed their requirements for their clients and now require >=PHP5.6 and >=stunnel5.06

Due to stability and existing config, I just don't want to stop using CentOS6... but, I was not successfull in updating to newer PHP and stunnel.
As much I can see on unofficial forum boards, some propose webtatic.com upgrade (for PHP)... but, for stunnel I just can't find any solution.

Could someone give some advice? Is there some .rpm available for stunnel I am looking for or should I try to rebuild it from source?
What is best practice for getting PHP5.6 on CentOS6?

You can get PHP 5.6 from IUS:

Upstream (aka Red Hat) way to provide recent version is SCL.
See https://www.softwarecollections.org/en/

As this allow "parallel" installation this is the only "safe" way (base system is not altered).

Else some 3rd party provides more recent PHP stack.
With different name (IUS...) , or with same name (like remi, which is "now" safe as it only replace "php", no other packages)
And with different set of extensions.
