We have a legacy app running under PHP 5.3.3. (Don't ask.)
I have some 3rd-party code that needs 5.5+. It only needs to run via the command line, so I think it might be possible to simply(?) install 5.5 as a separate executable I can call when needed.
It would be running on Centos servers.
Anyone have any suggestions on the best way to do this, ensuring that the default "php" remains the current 5.3.3 install? (I am not a yum super-user. )
