I want to install the phpmotion on Ubuntu 14.04. I need to use it for php 5.3, and older. I did the PHP installation package but I can not attach extensions. How can I do?
I'm unsure how to get an old copy of PHP 5.3 except from compiling it yourself; it's past end of life so you might be better off finding a newer library than risking the security of your entire application.
The Ondřej Surý PHP 5.4 repo is your best bet to get an older version, though it's one ahead of the version you suggest.
