Hello,
no problem. I have over 8 years experience as an Linux admin and have done this many times before. I can start now. Please feel free to ask if you have any question. Thank You
I can do this!
keep note: since default path for binary php files used by new version of php and since you asked to do that without of removal of php 5.3, installation of php 5.2 can be made manually only and to different NON DEFAULT location only!
