I'm looking to move my PHP/MySQL application from my home PC to a web hosting service. Bluehost.com ($100/year) seems to be a popular choice however their servers use different software versions than I'm currently using on my home PC: OS (I'm running XP on my desktop, host runs Linux) Apache (I'm running 2.0.55 on my desktop, host running 1.3.33) PHP (I'm running 5.0 on my desktop, host running 5.0) MySQL (I'm running 5.0.15 on my desktop, host running 4.1.1.4) Is this a major issue? Also, once I get up and running on a hosted server, is it typical to make changes directly on the hosted server or will I need to make changes on my home PC and then port them to the hosted server? Can anyone recommend a good web hosting service? Thanks in advance.
