I want to add license or code prevention against theifs.
it may not only against to customer, this protection also can be against hosting compainies which are copying code from your hosting account.[/quote]

Just use a decent hosting company and write up an SLA instead of trying to encode it. Firstly, no encoding is foolproof. Secondly, the hosting company probably doesn't care.

Well you can't. Doing more stuff always takes longer.
