PHP Licence Software?

Hey all not sure if this is the correct place or not? but i have a very decent piece of software that my friend made for himself before he joined the army and past it over to me, now i know basic php but not enought for this question that i am about to ask.

i would i go abouts creating a licence system that for example lets say i can set 30 day trials and the person has to enter a licence code before proceeding with the script installation etc.. a bit like what modern bill has done, u have to buy a licence and enter it in the install script no licence no script and it terminates

any help would be nice

Try looking at phpaudit.com or sourceguardian.com

ok thanks vivoxia i will try those

I shared the same concern. There are a lot of piracy in software. Is there any protection for PHP/MySQL script other than "encode" method?

Not really and even the encoded method can still be cracked. You can place "call backs" in your script so that sends a request to your site. You can have a database of all legal users and if a request is from a domain that is not listed, have the script display some error and contact the host the pirate is using. You can never make your script impossible to crack, so you have to make it really annoying to crack. Add call backs everywhere. Add links to pages where you can check for the referrers. What I also do is release the initial version to my group of beta testers. Then I fix everything (call this version 1). Then I add the features they wanted (version 2). Then I figure out what else I could add and make version 3....I then release version 1 and begin version 4. By keeping a couple versions ready, I release the next version as soon as the previous version gets pirated (or when it's been enough time). The plan is to make it impossible to for anyone to pirate the current version by always releasing the next version.
