Secure case of PHP Web Applications I'm talking about securities about securities because PHP is open source and you have built an application using this language. you kept it on server and working on over client systems. But when your agreement was terminated wit your hosting provider and lost your all project codes and hosting provider again use same project with no considering you. is there any security for developer, where as he/she can protect their project and skill, can we encrypt to protect applications?
You can use a source code protection program like zend guardian or ioncube. If the former host is using your code, you can sue them. Just because they terminate a contract does not ever give them the right to use your code / content / anything else without permission.
