Is it possible to make a php Cms needed to put some password to install?

Just like we need serial key while installing software, I would like to know if its possible to to make the need to type certain key to install script on web server?

SPBAS and [URL=“”]WHMCS are two examples of software used to create license keys for web-based applications.

I’ve been using WHMCS to create license keys for my own PHP scripts for over a year, it works pretty well. I’ve never tried SPBAS. There are others out there as well. You should take some time to research different software before choosing.

I think this gonna help

and you will need to encode the source code (or part of it) with something like Ion Cube or Zend Encoder to avoid your users just turning off the validity check in the code.
