helloo..

there is a software which uses licensing scheme to restricr the user.
all the things (the php codes, the licensing server) are with any organization.
the php page checks the license from the licensing server and do accodingly

Now since the php page is a text file with the organization, so they may change the conditional statement in php to allow more people to work on that software

Is there any way to prevent this.

Try hosting the code you need secured on a secure server outside the organization and have your PHP scripts or other software inside the organization call on these scripts.

Or else you could build a mini web-server executable that accepts some input and outputs accordingly. You can build this using sockets, not that hard.


Cheers,

Changed thread title to better match contents.

Have you tried using Zend Guard?

You could also try obfuscating your license file (such as using str_rot13). But that will only discourage casual abuse.
