 Is there any way to protect a php program. Like you can other software
 were you can limit the amount of time they can use it. something like a
 compiled c program that the php program would have to look of a cod
 otherwise it will not work. Or am I just dreaming

MaD uhm. open source. you can protect it against the dumbest, but other
MaD than that... make some vital features of it dependend on a server that
MaD operates only when it receives a unique serial (md5sum) in the
MaD request, which you can check againsta a database of expiration
MaD dates...

MaD obfuscation/encryption may also work, but that's crackable. or you
MaD provide a vital part as executable that you system() from the
MaD script...

Essentially, it means making the code hard to read, follow and locate.

 encryption

It's the coding or scrambling of data that requires decoding to be read.
MaD dUCK's other suggestions are better since he is correct in saying these
methods aren't the best.  An analogy is like leaving a bike unattended on a
crowded city street, but typing it up in string.  Anyone with time and half
a clue can ride the bike away.  The Zend compiler is worth looking at.
