securing PHP code
<p>I do quite large project for a client and I would like (somehow) to secure code form event that mid dishonest client was not going to pay me for the work. :)
The contract is written that the project must provide application with a sources.
So far I mostly been writing in .NET where I was protecting myself against such an eventuality in way that I was creating class witch get POST some parameters with shutdown application. This class was thrown into a dll witch was already compiled, so no one could change the source.
Is there a similar possibility in PHP? I can do the same thing (as in .NET case) but clever customers with access to PHP can find above class and I just cut it.
Maybe it is some other way to secure myself?
Suturing of the database also eliminated for similar reasons as above.</p>
