note 50058 rejected from function.eval by nlopess

Note Submitter: alan at andaweb dot com ---- Sorry if this not the way this forum should be used. I develop PHP code in my own server and port them out to my customer's server at the end. One obvious problem is source code protection. I am aware of serveral commercial solutions but I just want to try the following method with eval() first. I'd appreciate if anyone would comment on whether this is a feasable route. I intend to use eval() to achieve 'code encryption'. That is, I will 'hide' or 'encrypt' the source code before I deliver it to customer's server. Then, with password or other mechanism, I will de-cipher the code at the run time using eval(). Is there a big issue with this trend, if we are talking about 1,000 php files? Thanks in advance...
