write a PHP website for my customer

[perhapscwk]

Hi..

If i write a PHP website to my customer, they have fully access to
their domain.

Then how I can protect my code? If they copy all the file and give it to
someone else, then after some modification, then their friend can use it.

anyway to protect myself?

thanks.

You can obfuscate your code. But the great thing about PHP is: it's open source! You'll never truly protect your code.

The other option is do nothing to the code but in the contract you have with the customer state clearly that any alterations to the code void any support or warranty, whilst issues will be fixed if the cause is found to be the customer tampering with the code charge them more.

It's a non-techy solution but one that the customer will understand from a business point of view.

You can give the your code in encodede format but required to purchase the licence to encode the code.Zend also provide the encoded the code and protect

Heya, perhapscwk.

Look at Zend Guard and Ion Cube. Both will do what you need. They are not free, but I'm assuming your intellectual property isn't, either!
