Key-based encryption means a key is required for decryption, so neither PHP nor 
a human will be able to decrypt w/o it.  (Short of a brute force attack, 
assuming any of the common, good algorithms (DES, RSA) are used).

My take on the code encryption controversy, such as it is, is that since a 
significanct percentage of consulting customers are dead-beatish (late or no 
pay), anything you can do to create an incentive for eventual payment, such as 
making modification to delivered code v. difficult, is a good thing.  And that's 
just one application for code-encryption technology, so to say it is never 
useful is silly, IMO.
