Well, I'm trying to gzdeflate my code to perform some very low level encryption for distribution, to use with eval(gzinflate('deflated_code'));

However whenever I try to inflate the deflated string, it outputs an error.

For example:

echo(gzdeflate('test')); outputs +I-.?

But when I try to echo(gzinflate('+I-.?')); it only outputs Warning: gzinflate() [function.gzinflate]: data error

Is there something I'm missing? Why is it outputting this error rather than test?
