Have you ever used Zendguard for "Zendguard"? About the trial version of the question, know the people over to see
Latest Zendguard 6.0.0. What I want to ask is that if it is a trial version, the trial period is 14 days.
Then the trial version of the encrypted PHP file is not expired after 14 days? 14 days later, prompt for encryption expiration does not work?
------Solution--------------------
No use.
However, according to the General software trial period, should be expired after the software will not be able to use

------Solution--------------------
Generally does not affect the PHP function, so do not have to detect PHP access, increase judgment impact performance, software developers are not so boring it
The direct trial period is over, you can not use the software on the line ...
