On the Internet to find all the wrong, the above affixed to this seems to be due to the PHP version of the problem test also has a variety of errors, do not know how to change.

php5.6.3 through
is said to be Java-compatible

You have deprecated:function MCRYPT_CBC () is Deprecated
It's obviously not going to work.
