Reverting unpack('C*', “string”)

Question

I would like to know how I can reverse what this unpack function bellow performed. I think the pack function is able to reverse what unpack performed, however I\'m not sure.

Answer 1

You should use call_user_func_array to revert unpack('C*', “string”), like this:

call_user_func_array('pack', array_merge(array('C*'), $array )))
