Please someone help me!

Hello! First of all, i am trying to solve this problem for more then a week now, i looked through php.net for hours and have posted on numerous boards but nobody could come up and tell me what is going wrong. Basically, i have two multidimensional arrays, and i want to compare those two using array_diff(). The problem is, that the output given is ecxactly the opposite of what i want. To make it easier for those willing to help, i placed the sample code in a textfile so you can view it there. http://www.thebounceroom.com/problem.txt PLEASE, if you have some spare time have a look and tell me why this is not working as it should, as by now i am really frustrated, ive lost a whole week by now and everybody else has to wait just because of me. Thanks a lot in advance for your time reading this! With best regards from Vienna, Jürgen
