weird isset problem

Hi! I have this weird thing happening here and I just can't see the problem. Can someone look at this and tell me if you see what is wrong? Below is a code snippet I am using and the output from the code. As can be seen in the output all the $config[*] stuff are set. The if statement still gets executed though as if one or more $config[*] isn't set. Inside of the if statement I checked again and sure enough, they are still set even though the program makes it into the if statement. I am so confused. Thanks in advance!
