[PHP] Maximum Execution Time Exceeded

[mikeytf]

I would like to know if you could help me..  I don't understand what is wrong!  
I made a file that is supposed to list 2 categories with the boards that go to 
them under them.  I get a Fatal Error: Maxmimum execution time of 30 seconds 
exceeded.  Here is the file that gives me the error:

Here is the source code for the file:

Thanks.
