We are building this online application using MVC approach (but a bit tweeked).
The structure of the application goes like this.
class Page{

The PHP Script runs fine. It takes about 0.03 to load.
But when the script reaches the CalendarExpiryItemList class. It takes about 30 seconds and my server times out.
Each table would have around 12 to 15 fields on an average and about 10 to 100 records to go through.
I am on hosting with a hosting company they have load balancers. So if my scripts takes more than 30 seconds the load balancer resets my connection and return an error saying “Server sent no data”
As the others say you should try profile your code.
…without being able to debug the code, maybe one or more of the methods in CalendarExpiryItemList class is failing at some point either; on the query, or associated query, or returning a endless loop. You should test and debug each method individually on a your test server to see what results your getting. For a quick and dirty test, just log the output of each method to a file. Also check $_SESSION[‘user_id’] has a value and use “. (int) $_SESSION[‘user_id’] as well before sending it the db in case its empty because its not escaped.
