Re: Determine overhead of PHP script.

It's more of a time-consuming issue rather than memory usage IMHO. However, unless you make several extra database requests, I found that running PHP code is generally rather fast and adding considerable extra code doesn't affect the speed significantly. I must reiterate however that if your templating engine uses a database, that might increase parsing duration considerably. For your own tests, take a look at microtime() on php.net.

Is there a way to determine the overhead or memory usage of a PHP script as it runs? What I'm looking at is say I've got this nice simple script to display info. Now I want to add a database abstraction layer and a template engine. Sure, this makes it easy for me to control changes, but now I'm including a dozen other files that I may only use a percentage of. So, yeah, it's easy to control, but now it may be taking up 10 times as much memory as it was before. So is there a way to see how much memory/overhead a script is taking up after it does all of its includes? Let me know if I need to explain this more. I'm on a windows machine, but any ideas you have are welcome. I'm sure it's more of an OS-type question, though. ---John Holmes.
