Hello,
I've recently started PHP development after a few years of working with ASP.
So far I really like PHP, but am having trouble using some of the techniques
I had in ASP. For example, I really like using ASP's Application object to
cache data in, but I can't seem to have an equivalent in PHP.
(Due note that I'm also new to the Unix/Linux environment, so if I have any
concepts glaringly wrong, please correct me).
I've read over the System V shared memory functions, but I can't tell if
these would accomplish what I'm looking to do?
I guess what I really need to learn is how threading and synchronization
works in Apache/PHP. I had just mastered COM/ASP's
single-thread/multi-threaded design and could write shared, multi-threaded
ATL components that all the ASP pages could read from marshalling and all
that.
Are there any good resources/docs on the type of architecture PHP uses and
how to accomplish the above in the Apache/PHP environment? I've looked
around at some books, but all I can find is basic
here's-how-to-do-a-web-page type stuff.
Ideally what I'd like would be an object that would stay loaded in memory
(in-process) so that PHP scripts could call functions and variables against
it with minimal overhead (specifically an object that could cache query
results instead of each page requerying the database). Is such a thing
possible? Or do I have to move over to Servlets/JSP to find this
functionality?
Thanks!
- Stephen
