PHP general list,
This is probably obvious to people who are good at PHP, but I'm
I have a PHP based CMS (content management system) built, which has
grown and become quite robust. It's now spread out over about 30 files,
and each file represents one class within the object oriented design.
Each are a couple hundred lines of code, and two or three of the most
critical classes are over a thousand lines of code.
While first building it, I didn't really anticipate quite that many
files. What I did is have a file called "includes.php", which list all
the files to be included. Then I in turn included "includes.php" at the
beginning of my "index.php" file. Every page request passes through the
"index.php" file, so that basically means every single file is included
at the start of every new page request.
I'm using Zend Studio, which has a "profile" option, which shows how
long it takes for my PHP scripts to complete a request. It has a
breakdown showing percentages of which scripts are using that processing
time.
Currently, my processes are taking under a second, but they can be
around half a second or more. Although it all happens too fast for me to
really notice as a person, it seems to me that a half second of
processing time might be kind of long and lead to scalability problems.
My first question is: Is a half second too long? I'm pretty sure it is,
but maybe I'm just being paranoid. What do people consider to be
acceptable time frames for processing a web page similar to what
Wikipedia delivers?
Most of the time is taken with the includes. Anywhere from 60% to 90% of
the time it takes to process my scripts is coming from the includes.php
file.
I read somewhere that it's not a good idea to have more than 10 includes
in any one place. I'm fine with trying to break up my include requests,
but I'm unsure as to how. As each function in each class passes around
objects, it's not clear from looking at the code which ones are used at
any one time, so I'm unsure how to efficiently include only the
necessary classes.
My second question is: Is there a systematic way of determining how to
incrementally include files that people use? Or is it just a constant
process of testing and checking?
Thank you for any advice.
