Does this help?
Looks like you need something like that:
$pages = array(
// list of modules you have, for example:
'about' , 'help', etc
);
$page = isset($_GET['page']) isset($pages[$_GET['page']]) ?
$_GET['page'] : 'about';
// about is default page here
then just:
include 'modules/'.$page.'.php';
Always remember that you have to check what is included.
Best approach(if possible) to have a predefined list of all modules which
can be included.
Else, there is some nasty things like:
?page=../index.php
(infinity recurssion)
?page=http://otherhost.com/hacker.
(inclusion of malicious script)
and so on.

All my links are displaying the current page state, and links are not

pass a variable to itself to place into $thisPage using

The sorts of questions I am interested in are: 1. I have a highly variable program which always shows the same page, but which includes different modules to give different results. The various modules call on different functions. Is it better to minimise memory by including only the functions actually required, but increase the number of files included, or to bundle all the functions into one file, thereby reducing the number of files included but increasing the size in memory? 2. As PHP is an interpreted program comments certainly increase the memory requirements, and presumably they slow down the operation of the program. Would stripping out the comments before uploading the production version give any visible improvement in performance? I think, first question you should answer following questions: 1. How large is your workload ? 2. How it is easier to develop this program? 3. can you logically split functions to different modules ? 4. Did you used other methods of optimizations ? This questions is important because: 1. if you don't have huge workload - this kind of optimization won't help you at all. just will take time needed for actual divelopment. 2. PHP Compiler are already fast enough. So if you don't have very high-load website, then it is more important how fast you write program, rather than how many files do you have. 3. If you can logically split them - then it is good to split them, because it will easier to develop them. Mostly, I personally try to separate functions to a modules: I have 2-3 files per action: skin file, and action file. Sometimes: datatype file (for functions related to information type, like Person) Also I have like 10 library files: they have all functions related to this library: skins , person related, etc. This is optimanl, because I can easily find whatever I need when developing. 4. If you have huge load, then it is much more efficient (and easier) to use other methods. For Example: install APC (http://fi2.php.net/apc ) It will cache all requests to your files and this will have huge impact on your performance. Much more than you can achieve by stripping comments on moving functions around. (and it is also very easy to install) Also Memcached Mysql optimization may help a lot. -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You should just benchamrk different approaches :)
btw, not sure that substr will help you a lot:
first you have to get a begining of the time, block, then you have to find
next X chars.
Btw, you can also do it with a quite simple regexp:
preg_match_all('#\[(.{20})#', ..
(where 20 is amount of characters you want to extract.)
or:
preg_match_all('#\[(.{8})(.{12})#', ..
(where 8 is first part of date, and 12 is second part of date.)
But then you will have to parse this string, to convert it to time, which
could take time.
You should just benchmark different approaches, and check which is fastest.
PS: numbers 20,8, 12 are random, just put whtever you need :)
PPS: haven't tested regexps, just check the idea)
I was trying to stay away from regex as much as possible due to the
overhead? I might be wrong here.
This script will be parsing a lot of requests/sec. Thousands, maybe
more, which it also needs to toss into a DB. I want to try and keep it
as fast as possible. This is tricky when you don't know what you are
doing :). My coding is limited to hammering away at the search box on
php.net until I get a push in the right direction. It's just a hack
from there.
Using phpster's substr suggestion has already sped this up considerably.
