Perhaps you weren't aware that every modern database does the same thing (or
can if you turn it on): the results of query sets are cached at the db
server and are available if the same query is used without involving a file
read. If any update changes any of the underlying result sets then the
corresponding cache entry is invalidated and the momeory released for
another cache entry.
Let the db server handle query/cache consistency ... why put yet another
server in the way that will have to be triggered by the underlying db to
clear ITS cache?

Like Hamid Said, if the ColdFusion server has the query already in memory.
It doesn't need to send traffic to another server to get the information
again. Most systems I've worked on have the db and the web server on
different areas of a firewall, so you're going through a lot of excess steps
if you're hitting the db every time for something that won't change.
Plus, you have a granular control on what is being cached. The sql server
will only cache what it has room for. So if enough queries are run against
it, the original query won't be cached anymore regardless.
But I think the original question was about a tree that took a long time to
create, and application variables would be a plus in this situation.....

The problem I have with this is where the database DOES change, and not
on any set interval. I used to work at Insight, and our product
database changed constantly, at any give moment to account for pricing
changes, stock changes, specials, updates from places like TechData,
etc. If I'm caching the results of my query, I miss those updates, and
have a customer placing an order for a product at the wrong price, out
of stock, etc.
Now I can somewhat understand the use of this on a db that rarely
changes, depending on how often rare is. Or in a case where the db is
updated at a set time. Still, if rare is a time period of months, why
have a db anyway? Static HTML would be faster than php, cold fussion,
etc. And if the db is updated at a set time, what happens when I have
to push a change out that is outside of the set time?
Maybe it's just me, but I feel that the db is supposed to handle the
dynamic data, not the web server.

You missed the point. If you have to connect to a server anyway, whjat's
the difference between going to a cached queryset on a CF server or going
to a cached queryset on a db server? It's a wire transaction in any case.

And this won;t happen on the CF server when you run out of memory to cache
a transaction? Yeah, right.
Does CF have to query the db server to stay in sync? Of course it does.
Now there's multiple transactions to coordinate & synchronize.

That remains to be seen. Getting the data in an optimal way can be a
non-trivial operation.

Again, if you're just talking about reading, how hard is it to just do
this to save:
$save_data = '<?php $array = ' . var_export($array) . '; ?>';
Now save that to a RAM disk and include() it whenever you need it
recreated. You can do the same thing with objects, too.

Because most CF servers are installed on the same web server, no wire is
required between the web server and cf server.

You don't have much control over what a db server caches, but considering I
can tell CF exactly what I want it to save the chances are less likely, but
still possible, that it will flush from memory. It's the same with session
variables. I could keep saving data in session variables until I ran out of
memory also.

I'm not talking about queries that require constant refreshing. That would
be a bad use of an application variable. What I'm talking about are queries
that maybe refresh once or twice a day. I can schedule this easily.

I don't have a problem with this method. It would be nice though to be able
just set 1 application variable and be done with it.

This isn't a situation that you would use a cached query. You would only use
it when something doesn't change that often, or you have control of when it
changes.

My time frame is usually once or twice a day. I've set up admin pages that
will refresh the queries on demand, or the pages themselves update the db
and then refresh the query.

Hell, I have stuff like that - it's called generate an include file with a
cron job. Trivial. All my web pages include it. The variables are all set by
an outside process.
Re CF server & Web server. It's "on the wire" (using sockets). You're going
up & down the stacks just as if you're using a wire except for the last 2
levels (ip & above stacks are used).
And only the smallest shops would consider having a web server and CF (or
db) server on the same box. No scalability or easy recovery from failure.
Heck, I run a tiny little ISP out of my basement, and have all major
services segregated onto different machinery with 1000baseT private net
between the different boxes (db & search services, DNS resolvers, web
servers, mail server, and backup array).

Very true, but tests I've done in the past with PostgreSQL and
MySQL-driven PHP sites show that adding a simple static file cache (for
data that changes rarely) can make a world of difference on a
heavily-loaded site, trimming response times by 90% in some cases.
A database server by nature must assume that all data is equally mutable.
An application developer, however, knows by design how "fresh" any one
piece of data needs to be and can cache accordingly. E.g., don't hit the
database for your site's navigational structure or news articles every
single time, if these things don't change more than a few times per week.

This is incorrect. The recommended Web architecture for ColdFusion is to
have the Web server and the CF server on the same physical box and to have
many of these nodes running on small servers.
As for the ColdFusion versus PHP discussion, I'm not really interested.

His case fell apart the moment he admitted that that was the reason he

His motivation was clearly to cash in on either the similarity or the

My server runs Apache 2.0. I am trying to do a simple URL rewrite so that
old URLs will map to our new style of URLS...
From This: articles.php?id=999
To This: articles/999
In the .htaccess file for the htdocs folder that contains the web files, I
put the following:
RewriteEngine on
RewriteRule ^articles\.php\?id=([0-9]+)$ articles/$1 [R]
I've also tried this (no slash in front of ?):
RewriteEngine on
RewriteRule ^articles\.php?id=([0-9]+)$ articles/$1 [R]
But I keep getting a 404 error for articles.php, which means that something
must be wrong with my RewriteRule because it's not matching. I've tried
various tweaks and just can't get it to work.
What am I doing wrong??

I suspect you may not be looking at the problem the right way.
What exactly do you want to do?
Normally, you'd go the other direction; that is, you'd have mod_rewrite
recognize ^/articles/([0-9]+)$ and translate it to /articles.php?id=$1
... so that a request to the "pretty" URL gets served as an HTTP GET on
the PHP script.
I get the impression that you're expecting mod_rewrite to translate copy
from inside your HTML files, as well as recognize and reverse the
translation when the request comes back in. Is that it?

I bet if you create an "articles" directory in your documentroot, with
with files named things like "999" in it, you'll stop seeing the 404's.
Check your apache error_log.
If what you're trying to achieve is to have existing HTML files get
their embedded URLs translated, you're going to have to do that with an
output filter. You can do it with PHP, or use mod_sed ... lots of
options. But a rewrite rule won't change page content, it'll only
rewrite the *requests* that come in.
Of course, if you know all this already, and really are trying to point
requests for /articles.php?id=123 to a file named "123" in the directory
"articles", then you'll still need to inspect your error_log.

A common misconception is that templates provide complete separation
from logic, this is untrue. Template frameworks (the best ones) provide
separation of business logic from presentation logic. So using an "if"
statement inside a template is completely normal if it pertains to the
display logic. So for instance the following is generally valid in a
template (using InterJinn's syntax since I'm writing this :):
<jinn:if name="userSummary" test="{jinn:getValue name=loginStatus}">
<p class="userSummary"> Display information about the user in
some template formatted fashion that will only be displayed if
the user is logged in.</p>
</jinn:if>
Whereas something like the following would not be appropriate template
logic:
<notjinn:setValue name="timeLeft" expr="($age + 3) / 2" />
<jinn:echo value="{jinn:getValue name=timeLeft}" />
Since th calculation for timeLeft would almost certainly be business
logic.
HTH,
Rob.

No (and .exe is a convention that isn't universal, btw). PHP is an
interpreted language, not a compiled one.

Not recommended for production boxes, but...

Also, there's Pharrot, but I don't know if that's even past the planning
stages.
If you're after encoding, try Turck MMCache. It's stable, IIRC.

A while ago there was someone who announced a link to some program that
allowed you to make exe's (yes, it works)... Although, it's 100% uncompiled
(not even to bytecodes), so the only thing you gain is that it'll be easier
to run... :p

Thanks for any advice.
If I register a session variable, set its value with one form and then try
to change its value with another form, it seems to retain only the original
value and is not replaced with the newly posted one?
Is this how it is supposed to work and I have to unset the variable to do
this?

Please include some *concise* code illustrating your problem.

OK thanks. I figured out my problem but I am not sure why this is.
I am trying to impliment a back button to allow the user to go back and
change form values.
If I uses sessions and register $test then this does not work, it sticks
does not change the value of $test if the user re-submits:
<input name="test" type="text" value="<?php echo $test;?>"/>
Thanks for any help!

Hi,
This may be completely crazy, but let me tell you what I want to do:
thread PHP.
My server is a dual-processor 2 GHz machine, and it's not very loaded.
I have a few tasks that are huge and lengthy and would benefit from
being placed in their own "thread" if you will. This would serve to
either accelerate the process by splitting it among CPUs or allow the
process to continue "in the background" for a few seconds after all
pages have been loaded.
There are two areas where I'd use this:
1) To accelerate results in a relevancy ranking/fuzzy matching
algorithm I have created, and although I've optimized the heck out of
it, it can be slow when hundreds of thousands of items are thrown at
it. It would be easy to split the array in half and run the algorithm
on both halves, which would almost half processing time for returning
results.
2) With image processing. When a user uploads an image to a few of my
pages, the image is processed, re-compressed, and filed in the database
or a file system. This can take several seconds, and I'd prefer that
the user doesn't have to wait for the process to complete.
How might I be able to make some PHP code run as a "thread" that would
serve these purposes?

One possibility is to have the code which first receives the request
split it up into subrequests and do HTTP requests for the subrequests.
Whether that makes sense depends on whether the overhead of an HTTP
transaction is a big part of the execution time of the subrequests.

Can you set processor affinity on your system? If so, you can "pseudo
thread" by assigning processes to different CPUs; e.g., run your main
Webserver on one processor and a slave Web server or helper processes
assigned to the other processor. This is a very common way of dividing
tasks on multi-processor systems where code-rewrites to make things
thread-safe are not cost effective.

If you use PHP as an Apache module, you can use Apache 2, which has
threading. Just make sure any extension you use is thread-safe.

Actually, it would work. Just make tree a PHP script, and add something
like this to your .htaccess:
<Files tree>
ForceType application/x-httpd-php
</Files>
Hope that helps.

Hi,
I have been following the thread "Can we make .exe programs with php? " for
some time now and have been visiting the
URLs and examples that are being recomended to do this. Some of the
solutions are pretty good like
BinaryPHP and BCompiler...and I personally use Turck MMCache on our sites.
Am just curious to know what do you guys use when you dont want anybody to
be able to read your
source files...I like the Turck encoder but problem is that the client has
to have Turck installed on his
server to use the files..BCompiler seems good but is still too young, and I
dont know or have a C++
compiler to use BinaryPHP so I use codesecure instead...till now no
problems...but not as secure
(i think) as the others.
The others that come to mind are Zend and Ioncube...too expensive for me
(and quite a few here) , as
I was not born with a silver spoon up my ...or anywhere else.
Since PHP does not have any built in functions to do this, like for example
C...any ideas? or
recomendations?
Thanks,
-Ryan
