Precisely. That is why I said it was adminstrative web applications which
typically have far fewer users than web sites.

Wrong again. This is for administrative web applications, the type that were
previously built as desktop applications. Their function is to get data into
and out of a database i.e. CRUD applications), not to serve thousands of
casual vuisitors.

It depends how you go about it. My code generators fulfil the basics, then
the programmer's job is to customise it.

I have never liked any of the code generators I have seen created by others,
but with my general-purpose framework I noticed that a lot of the code that
I was generating by hand followed a familiar pattern. It was then a simple
exercise to write a program to generate this same code on command.
Be aware that I am not attempting to generate *all* the code that an
application will need, just the basics to get it functioning. This takes
all the drudgery out of the job and leaves the programmer to do the
interesting bits.

The very idea of one object per row makes me want to throw up. I have one
object per table, and each object can deal with any number of rows. I don't
use getters and setters to access the columns from any row, I simply input
an array (typically one row from the $_POST array) and output an array which
may contain any number of rows. I find this to be far easier and no less
efficient.

What do you mean *still*? Since I released it I have never closed it down. I
am still working on it and releasing improvements. I am just about to
release some new functionality which will generate more standard code for
each transaction. Watch my website (see link in my signature) for an
announcement.

If you want to build administrative web applications which have a small
number of users, and where development costs are more important than
performance of execution (i.e. developer cycles over cpu cycles) then check
out RADICORE at http://www.radicore.org It is better than Ruby on Rails.

Not a solution, but an idea... the dos chdir comand. Maybe you can run
it from within your script. It tells you the current working directory
and you end up indirectly knowing the location of the php.exe that
you're using.
Unfortunately there's no guarantee that a) the working directory will be
where the PHP binary is, or b) that the binary is called php.exe.

writing an extension to tell you.

Wouldn't it be an easy task of PHP checking the results to see if
file_exists? That would resolve the first part, but it might
indirectly tell you whether you're using php.exe. If the file_exists
fails, then you can probably assume you're using the dll. I know...
a hacked solution, but maybe it will work?

I have just run a phpinfo and ignore_user_abort is indeed defaulting to off.
It's a pretty heavy php-MySQL script. I noticed on scripts without the
MySQL interaction, the server can keep up much better with the forced
refreshes.
Are there any other liming settings I can change?
All the best,
Ryan

Robert,
Thanks for the reply. I can't seem to find ignore_user_abort in my
php.ini. I would like to do it at server level, rather than individual
scripts. Do you know roughly where is it? I think there were some
versions with this missing in the ini, which was later fixed.
I'm guessing that if ignore_user_abort is set to on, this could be the
culprit?
Would simply adding the following to the ini work?:
ignore_user_abort = off
If it's not in your php.ini and not in your source code then it's
already off, unless it's being activated by an http.conf or .htaccess
setting. The default for ignore_user_abort is 0.
What exactly does your script do? It may be possible that whatever task
it is performing prevents PHP from immediately recognizing the user
abort and subsequently terminating.
Cheers,
Rob.

Jon,
Thanks for the reply. Yes, ignore_abort is defaulting to off, as stated
in my other post. We have a Firebox III 1000 firewall on our external,
however this does not have any features like this. I will look into
iptables.
Thanks,
Ryan

Ignore user abort defaults to off, and doesn't necessarily help you if
the clients don't terminate their connections properly, or they're
actually trying to DoS you. I think your best bet is to either use
some lightweight detection in PHP (and maybe send an HTTP error header
if you're getting hit), or better yet, use a firewall if one is
available to prevent the connections from even getting to your
webserver and wasting its resources. (If your server is running on
Linux, iptables should be able to do what you need, and there are more
complicated solutions too.)

It hasn't actually been attempted. However, if a couple of a users were
to hold the refresh, the page generation times would go up ridiculously
and clients would be waiting over 20sec for pages. As mentioned, it's a
very heavy php-mysql script with lots of queries.

How do you consider this a DoS attack? Are you seeing servers
crippled because a user or a couple of users keep hitting the refresh
key? Honestly, it seems extreme. Your server should be able to
handle much higher loads than that, especially when PHP starts caching
pages, etc.. I would start double checking the server config, etc..
Also, if you're really worried about someone "attacking" a site like
this, you could just take advantage of PHP's auto_prepend to
automatically log the IP and a time stamp of each page request... and
if the last page request is within N seconds of the current request,
you just redirect the user to a page that says something like "server
busy, try again in a moment".

I haven't tried it, but perhaps this would work:
apache-1.3: http://dominia.org/djao/limitipconn.html
apache-2.0: http://dominia.org/djao/limitipconn2.html

I see what you're talking about. Does everyone need live data for
each page request? It seems like a great opportunity for data / page
caching. I'm trying to remember the name of the caching tool I used,
but I ran into something similar on one of my websites a few years
ago. Each page was dynamic and the server load was high. I
installed caching and pages would only update occasionally... meaning
that users received pages from the cache, instead of each page
getting processed with each request. You could also try a reverse
proxy with apache to do something similar. The limit IP stuff from
Roman also looks interesting.

Hello,
Having used php for a while now and am fairly competent I was persuaded by a
collegue to look into asp.net. I decided to download the free trial of
VS2005 and start with a few tutorials.
I am very suprised how easy things like user auhtentication and form
validation is. Literally in minutes. Even though I have written a similar
script many times for php there is always some tweeking or modifying
required before it fits the project. The asp object model is far superior,
something that PHP developers can't really argue against.
Now I know asp .net is not ideal for all projects but I am now thinking that
there are some projects that would be suited to the use of .net and the
development time would be greatly reduced. I would like to know
-What is planned for the next version of PHP?
-How many of you use both of the technologies?
-What influences your decision when using either ASP, .NET, or PHP
I know people feel very strongly about PHP, however I don't want to start an
argument, just want a decent discussion,
Regards,
R.

That's a comparision of code you wrote in PHP with code Microsoft
programmers wrote in C#, and has nothing to do with PHP.

It's hard to say either way since you didn't show us your code.
Are you aware that you're comparing libraries, not programming
languages? There's a gazillion authentication libraries written
in PHP to choose from if you can't write one yourself.

That's a bit like saying that apples are better than oranges. PHP and
ASP.NET, while they were designed to server similar, but not identical
purposes, are different tools. PHP is a programming language, but ASP.NET is
a platform, built on the dotNET framework. You could compare something like
CakePHP to ASP.NET, in pretty much the same way as you could compare PHP
itself to C#.
Now I know asp .net is not ideal for all projects but I am now thinking that
there are some projects that would be suited to the use of .net and the

Unless dotNET is a total absolute piece of crap, them I'm sure there are
some things that are better suited to the ASP.NET than to their PHP
counterpart. I suspect this would be mainly things that integrate with other
MS technologies.

Google is good for you.

-How many of you use both of the technologies?

The first thing it would depend on would be whether I wanted a framework or
a programming language. If I wanted a framework I'd go with ( out of the
above choices ) ASP.NET, where as if I wanted a programming language I'd go
for PHP. Given the choice however, I'd go with a PHP based framework for
websites, unless they had to integrate with windos services.
I don't currently know ASP.NET enough to use it for production purposes,
added to the fact that most of our machines are Solaris, and not Windos.
I know people feel very strongly about PHP, however I don't want to start an

You serious? I would never have thought people on the PHP mailing list would
have any interest at all on PHP.

Checkout :
- Zend Studio
- Zend Platform
- Zend Framework
- Dreamweaver
Google search:
- "PHP Framework"
- "PHP library"
Also checkout Ruby on Rails. Last, but not least, search the PHP
mailing list for other available PHP frameworks for leads.
Keep in mind that editors may save you some work, but they often use
a generic approach - bloated code, less efficient code, code that
doesn't meet the specific needs of your project, code that's
difficult to change without fighting the editor, and code that's more
difficult to troubleshoot when you run into problems. Some people
are actually faster when coding manually, but that applies to C# just
as much as it does to PHP.
The asp object model is far superior,
something that PHP developers can't really argue against.
On what basis are you saying one is superior? It sounds like you're
still trying to learn the differences between your options in order
to choose which one to focus on. Please list individual reasons for
the superiority that you're talking about and give people a chance to
provide counter arguments or counter examples. Every language,
development platform, and development library has strengths and
weaknesses.
Now I know asp .net is not ideal for all projects but I am now
thinking that

Sure, but the same thing could be said for PHP and some of it's
available development tools.
I would like to know
-What is planned for the next version of PHP?
In case you're not already checking, you'll have a more balanced
comparison if you also find out what's planned for the next version
of ASP or .NET.
-How many of you use both of the technologies?
I do. It's more expensive. There's a lot more work in applying
updates. There's also a lot more work to stay current with changes
in technology; Jack of all trades, master of none.
-What influences your decision when using either ASP, .NET, or PHP
The individual needs of each project. It's usually best to stick
with whatever the customer is using if they already have a large
investment in a particular technology. However, it is sometimes cost
effective to switch if the customer can afford it - Google "PHP
versus ASP" or "PHP versus .NET" for plenty of examples. Google
"Linux versus Windows"; this ties into the debate. Compare the cost
of hiring developers for each of the technologies. Compare the cost
of hosting on Linux versus hosting on Windows. Compare the security
of IIS versus Apache. And, like someone else mentioned, compare your
value in being able to develop on one platform versus your value in
being able to develop for one server platform versus your value in
being able to develop for all of the server platforms that Apache/PHP
work under. I've seen examples of .NET being implemented under UNIX;
they didn't work all that well from what I saw, but researching this
might also add to your pool of knowledge on which direction to go.

Hello,
Sorry for the newbie question :(
I have this class named "returnConfigParams" that returns an array
called "$values" through a function called "getMySQLParams()".
My question is how to retrieve the values of the array from the file
that calls the class.
I have:
$params_file = New returnConfigParams;
$params_file->getMySQLParams();
print($params_file[0]);
but doesn't work :(
Help me please.
I'm stuck on this for two hours and didn't find nothing on Google that
could help me.
Cheers,

Yes, it returns an array called $values.
My problem is how to access the individual member of the array.

Just like you'd access members of any other array.
$whatever = $params_file->getMySQLParams();
print($whatever[0]);
This is a matter of basic rules of the language. Did you know
most of the grammer is described in the manual?

Sure, i already tried that, but it doesn't works.
All i get is a blank page.
BTW, here is my class:
class returnConfigParams
{
var $a;
var $b;
var $c;
var $d;
function getMySQLParams()
{
include($_SERVER['DOCUMENT_ROOT']."/properties.php");
$values = array(0 => $a, 1 => $b, 2 => $c, 3 => $d);
return($values);
}
}
Cheers,
AR

since you don't say what's in the included file, I'll assume
it's empty. $a will be unset and print($rCP->getMySQLParams())
will print nothing ("").

Of course, the cost of serialization and deserialization is non-
trivial for
any data structure that is of interesting size, and you have to
keep in mind
that if you aren't syncing to the database periodically then you
will end up
with stale data objects. (An issue in any case, but the longer the
object
representing a view of your database exists, the more of a problem it
becomes. YMMV depending on the data you're holding.)
Has anyone done tests on the difference between the value and
performance of serializing data structures versus just pulling the
data from the database?
PHP stores session data in files by default. There's gotta be a
performance hit for the file access. If you store session data in
MySQL, you're still making a DB query. It seems to me that the
performance is almost the same, which means grabbing the current
record ends up better because you avoid stale data. What do you think?
