I've had really good experiences with load balancing a large php app
using
windows 2003 NLB (network load balancing) (really, windows, I'm not
kidding :)).
It's available in 2003 server, you just have to turn it on and
configure.
If you're using windows currently I'd give it a shot before
purchasing a dedicated load balancer. There are some nice
ones out there, but the major drawback is redundancy.
If your load balancer goes out, all of your nodes are unavailable,
So, you'd need at least 2 hardware load balancers operating in failover
mode.
If you care nothing about availability and only care about the
performance
then you've got alot of options.
Of course to load balance your app you need to centralize your data
onto a dedicated data server. You'll have to put some thought into your
session issue, and any other data read/written by the app.
good luck,
will

Hi
Does anyone know where i can get some decent gdf fonts for using in the
imageloadfont() function, i have found some on the net but they are all
a bit naf so far. I'm really just looking for something like Arial or
verdana. Im creating pie charts on the fly but at the moment they look
like something that would be produced by a spectrum or commodore 64!
Thanks
Adrian

You've tried *everything* ?
Why do you think it's "wrong"? Did you get an error message of some kind?
What do you see if you echo $query? Are the values of $cat and $id
what you expected?

Apparently, either $cat or $id is not the value you think it is. First, I
would try changing
$result=mysql_query($query);
to read:
$result=mysql_query($query) or die(mysql_error());
This will, no doubt, lend some insight into where your error is.

Alway throw an error when in question
if(!($result = mysql_query($query, $connection))){
echo mysql_error() . "<br>\n";
exit();
}
My bet is that you need to concatenate
$query = "SELECT title FROM " . $cat . " WHERE id = '". $id ."' ";

Jay how come you though concating would give
a different result to interpolation?

up to here I agree with Jay 100%, especially the 'echo' part (also get
familiar with var_dump() and print_r() functions to help debug your problems...
My bet is that you need to concatenate
$query = "SELECT title FROM " . $cat . " WHERE id = '". $id ."' ";
now unless either $cat or $id is actually an object with a 'magic'
__toString() method defined and the engine has been changed to fully/properly
support 'magic' object2string casting I don't agree that concat'ing will help
(even all of what I sAid was true I don't think it would help either),
the reaosn being that AFAICT the following 2 statements leave you with the same
string:
$cat = "mytable";
$id = 1234;
$one = "SELECT title FROM $cat WHERE id='$id'";
$two = "SELECT title FROM ".$cat." WHERE id = '".$id."'";
var_dump( ($one === $two) ); // <-- will show you that this equates to TRUE.

It is not really a different result, it is just something that I am in the
habit of doing. The "concat or not to concat" question has fueled many a
holy war. I concat, others do not. I am used to seeing it and looking for it
in code. Others think that it adds too much junk.

I probably shouldn't have used "bet"...I just should have suggested it.

I see - personally I don't give a **** about this holy war; I use both
pretty interchangably - depends on the context what I think looks neater.
<tangent>
it is my believe the technically this:
echo $a, $b, $c;
is (should be) faster than:
echo $a . $b . $c;
can anyone confirm this to be true?

I still stand by the fact that whether you bet or suggest the OP would end up
with the same broken query string.
now the hint about using ECHO .. that you could have written in 40 foot high
letters :-)

Google is your friend...

And, by the way, if you are uploading and storing images in your MySQL
DB, you might want to consider that there is a much better database for
storing files. It's called 'filesystem'.
HTH, cheers

I found my problem...I was using:
pspell_new("en", "british");
pspell_new("en", "american");
pspell_new("en", "canadian");
and I should've been using:
pspell_new("en_GB", "british");
pspell_new("en_US", "american");
pspell_new("en_CA", "canadian");
if I want to use specific dictionaries in the english language. There is no
sign of this in the documentation; I stumbled upon this by chance...trying
everything to resolve my problem.
Take care...
Adam.

I found one set of links that might prove helpful: http://
www.helpdesk.com/software-helpdesk.htm A lot of the software doubles
as asset management software or comes bundled with such a module.
There are a yitload of links on that page. I'm only on the Bs. Good
luck.

There are some nice PHP ones out there, but I don't have any

with them:
ruQueue: http://freshmeat.net/projects/ruqueue/

Help Desk Software: http://www.helpdeskreloaded.com/
I'm sure there are more..
At the risk of hijacking this thread, I was hoping to see, in the
answers to Daniel's question, software that handled software/hardware
itinerary and problem history .. so support, but for a closed group of
users, rather like a medical history for each machine and user. Anyone
know of anything like that?

Has anyone seen such a thing? I'm looking to be able to generate web
page previews dynamically and automatically, so I need to render the
page on the server. The most efficient way would be if there was a
PHP HTML rendering extension - gecko or KHTML perhaps. HTML2PDF
doesn't go nearly far enough. Alternatively something like a CLI
option to firefox to run without X (i.e. no visible windows) and
output to a file instead of a display device. The options here don't
indicate that it can do that:

Any other ideas?
