I'm not dividing them into groups of 20.
I'm taking the min/max of the top 100, and dividing the SCALE into 5
equal chunks.
The scores themselves are weighted already, with only one or two in
the top 1/5th, a handful in the 2nd 1/5th, a goodly number in the 3rd
1/5th, a lot in the 4th 1/5th, and a buttload are down in that last
1/5th.
In other words, I took the Top 100, and graphed them on normal
cartesian graph paper -- What I was originally trying to do was graph
them on logarithmic paper.

If I took the first 20, second 20, etc, yeah, that would be way wrong
as well.
I didn't do that.
I just scaled my "grid" upon which to graph them in cartesian space at
an offset of MIN(top100) - MAX(top100) and then let the chips fall
where they may on graphing.
> Do you see what I mean?
Yes -- I think we ended up with pretty much the same result...
Well, not the *same*, but very similar shaped curves anyway.
But my way was "easier" as I just let the natural distribution of the
data on standard graph paper take care of distributing the points
where they belonged.
I suppose there is some merit to forcing the Standard Distribution
instead of living with whatever the "real" data is.
But I'm more happy living with the Reality of the data than applying a
Standard Distribution to data which, according to some experts, isn't
even a Standard Distribution at all, but a "long tail" or some other
terms they bandy about that mean the same thing as "long tail" as I
understand it...
I don't claim my way is "right" -- just that it "works" and is dead
easy and is data-driven rather than conforming to some statistical
model which may or may not be the correct model in the first place.
If somebody NEEDS a Standard Distribution, for sure use Tedd's stuff,
cuz that is what that is.
If you're just trying to "graph" the data that have, whatever it may
be, just graph it, scaled and offset, and see what kind of curve you
have.

No.
You'll just get "Array" back.
You can do a few things:
<?php
foreach($attend_ary_save as $k1 => $v1){
foreach($v1 as $k2 => $v2){
?><input type="hidden" name="attend_ary_save[<?php echo
$k1?>][<?php echo $k2?>]" value="<?php echo $v2?>" /><?php
}
}
?>
Actually, you should wrap htmlentities() around each value being
echo-ed out.
Another option is to http://php.net/serialize the data before you send
it to HTML, and then (duh) unserialize it when it comes back.
Or, be REALLY smart, and use session_start() and just put the array in
$_SESSION and don't send data back-n-forth over HTTP, which is A)
expensive, and B) subject to user tampering, and C) inefficient.
Actually, A and C technically depend on your bandwidth versus hard
drive speed, or wherever you store you session data, so, in theory, it
could be cheaper or more efficient to use HTTP... But I sure doubt it
in any real world hardware setup.
PS Just FYI, internally, PHP's session data is just serialized the
same way you'd do it for HTTP.

Seems like you're right, but maybe I'm also missing something.

Perhaps the if (function_exists()) business is trying to be "smart"
and is run because at the time it was compiled, the function didn't
exist, so you could define the function there -- which is a much more
common idiom than what you are doing, truth to tell...

Richard,
Neither removing the if/else nor the function_exists() not call worked.
If I declared the function in the same file I called it works even
when defining it after the call.
If the function is declaring in a different file than the one I call
it in and I include the files after the call, it simply doesn't work.
Unless I did something subtly wrong or am back on the drugs.
This SEEMS contrary to the documentation.
The "issue" occurs in PHP-CLI 4.4.4, PHP 5.2.1, and PHP 5.2.2.
I'll files a bug report in the hope of an explanation but I'm pretty
sure that it isn't considered a bug.

It's not contrary to the documentation. The docs say that a function
does not need to be declared before use - this is true, so long as it's
declared in the same file.
When PHP parses a file it first looks through it looking for
declarations and adds them to the global scope. It then goes through it
again executing the code. Require/include and their _once versions don't
get executed until the second pass, and they get done at the point where
they're called.
So, if you're going to use functions in an included file, you need to
include that file before trying to use them. If you're using functions
in the same file, the order of things in that file does not matter.
This is *not* a bug!!
Hope that clears it up.

Use name="attend[<?php echo $user_id?>]"
This will simplify life immensely on the processing side where you can
just iterate through $_POST['attend'] as an array and have the
$user_id.
Ditto for the pay[<?php echo $user_id?>] and other fields.
Note that the checkboxes will ONLY send in keys/values for the checked
ones -- You get nothing for the unchecked ones -- which is fine, you
assume they weren't there if they weren't checked.

Use self:: only when you don't have an actual instance handy, is a
general rule, I think...
self:: is kinda like using the Plato-like "ideal" of the class --
there's no actual instantiated real-world "thing" to work on.
You're working with an abstract non-existant idealized non-object.
$x (or $this) you are working with an actual real-life instantiated
"object".
Disclaimer:
This is how I thought of it in C++, rather than a ton of experience in
PHP...
PS
PHP 6 may become more "strict" about using / not using self:: where it
"should" be used... Depends on how the Internals 'discussions' pan
out...

On Windows, assuming you have the dbase DLL matching your PHP version
in the extensions directory, that's almost all there is to enabling
dbase, I presume -- that's how all the other extensions work...
You also have to re-start Apache, or IIS, or the whole machine,
depending on what you are running and how MS feels that day.

Can you export dbf to something like CSV or tab-delimited?
There are usually stock tools for that, which are efficient and
well-tested.
Importing a CSV or tab-delimited is also stock/easy/efficient/robust.

You really really shouldn't be using an ID field for any kind of
"order" involving next/prev... It's just a Bad Idea from the
get-go...
An ID is supposed to be more abstract than that, really.
That said, the IDs in MOST dbs *are* in order, and you *can* just
write a query using the result from the one you already have with <
and get the previous, and another query with > to get the next. Limit
1 on both queries.

Errr.
To be pedantic, I don't think "most" sites require registration,
actually... :-)
I'm not saying it's "bad" or anything, just that there's still way
more HTML pages out there with free access and no registration than
pages that require registration -- and I do think that fact that
there's more "free" stuff than "requires registration" stuff is a very
good thing, on the whole.

Well...
It has to be accessible from *SOME* htdocs tree *somewhere*.
Doesn't *have* to be the same doctree, nor even the same server.
Though the browser might warn the user that you're maybe trying to
"fool" them if the feeds don't all come from the same domain, and if
you don't jump through Javascript hoops to explicitly allow yourself
to use multiple domains...

Yes.
Or it could be POST, I presume, if you wanted.
Technically, I suppose it could even be HEAD or PUT or something even
more esoteric...

You don't HAVE to return actual JS code.
You could return XML and have JS process the XML.
Or there's some nifty JSON data form expressly made-up for AJAX, as I
understand it.
http://php.net/json

Well, you definitely won't protect it at all if it's "out there"
without requiring the login, so don't do that.
Require the login, then figure out how to get the JS to be
authenticated, without exposing the user's password in the process.

Sure. But then your JS has to be ready to send the cookies and all
that...
I presume that's the grunge stuff the AJAX framework thingies handle
for you.
Or you can find JS code to do it in seconds of googling.
It's not exactly rocket science.
AJAX is just like curl, only not, and on the browser side from
JavaScript instead of server-side from PHP, if that helps. :-)

How secure is "secure enough"?
Are you passing around financial instruments -- actual money?
Is it medical data?
Confidential peronsal information?
Super-expensive subscription data worth thousands of dollars?
Nobody can answer this for you until you explicitly state just how
secure is secure enough, and for all of the above, the answer might be
"just don't do that"...
If it's not *that* sensitive, then a standard cookie session should be
enough for *most* uses.
Maybe you'll want to use SSL to protect the data in transit.

The AJAX thingies I've seen are using XmlHttpRequest object, which is
*expecting* an HTTP response...
So it's expecting the usual headers you're thinking of.
So if you don't have them, or at least some of them, it most likely
won't work at all.
Whether it will handle the cookies or HTTP Basic Auth properly or not
is up the the AJAX framework or your XmlHttpRequest-handling code...
You either send the cookies or Auth credentials, or it won't work.

Do the SQL injection defense FIRST.
Do the login screen SECOND.

Writing it backwards from that is just too risky.

It's fine so far, as a start.
You can quibble over using different ways to get all those variables,
but you haven't messed up yet.
Except for not calling http://php.net/htmlentities on all the data you
send to the browser, in case, say, $Add1 contains "Main & State".

If you can find users dumb enough to download and execute a .bat file
from your site, that .bat file can do *anything* *it* *wants*...
You'll have to ask on some kind of .bat list (or perhaps .bat cave)
how to download a file without prompting, but it's got nothing to do
with PHP at that point...
Good luck!
PS *NOBODY* should be downloading your .bat file and running it in the
first place...

I dunno for sure what empty() is gonna do with $result, but I suspect
that this message should say "query failed" rather than "no data"
No data returned is not an error, it's just an empty set, which is
very common.

It should have solved it, unless you've messed up your session data
with the previous script already...
Are you SURE they turned it OFF? Check phpinfo again.
If all else fails, just change the variable name to something else in
the usr_frm.php script, so they don't "collide" with session data...

Honestly, is really doesn't make a damn bit of difference unless you
have ZILLIONS of records in the first place, in which case you
shouldn't be sucking them all down at once anyway...
So write whatever you can figure out what's going on next month/year
without beating your head against the wall trying to read your own
code.
Worry about optimizing only after you identify bottlenecks.
Anything else is optimize-wankery.

You know more than me daniel :P
All current releases aren't packed with any license, and in
sourceforge the PHP license is selected i believe :P
I'd say, don't worry too much about the license, just put your name on
top of the code, and some other nonsense, like:
You're allowed to use this code, as long as you leave above lines
intact., where above your credit is listed of course.

Oh, wow! That sounds like a great project... and it is cool to hear what

Ah, well, that does sound good too. I a mainly looking to keep my
name/website somewhere in the comments. :D
Whichever route I end-up taking, it is definitely nice to hear what the
pros prefer. ;)
Thanks again Tijnema!
Have a great day.
Cheers,
Micky

Don't forget the MIT license allows people to incorporate your code into
commercial products and sell for profit without having to give anything
back (money/improved code/etc).

Right, I alluded to that, but perhaps I should've said that exactly, as
it may bother some people. In my case, it doesn't bother me in the least,
just as I use LAMP (all open source) to make a living.

I've got a cgi file in my cgi-bin folder that I'm calling with include(). It worked with php4.
My shared host just upgraded to my server to php5.2.0 and the function doesn't work. I can't tell if the problem is a
php5 or server configuration [which may have changed during the upgrade] issue.
If I call the file as a URL directly, it works.
http://www.foo.org/cgi-bin/file.cgi?dir=/test&perms=0755
file.cgi chmods the designated directory's permissions. It's a cgi with a php shebang #!/usr/bin/php
A simple file_exists() shows the file exists OK, TRUE.
I've tried using both syntaxes.
include("/home/foo/public_html/cgi-bin/file.cgi?dir=test&perms=0755");
include("www.foo.org/cgi-bin/file.cgi?dir=test&perms=0755");
Here is the error msg:
> Warning: include(/home/foo/public_html/cgi-bin/file.cgi?dir=/test&perms=0755)
[function.include]: failed to open stream: No such file or directory in /home/foo/public_html/EditPage/cgi_file_test.php
on line 15
Bottom line: It appears include() is not working right, for whatever reason.
Anyone have any ideas?
Thanks, Al........
