kenn:
You could use an array.
$a = array(1000, 2000, 2000, 4000, 5000);
$num_before = count($a);
$num_after = count(array_unique($a));
If two, or more, variables have the same value, variables $num_before
and $num_after will be different.

Actually in this case there is only one possible way it could have
happened. I'll lay it out simply for you if I must, but it's simple
logical progression.

No, it absolutely has a definitive answer.

The basis of your assertion is incorrect. Methinks you're being
presumptuous by declaring check and mate prematurely.

Because obviously, we occasionally wander off topic.
Your php example made your point very well and was within the subject
-- nicely done.
But, you should had given us time to guess without providing an
explanation. Sometimes, less is more.

Hey all,
I have the following in a text field in the database.
'u',0,'account',1
One my dev server if I update this in the database I get
the same string. On my production server I get this:
\'u\',0,\'account\',1
I thought setting magic_quotes=Off would disable this,
but it did not.
Can someone tell me what does this and how to disable it?
Thanks!

It's the slashes that are getting inserted, but as I said

So I don't want to change the code, if I can help it. I
hope there is a setting that will prevent this from
happening.

The ini setting is magic_quotes_gpc (
http://www.php.net/ref.info#ini.magic-quotes-gpc ). If that doesn't work
the it's mostly like an issue in your code, make sure there aren't any
differences.

Yes, it turns out the production server did not have a
php.ini file!!!
I copied the php.ini-recommended file into place, and it
has magic_quotes_gpc off and that did the trick.
Thanks much!

A good thing to use though, is code that will detect if it is turned on.
Something like this
if ( get_magic_quotes_gpc() ) {
$_GET = array_map("stripslashes", $_GET);
$_POST = array_map("stripslashes", $_POST);
$_REQUEST = array_map("stripslashes", $_REQUEST);
}
This way, it doesn't matter what the setting is, it will be corrected if
it is turned on, no matter what.

Just simple Javascript stuff. Just create a large div block that is
absolutely positioned over the top of everything and spans the whole
width/height of the page.
The either use alpha levels or a small 2x2 gif/png image that produces
the greyed out effect
0X
X0
Then draw your login in the middle of your div.
Not PHP, but it does look nice :)

If you also want users to login first, don't do it like this ;)
I'm listening to the song now without logging in, just running this in
the URL bar:
javascript:floatingWindow.hide();
and the login window is gone :)

So is there a proper way to create a modal window inside a browser?

There is no "proper" way. You have various tools to make one with,
namely pretty much all client-side scripting languages that work in
browsers. There are no standards dictating how it should be done, it's
all left up to the developer, there are just 'options' :)
On a sidenote, this has nothing whatsoever to do with PHP, it's
presentation in a client-browser we're looking at.

I asked here because I believe good PHP programmers are usually
well-versed in client-side stuffs. :)

Something like the following:

what i need is that "monday" means "monday this week", regardless of
whether i ask on monday, tuesday, wednesday, thursday, friday,
saturday or sunday.
the way php works now, i have to something like this:
if(date("l") == "monday")
$from = date("Y-m-d"); // if today if monday, just give today's date
else
$from = date("Y-m-d", strtotime("last monday")); // when asking on
tuesday thru sunday
it would be nice if strtotime understood the form "monday this week".

I don't see how you figure "clearly makes a mistake". For instance the
following script illustrates a VERY clear behaviour that doesn't seem
mistaken to me, it seems more like a design choice:
<?php
$days = array
(
'Monday',
'Tuesday',
'Wednesday',
'Thursday',
'Friday',
'Saturday',
'Sunday',
);
foreach( $days as $day )
{
echo date( 'Y-m-d', strtotime( $day ) ).' ('.$day.")\n";
}
?>
You'll notice that it always presents the first such date from TODAY
ONWARDS.
With that in mind it is trivial to get the date YOU want.
Cheers,
Rob.

How big is your project?
If you're talking about a personal visit counter, run away OOP.
If you're talking about a really big project (And yes, CMS _is_ a
big
project), go ahead and use OOP.
OOP is better to mantain... :-)
