Your problem starts here - file returns the file in an array. Each element
of the array corresponds to a line in the file, with the newline still
attached. When you compare to a string without the newline at the end, the
comparison fails.

If you have php > 5.0.0 you can use the FILE_IGNORE_NEW_LINES flag in the
file() arguments, otherwise use trim() to remove trailing whitespace from
the array elements.

Sorry I re-wrote for problem clarity.

FYI whenever I do a var_dump it always shows $stringOne as being 2 
characters less

e.g.
var_dump($foodlandPA[45]);
var_dump($storeInfo);

string(31) "Wellston Foodland Wellston OH " string(29) "Wellston Foodland 
Wellston OH"

This would be because of the ' ' and "\n" at the end of the 31 char line
use trim to remove the white space before your comparison and it should work.
One other thing I noticed, in your SQL insert statement, are all variables coming from the post? If so, do you need to reference the $_POST['..'] array instead and clean them?? 

or have you already done that?

--- Begin Message --- If you are not able to get anything into your DB (and your connection is ok), then two things might be wrong: your input or the query string itself.
Echo out the query string and try to use the query "manually" (directly with a MySQL client). If the query string is ok, you might check your MySQL connection settings (var_dump, echo etc). If the query string is not ok, you have to look at the input values for the query ($regName, $regAddress etc).

Yes, I think that you can compare it with the Referrer header, it's

that will specify their timezone offset. This way scripts will be able

It's pretty useless and unreliable since user's clocks/timezone
settings are incorrect far too often...
I'm only considering the timezone information. I believe that this is not the proper way to think before making a start. The fact that many user's timezone is incorrect doesn't mean that this is not needed. Lets just hope that one day Windows will do the right thing and keep the time in UTC while displaying it using the appropriate timezone.
Timezone information is only of use for the CURRENT day - even if it is wrong. It is ESSENTIAL that any changes also include the daylight saving information. Since this is not included, all current sites handling event related information in real time need to manually log a users PROPER time and daylight saving information so that they know if 8AM today is the same as 8AM tomorrow.
If this is not going to actually fix the problem - don't bother wasting time on it :)

  Since HTTP is a query and response protocol, timezone information will be 
sent on each query. Lets say that it is XX of month Y 1:59 and that the 
timeoffset is changed at '2:00' by +1. A request  sent at 1:59 will have an 
offset, lets say +0200. A request sent at 3:00 (that's one minute after 1:59) 
will have an offset of +0300. 

  Full timezone information requires a POSIX 1003.1 timezone string that is 
quite complex to parse and support, since the server side script must be able 
to identify all of the available timezones. The first draft proposed this 
representation but was changed after the suggestions of ietf-http-wg mailing 
list people to only include the offset for simplicity.

  Timezone information is not meant to be stored as session information nor 
being used for anything else than one-time time/date representation. It is 
just a way for the client to say: If you're going to show me something that 
is time related then you should know that you should represent it using this 
offset from GMT. Something like the Accepted-Language header.

  Lets say you're viewing an MRTG generated graph. This graph uses the time as 
the X-axis value. Lets say that the server is in Greece where the offset is 
+0200 (+0300 during DST) and that the time is 14:10. The graph will end its X 
axis at the current time (14:10). Someone from the UK visits the graph page 
and he should see the same graph ending in 12:10 (UK is +0000). An incorrect 
timezone string will only result in 'bad' time representation which will be 
the case anyway (without TZ).

  There is no need to include the DST information since when on DST the client 
will be sending the propper offset. For example, EET+2EEST is +0200 during 
winter and +0300 during DST.

  Hope this clears things a bit... 

  By the way, what makes you think that most people have an invalid timezone

Hope this clears things a bit...
As I actually USE a clients time offset, I know what the problem is. The DATA is ALL stored as UTC time data, so it does not matter who enters it. It will be stored without a time offset. When building a calender of events, I need to know the clients daylight saving time - since it is not available in the browser we have to handle it manually anyway so the browser feed is always a waste of time since it simply does not give you any USEFUL information. If I am building a calender of events over a change in daylight saving I NEED to know !!! Now it would be possible to ignore time zone and daylight saving when storing data, but THAT becomes an even worse mess when trying to manage meetings across Europe. They can all be at 9AM but not happening at the same time as you have to track the daylight saving at each location :)
By the way, what makes you think that most people have an invalid timezone configured? Windows XP have NTP support that is enabled by default.

Correct, so people select the timezone that gives the right time, if the daylight saving switch is off. And then the calendar gives the wrong times when trying to display a weekend containing a daylight saving change. ( THAT one wasted a few hours before we twigged what was wrong - since the clock was right :) )

Like if the NTP works :P, when I go to the settings I see that my time
was last synchronised on the date I installed XP, and when I try to
run it manually, both servers fail to update. While i have a 24/7
Internet connection :)
This is the same for all my XPSP2/XPMCE installations. And what does
make you think that most people have correct time? On my school there
are about 20 computers in one place, and I checked the time for all of
them, all different, all wrong!
For my computers at home, I do have the correct Time, but Incorrect
time zone... (except 1 :P)
So, the information send to the server in the header would be wrong
for all PCs here in my LAN and at school, better said, 100% of the
computers I use pass wrong information, and so how reliable would that
header be?

The point is not how easy my Audio CAPTCHA is to crack, but rather
one of accessibility.

If one insist on using a graphic CAPTCHA, which in most cases can be
cracked, then at least add an Audio CAPTCHA to allow access for the
visually disabled.

Or, is the point here to allow bots and block the visually disabled
-- I think not.


Surely not, but what you're doing with adding a weak audio CAPTCHA is
adding more options for a hacker. Since the form can be submitted by
either completing one of both CAPTCHA programs, the hacker can choose
whichever way he likes. So if you have a very very strong Graphic
CAPTCHA, but a very weak Audio CAPTHCA, than it isn't too hard to
crack, as the hacker would only crack the Audio CAPTCHA...



Look at the CAPTCHA's use here:

http://sam.zoy.org/pwntcha/

and their efficiently at blocking bots, which next to nil.

So, if people are going to believe in the false notion that CAPTCHA's
block bots, then why not provide a way for the visually disabled to
obtain access as well? Why just block the visually disabled?


The question is not if the CAPTCHAs are crackable, because they are!
But, like we said in the other thread, it's by finding the right way
between the time needed to crack, and the time needed to type
over/listen to CAPTCHA. Adding Audio CAPTCHA decreases time to
crack...



>I think you remember the thread tedd ;)

I remember the threads, but nothing that was said there is counter to
what I said here.

It's atleast an interesting thread about CAPTCHA.

I know we can beat this thing to death, as we have in previous threads and I don't anyone wants to travel previously traveled ground. 

However, Rob said:

"A good captcha will try to exploit a computer's weaknesses."

So, let's expound on that -- what do you consider to be a computer's weakness?

Cheers,

tedd

PS: I know, better minds have reviewed this issue before, but this is now.

Well for instance as humans we can fairly easily recognize similar
shapes. We can recognize an apple whether it is red, green, yellow, has
a stem, has a leaf, is half eaten. A computer might recognize a circle,
and might guess that the circle is an apple based on further analysis.
But we as humans could recognize it as an apple even if we stretched it
a bit so it was no longer circular, or as I said, if it was a crescent
because someone had taken a huge bite out of it. This is something
humans excel at... inferring information from similar previous
experiences.

Taking the image captcha to a different level, one could combine our
ability to understand language as well as imagery. For instance we could
have an icon repository of animals, vehicles, plants, etc (very obvious
ones anyways). Then to create a captcha we could randomly select X
icons, slightly morph them to spoof matching them within the captcha
image itself, then ask:

    What animal do you see in the above picture?

I think someone already said microsoft or someone does something
similar. The principle is that we know what generally constitutes an
animal and a computer does not. Similarly, an audio complement would be
to have a background sound of maybe low level radio chatter overlaid
with the sounds of various everyday items... then one could ask:

    What did you hear ringing?

Possible answers... a bell, the telephone, an alarm, etc.

The problem then becomes an issue of people who can't spell or are
terrible at recognizing everyday things.

Cheers,
Rob.

Hello,

I would like to format the output of a PHP page into a single line and use
gzip compression too.

I know that i can use something like this to get in a single line ( will
workout on this function later to remove spaces ).

<?php
function my_function( $buffer )
{
                $str = str_replace( "\n" , " " , $buffer );
                return $str;
}

ob_start("my_function");

echo 'hello';

ob_end_flush();
?>

And gzip compression is used with

<?php
ob_start("ob_gzhandler");

echo 'hello';

ob_end_flush();
?>

Is there a way to "mix" those codes?

Thanks.

Output buffers can be stacked. So simply start the gzip bugger with ob_start, then call it again with your handler. The handlers will be called in reverse order when the buffers get flushed.
BTW, you don't need to ob_end_flush at the end of a script - this gets done automagically when the script ends.
