Peter,
For the first date:
-
$month = date("m") + 11;
$day = date("d");
$year = date("Y") + 1;
$newDate = date("Y-m-d",mktime(0,0,0,$month,$day,$year));
or
$newDate = date("Y-m-d",mktime(0,0,0,date("m")+11,date("d"),date("Y")+1));
-
And for the second date:
-
$month = date("m") + 11;
$day = date("d");
$year = date("Y") + 3;
$newDate = date("Y-m-d",mktime(0,0,0,$month,$day,$year));
or
$newDate = date("Y-m-d",mktime(0,0,0,date("m")+11,date("d"),date("Y")+3));
-
And that's all you need!

Paul,
You could check one of the following variables:
$HTTP_SERVER_VARS{"OSTYPE"}
$HTTP_SERVER_VARS{"SERVER_NAME"}
$HTTP_SERVER_VARS{"SERVER_ADDR"}
$HTTP_SERVER_VARS{"HTTP_HOST"}
or
$HTTP_SERVER_VARS{"DOCUMENT_ROOT"}
Check phpinfo(), it gives some really usefull info.

Well... then you should store the history yourself (eg. in a session or db). But then again... the $HTTP_REFERER isn't something to rely on. So then you'll need to store the current page in the history session/db. That way you always have the correct URL because it's the URL of the page the user is using. How much can go wrong with that? I think that's the best way. Actually I think it's even (a lot) better then the JS solution I mentioned. -- * R&zE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

And after using the back-button once, the last page was the 'next'. The HTTP_REFERER isn't some kind of history-list. If you realy want to go Back, why not use: JS: history.back(...); That way you really use the history-list of the browser. So after using it once, it's still a Back-button instead of a Forward-button. Besides that, using the $HTTP_REFERER isn't really something to rely on. $HTTP_REFERER doesn't always have to be set. In that case you can't go either Back nor Forward. -- * R&zE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Well I don't... but I _do_ know it's _really_ unique. It's never
the same. So actually I don't really know what to do with it.
Although probably at some time something will come up where one
would need it. I think.
To be short... FAIK it's exactly what's called: a unique ID.

I didn't say that your construction doesn't work, but it's not the
way to develop your sites. By using horrible constructions you can
make 'good-working' site, but that doesn't make it a good site. You
should always avoid using such terrible constructions. I mean... why
creating an image if you never intended to do anything with images?
Just because you want to have some weird construction on your site
and you can't think of anything else, soon enough?

It's the same kind of construction. You redirect the user to a completely
different page.

And for your other solution. Very usefull. Especialy when you don't have images on your page! What are you gonna do then? Create an image from 1x1 that's transparent or something? Can't get any worse. That's the SiteStat/Nedstat style. Awful! Besides that... what if I want to do some _serious_ processing instead of 'drawing' an image?

Christian,
This can indeed be a security issue. Try using
$HTTP_SESSION_VARS{"uid"} instead. It's a saver solution. Then one
cannot just use ?uid=10 in order to fool you. At least, not in that
way.

Re: [PHP] Re: prob with session start
I think I know what it is. The construction I mentioned to avoid the
reloading used three pages to login: the login-page, the validation
page and then some page that produces output to the user.
What you do, is include that output page in the validation page
(authentication.php). You shouldn't do that. Instead of the
include('super.php') you should use header("Location: super.php")
and instead of include('ordinary.php') you should use
header("Location: ordinary.php"). If you include
super.php/ordinary.php you still don't leave authentication.php.
That means that one can still reload authentication.php. Then the
browser asks for resubmitting the form. If you use header() instead
of include() you actually leave authentication.php and go to a
different page. The user can ofcourse reload that page, but that
page wasn't actually the result of a form-submital so the page will
then just be reloaded and no information will be resubmitted. Even
if one pushes Back from that page, he/she will not go back to
authentication.php but to login.html. And gone is your problem.
I think this should be your solution...
Oh... btw:
in authentication.php:
session_register('$emp_id');
should be:
session_register("emp_id");
and in logout.php:
session_unregister($emp_id);
should be
session_unregister("emp_id");

And no, you don't need session_destroy() when the user closes the browser. The session is ended automatically then. And btw, how would you detect whether or not someone has closed his browser?

Did you use session_start() in the file where you try to output data
from the session?

For the complete query-string: $HTTP_SERVER_VARS{"QUERY_STRING"}
Eg.: http://www.some-domain.com/index.php?one=xxx&two=yyy
$HTTP_SERVER_VARS{"QUERY_STRING"}: "one=xxx&two=yyy";
But you can also use:
$HTTP_GET_VARS{"one"} and $HTTP_GET_VARS{"two"}, etc:
$HTTP_GET_VARS{"one"}: "xxx";
$HTTP_GET_VARS{"two"}: "yyy";
Or you can use:
$one and $two, etc.
$one: "xxx"
$two: "yyy"

Just put them right before you want to sent some output. Or, ofcourse, right behind the session_start(). Think that should do the job.

Well... You can't sent any headers after some output has already
been sent. I didn't take a very good look at your code, but looking
at the warning you get and the position of session_start() in your
code, I'd say you have to move the session_start() up. You can best
start your code with session_start() and then the rest of your
script.

Using/emulating GET for security isn't realy a very smart thing to
do. Everyone can just use the URL as you show it. Using POST isn't
completely waterproof either, but at least you don't just give a way
your security information.

This is for an exact match of your example above:
preg_match ("/]+CONTENT=\"([^\"]+)\"/", $string, $matches)
If you don't know if it's in upper and/or lower case:
preg_match ("/]+content=\"([^\"]+)\"/i", $string, $matches)

Ehhh Weird!
I really start believing that it's either the directory you use in
$somevar that's wrong, or that the permissions are wrong. I have no
troubles wse with the constructions.
It doesn't matter if I only type the path, or that I put the whole
path in one variable or that I use both a variable and a (part of)
the path. The result is exactly the same. (as it should btw).

I must say: They're not pretty. Actually you can't prevent it. But: Option 1 You can set a cookie after logging in. The authorization page should check for that cookie. It should not exist in order to login. The login page (where one gives his username/password) should remove that cookie if it exists. This is, though, a _very_ ugly solution and using cookies for security isn't realy the best thing to do. So actually I wouldn't encourage you to use this. Option 2 Another solution is to redirect to a different page. I created the following example: =[ PHP code ]= // File: login.php Login Test // File: submit-login.php // File: logged-in.php /* Whatever you want! */ =[ end of code ]= After pushing the submit-button, the data will be submitted to submit-login.php. There you handle the login-procedure. After that, you automatically redirect to a different page (logged-in.php in my example). That's you you show eg 'You are logged in now'. If you reload that page, nothing realy happens. If you push 'Back', you end up on login.php again. Uptil now this is the best option I've come up with. Hope it works for what you had in mind. -- * R&zE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Are you sure the directory you try to open actualy exists?
Btw... for things like this you better use:
if (!($handle = opendir ("$bar/common/"))) {
// Some error here, and don't try to use $handle after this!

Nothing to worry about... PHP does it for you. You can try it you
know... Just use:
$currentmonth = 2; /* feb */
$currentday = 31;
$year = 2001; /* eg */
The output will then be:
2001-03-03
Ain't that most excellent?!?!
I should tell you though... that:
$3months = date("Y-m-d",mktime(0,0,0,$newmonth,$currentday,$year));
doesn't work. Obv. you haven't tried it. It produces an error (and
no date). Your variable name cannot begin with a number.
= PHP Manual =
A valid variable name starts with a letter or underscore, followed by
any number of letters, numbers, or underscores. As a regular expression,
it would be expressed thus:
'[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*'
= =
So I'd say: $threeMonths.

Are you sure function.php is included at all? Because if the only problem would be $bar, the output would at least be: someval from page.php from foo Like I said... I don't have any problems with it.

Checking whether or not a variable is set doesn't take any performance. Getting errors and warnings... that sucks. Some guy worked at this company who -we found out- hardly ever checked the results of his db-calls... just because that wouldn't look nice in his code. I mean... what kind of a person are you then. You won't believe how many errors and warnings his code produces. If you use functions calls and don't check the returnvalue(s) your just asking for trouble. And come on... tell me how much performance it takes to see whether or not the returnvalue is true or false after a db-function that takes up about 5 or 6 seconds. Then you're gonna complain about the performance you lose by checking if that db-function succeeded? Tell me... you have any warnings and/or errors logged to your logfiles? Or do you have the errorreportinglevel set to absolute nothing? You ever check if anything goes wrong?

Maybe you've heard about dynamic pages and stuff... Say: $a = 8.85; $b = 8; $c = 100; $result = (int)(($a-$b)*$c); And you know... we need an integer. Let's say for inserting into a db or so.

Point is that when using int, the damn thing doesn't get it straight. And that's WEIRD. I mean the result of (8.85-8)*100 is already an integer and not converting it to an integer the result is perfectly okay.

You could not be more right!
Always use stuff like $HTTP_SERVER_VARS, $HTTP_POST_VARS, etc. It's
the savest/best way!

Main word here is 'should'. Because they do. Ever searched for headers you can sent for forcing no caching. The one thing you always find is things like 'they should use this header, but they don't' or 'one proxy only looks at the headers, others only look at the contents'. I know how proxies _should_ work, but it turn's out that there are -to quote you- many "poor proxies". And I won't say that mine isn't one of 'm. But hey... I'm a programmer, not a system-administrator and stuff like the proxy isn't realy my thing. I know how they should work and I know we have one. But I also know (out of experience and theory) that proxies (just like browsers btw) don't always stick to the standards. And ehhh... I hardly use URL's including "?". You know... that's the beauty of sessionhandling. You don't need those ugly URL's anymore. But... besides proxies one also uses a browser for Internet-applications. And eventhough you can disable caching and history and stuff, those damn things _do_ remember things from the past and they think it's realy convenient to use that. It's quicker dude! Yeah, well: fuck it! I don't want it to be quicker... I want it to be right. -- * R&zE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Empty() doesn't return an error when $input isn't defined. I didn't RT(F)M on this one. I always use "(!isset($something) && empty($something))" to check whether or not $something is empty/not set. It's realy more of a feeling. Empty() actualy only checks for a value in $something. It's basicaly the same as "(!$something)" except that empty() doesn't return a warning if $something isn't set (...look, this time I did RTM :). So... basicaly, with empty() you don't check if $something is set. You just don't get to know it. So that's why I use isset() with it. I know the result is the same, but hey...

Cool... finaly. You won't believe how many people use echo(). And I realy don't know why. But, hey, if we take a look at many of the (pieces of) scripts you see passing by on this list people don't seem to care about error-checking. Many of 'm don't even look at the logfiles or don't have anything logged into them. And ofcourse I have to admit what's so interesting about error-checking printf? Well...

I never said, though, to use braces with echo. Actualy I didn't say anything about echo. I never use echo, for some weird reason I just don't like it. I prefer print. So... I don't realy care how echo should be used. But you'll have to admit, using braces makes things a lot easier. And because what this was all about was JavaScript (and not PHP), using braces is a smart thing, because in JavaScript you can make realy ugly constructions in which things _can_ go wrong (no syntax error, but _wrong_) if you don't use braces. In JavaScript it's not required to end each line with a semicolon like in PHP. This can cause weird flows if you also don't use braces. And e, who said anything about returning multiple values?

Oh... btw... I just gave a real look at that piece of code. You
might want to write it a bit different:
if (getenv ("HTTP_X_FORWARDED_FOR")) {
$ip = getenv ("HTTP_X_FORWARDED_FOR");
} else {
$ip = getenv ("REMOTE_ADDR");
}
$host = gethostbyaddr ($ip);
The other one does work, but quoting makes a lot of difference in
your logfiles. Without quoting yet get al kinds of warnings.

Anyway, here's the result of the thread... It's the code you need.

How about:
echo "balalala ".trim(odbc_result($result_id,3))." aasasasas";
or
echo "balalala [".trim(odbc_result($result_id,3))."] aasasasas";
depending on what you meant by the '[' and ']'.
This is just one of many possible ways of doing it. I, myself, am
not to happy with echo(). Don't ask me why, just a feeling... No
return value and stuff. I prefer using real functions that I can
check on being successful. So how about:
print ("balalala [".trim(odbc_result($result_id,3))."] aasasasas");
or
printf ("balalala [%s] aasasasas", trim(odbc_result($result_id,3)));
Well... as I said, many possibilities...

Ahh see, that wasn't clear in the question. Yeah... that's true.
Pain in the ass those proxies. They're also realy useful while
testing your (dynamic) site. NOT!!! "Hey, what's this? I thought I'd
realy changed that error. How's this possible?", "Didn't I just
change the background-color? Why is it still the same?"
BECAUSE THE DAMN PROXY DOESN'T WANT TO SHOW YOU THE NEW VERSION.
No... cache, cache, cache... Damn things always come up with pages
that are (way) to old!
But anyway... that's not what this was about (just my own
frustration). But I just don't use the proxy nomore. Only for
testing things like REMOTE_ADDR etc.
But thank you for specifying the question. And eh, you're right. I
just didn't know the question was about this problem.

It no _might_ mess things up... It sure does! Good one.
But... another thing. You just might want to consider using braces.
They're not invented for nothing. When you call functions (like
return) you should use braces. Especialy when you start writing more
complex scripts, the not using any braces, is just the thing that
may because a lot of trouble.
Weird thing btw, that the JavaScript console doesn't show any errors
when there's a newline between return and verifyInput. I mean...
it's a good example of a syntax error. But that stupid console
doesn't show any damn thing.
Btw... not that it matter anyway, but:
onsubmit="return <\n> verifyInput();"
doesn't do the right thing (as we've all seen), but:
onsubmit="return( <\n> verifyInput());"
does. (...)
> well, if it makes it this far, $input will be set, but the value will

Well, Mark... almost! You shouldn't use empty() _instead_ of
isset(). You should use 'm together:
if (isset ($input) && !empty($input)) {
print ("Okay... form is completed!");
} else {
print ("No way... can't do!");
}
Because, when you check using empty($input) there's still the
possibility that $input isn't defined at all. And then some horrible
error still arises in your logfile.
Note btw that you shouldn't change the order of isset() and empty()
in the above example.

Correct me if I misunderstand you're question, but;
If you use HTTP_POST_VARS you already have the variable names. I
mean... how else do you use the values you're talking about?
$HTTP_POST_VARS{"var_1"}, $HTTP_POST_VARS{"var_2"}, etc.
var_1 and var_2 are the variable names...

Why the H*ll would you wanna use echo there?!?!?!
Just fopen($agentcode."CyberTrac.ctr", "w"); works (like someone

Comparison: == Assingment: = (and _not_ the other way 'round) And then... Why would you even think about comparing to fixed strings? You wouldn't. So I guess you'd like to send some real code next time, so people can see what you're trying to do. And then... "inf" = "inf" doesn't work _at all_! It produces an error. If you use "inf" == "inf" the result is exactly what you'd expect. And then... In your real code, which is something like $var = "inf", you should use $var == "inf".

Okay...
First:
Checking if $shiny equals 0:
if ($shiny == 0) {
But that's already been discussed.
If you _realy_ want to check if the assignment succeeded:
if (($shiny = 0) == 0) {
Try the following example:
-
$a = "Hello";
$b = "Wold";
if ($b == $a)
print "Yes, b equals a\n";
else
print "No, b doesn't equal a\n";
if (($b = $a) == $a)
print "Yes... now b equals a\n";
else
print "Oops... b still doesn't equal a!\n";
-
Output will be:
No, b doesn't equal a
Yes... now b equals a

In order to completely destroy the session:
session_destroy();

Why not use some hash io separate variables? And, eh, why do you
quote integer values? What I would suggest is something like this:
/* Just as you already had */
$folder[0] = "basic";
$folder[1] = "standard";
$folder[2] = "knowledge";
/* -- HASH -- */
$totalsub{"basic"} = 10;
$totalsub{"standard"} = 24;
$totalsub{"knowledge"} = 12;
In this way it's easy to access the totalsub-values:
e.g.: $totalsub{$folder[0]}

Good idea... that $. Also the checkdnsrr is a nice feature. But
I'll have to remind you on a previous thread about quite the same
problem. The checkdnsrr can slow down the performance of your own
site. It _can_ make it terribly slow. Draw your own conclusion.

Well; PHP is server-side, so without resubmitting the form you won't
be able to do this using PHP. That's why JavaScript is available. At
this time I don't have enough time to explain exactly how to do
this, but JS is the way for this.
If your in a hurry and noone else in this list _has_ got the time to
'finish' my msg, try posting a msg on a JavaScript newgroup.
E.g.:
secnews.netscape.com: netscape.devs-javascript
I'm sorry I can't help you out further at the time.
Good luck!

Have you ever checked the $HTTP_USER_AGENT value from IE?
IE says:
"Mozilla/4.0 (compatible; MSIE 5.01; Windows 95)"
(for example)
So, you shouldn't be checking for Mozilla. IE says that to.

E No!
PHP is server-side. Using PHP you can't do that. Only thing you can
do is have PHP generate the JavaScript that calls window.confirm().

You guys aren't validating an email-address. You just send something to an address some gives. If the mail doesn't arrive bad luck for that guy. That's no way of validating an address. That's just sending an email to whatever address someone gives. Realy validating the address is checking whether or not it exists _WITHOUT_ sending an email. Sometimes you just have to live with those things that aren't possible like quickly and savely validating an email-address. Like Steve and I already posted; you can check the domain and that's it. Everything that goes beyond that is just trail-and-error checking. That's not the way. E.g. if you have some site and you want to collect marketing information you want the email-addresses to be correct. But _noone_ will ever fill out some form -> check his mail -> come back to a given URL -> and validate some password. That's only a possibility for sites where people can create an account of some sort. When it just concerns some visitor information, there is no reliable way of checking the complete address. Just like e.g. the first- and lastname of the visitor. You just _cannot_ check that! -- * R&zE: *** ** Renze Munnik ** ** E: [EMAIL PROTECTED] ** M: +31 6 218 111 43 *** -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] Validation Email in PHP programs
Yep Steve is a smart man. The solutions I gave are good but can ruin your own performance totaly without it being your mistake. The bad performance of a different server (which you probably don't even know!) can ruin the speed of your site. Depending on the importance of the check you'll have to decide yourself what to do. If you _do_ want to check the email-adresses using the mx-checks, but you don't want to take the chance of slowing down your site, you can always consider batch-processing. Accept the addresses based on the RE and store them (e.g. in a db). Then at night (or whenever) you can start a script that iterates through the list, checking all mx-entries. And for the usernames that you can't track. It's the nicest feature a mailserver has! You wouldn't be able to do anything normal anymore if the users could be tracked. Every spam-"service" would be scanning your mailserver and spamming it to death!! So... you'll just have to accept the username... -- * R&zE: *** ** Renze Munnik ** ** E: [EMAIL PROTECTED] ** M: +31 6 218 111 43 *** -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Besides the RE you might wanna take a look at these functions:
http://www.php.net/manual/en/function.getmxrr.php
and
http://www.php.net/manual/en/function.checkdnsrr.php
Using (one of) those you can check the email-address better. I.e.
the domain. Extract the domainname from the given email-address and
feed it to either one of these and you'll get a result whether or
not the domain has an MX-record. Only thing left is whether or not
the user exists on the given mailserver. But for as far as I know
you can't automatically check that.

Using the gzhandler works just fine with NS. The problem hower is a different one. The page is shown perfectly, but when you try to print it, NS 'forgets'(?) to decompress it. _That's_ what's wrong. Another thing is 'view source'. Then (I think) NS doesn't decompress either, 'cause NS then says that the document is 'Untitled' and no code is shown _at all_. And for the HTTP-thing I started You're exactly right! Painful to see the answer on a question and notice that the answer is _SO SIMPLE_. "Just go to Tools, go to Internet Options, go to Advanced, disabled 'Use HTTP/1.1'". G, and then knowing that I've been developping and testing for years now. Something so extremely simple, and I just _DID NOT THINK ABOUT IT_. Anyway... I disabled it and it makes no difference. Conclusion (for now...): HTTP/1.0 is not the problem, NS is. Another lovely bug from the NS-services. So This was a pretty useless try from me.

[PHP] GZip: NS or HTTP/1.0
Okay guys I've got a new idea
I just found out that NS<5 uses HTTP/1.0 and not HTTP/1.1. Well,
okay, but that's not _to_ exciting is it?! But... (there's always a
'but') IE>=5 uses HTTP/1.1. Now, looking back at the subject being
discussed in this thread, I'm wondering if that might be the problem
that arises when using the gzhandler.
Example
On our server we use the multi-views: no extensions required! So,
instead of calling 'page.php' I just call 'page'. Nothing wrong with
that, not even for NS. But... (there it is again!) I made the
following (test) page:
PHP Info
BODY {
background-color: #ff;
}
I've named this file 'php-info.php'. So... Now I call this page from
IE (5) calling 'php-info'. Guess what? Nothing wrong; works
perfectly! And now the big NS test. S*cks!!! Calling 'php-info' from
NS provides me the next error:
..."no acceptable variant: "...
This error is server-side and only occurs when using HTTP/1.0. So I
was wondering if the HTTP/1.0 can also be the cause of the printing
problem concering the gzhandler?
If that's the case I should disable the compression for each and
every browser that uses HTTP/1.0 instead of only disabling it for
NS.

You use relative links to your images. It's not so weird that
someone who receives the page will not get the images with it. If
you want the images to be seen by the rcpt, you should use absolute
links to them. Usualy you wouldn't want to do that, I agree, but
when sending pages all over the world, there's pretty much no other
way. So e.g. the first image will be:
http://www.gondwanastudio.com/Expedition/Episodes/xMedia/Logo/MiniLogo_BushWeb.gif"
width=" ... etc.
That way, the rcpts will be able to see the images.

Re: [PHP] GZip + NS + Print = Trouble
Yep... You're right (again...). Though I must say that the transfer _is_ a 'problem'. Not only for NS users, but for most people, because let's face it; most people still use a modem (39K, 56K...) for Internet and not the 2Gb line that I have. I've got not problems with transfer-speed at all, but those people at home will. Ofcourse I know that making my pages less big would be a good solutions, may hey... it makes 'm look and works so very nice. What I mean is; I didn't say that NS transfers slower, but the people who use my sites have to download a lot of sh%t that I wrote (well, not exactly sh%t, 'cause I do get paid for it) and to speed that up (most Internet-connections at home s~ck) I wanted to compress the data being transferred. And the gzhandler was a good sollution. I mean... HTML still _IS_ plain text and that compresses like reealy good. And the unzipping on the clientside hardly takes any effort, so... But now I'm writing to much. You're right. That's what this was about. The solution like I have it now doesn't work for NS; that's for sure. So for the time being I'll just adjust my 'headers' (cry, cry, cry) so that the gzhandler isn't used for NS. God I hate this!!! When ever anyone has _some_ (sort of a) solution for this afterall...

Re: [PHP] GZip + NS + Print = Trouble
A well... what shall I say. I have to agree with you _A LOT_!!! Netscape ruled, but doesn't anymore. It's a damn shame. They pretty much stick to the standards (which I like very much) but the program (browser) is f*cked up. Anyway... My pages contain some tables about three within each other. And NS can't handle tables to good. So if there is any browser I'd want to use compression for... it'd be NS. That way the data would be faster there and NS should have more time to process it. So I'm not realy looking for I solution that only works for IE. Because only compressing it for IE was something I'd thought about already, but I don't realy think it's a reasonable option. But... Thanks for spending your time to my problem!

Re: [PHP] removing $HTTP_POST_VARS
The referer isn't always defined though... not even if it would be a
valid one. Some browsers just don't want to cooperate...

Re: [PHP] JavaScript and Submit
Ehhh... do you want to have them all go to the same page after a
submit?
With real submit buttons:
If you don't, you can just change the 'action' of your form at the
moment that someone pushes one of the submit-buttons.
With 'fake' submit buttons:
Otherwise (if they all have to go to the same page) I'd say you can
just add a hidden field e.g. and set the value to either 'sbm_1',
'sbm_2' or whatever, at the moment someone pushes the button. Then
at the 'result-page' you can check that field and look what the
value is. Another way is (if you want to use the exact check as
you've described) to create three hidden fields (submit1, submit2
and submit3) and assign a value to the one corresponding to the
pushed button.

Re: [PHP] comparing dates works sometimes and fails another time!
If you _do_ want to use this method for comparing dates (which isn't realy a usual way of doing it... there date-functions) you should fill up with leading 0's, like: $date1="2001-01-07"; $date2="2001-01-14"; The reason is _very_ simple... You performing a text-compare here. And let's face it... the characters "-1" (day of date2) are "smaller" than "-7" (day in date1). So...

Re: [PHP] GZip + NS + Print = Trouble
Thanks for bringing up this solution. However... I already thought of this option myself. Problem, though, is that _ALL_ my pages should be printable. Maybe a very small number of pages will not have to be printable, but those are so small that the compression isn't realy necesary. Besides that I don't realy like sites that use separate 'printer-friendly' pages. When I'm looking at some page I just want to be able to print it rightaway. And I want to give my clients this opportunity to. That's why I also have a separate (extra/own) print-button on my sites. The user can just use that without realy having to know how the browser works (concerning printing). Because you will just not believe how 'stupid' some users are. But anyway... any other solutions are ofcourse _very_ much welcome and I'll keep y'all posted a.s.a. I get some more info about this subject.

[PHP] GZip + NS + Print = Trouble
Okay
ob_start ("ob_gzhandler") is a very cool thing to use. At least when
you write _to much_ code like I do. And it works perfectly
most of the time, i.e.
I've got this problem:
My pages start with the gzhandler (see above) to decrease the amount
of data that should be transferred. Nicest thing is that if your
browser doesn't support any compression, the data will be sent
uncompressed. Very cool. But then Netscape... It understand gzip.
Yes it does but they forgot something. At the point that you want to
print out the page your looking at in your browser, Netscape forgets
to unzip the data. Guess what... a whole lot of crap on the paper.
Well not very much ofcourse _BECAUSE IT'S COMPRESSED!!!_
I don't realy like this bug and I'm wondering if someone maybe has
some solution for this

Re: [PHP] Header Problem...
There may not be any headers before you use the 'header' statement.
The header("Location:...") should be the first output you send. You
might want to consider moving the two 'anti-cache' headers after the
header("Location;...") statement.

Re: [PHP] reading a URL...
Just use $id in your code. That should do the job. Variables that are passed using GET or POST you can just use in your code. Ofcourse you have to add the $-sign. So if you use the URI: http://www.arandomsite.com/news_story.php?id=123 You can just use: "SELECT xxx FROM yyy WHERE id=$id" RenzE.
