By default the CLI version turns off the html in the error messages. And no, really, there is no bug here. You are testing the return code of something that doesn't have one.

The list has been configured this way for years and years and believe me, it is the safest and most flexible configuration.

This seems to describe the tone of the debate. The idea of an authority on a matter that is incapable of considering alternate viewpoints seems oxymoronic to me. It was an authoritative answer in the sense that I'm the guy who would have to be convinced to make this change and I really don't see this happening. I do understand all the arguments and I have duly considered them. Believe it or not, but I actually know a little bit about this stuff. Here are just a small set of reasons to keep things the way they are: 1. Default to safety! If I think I am sending a private email and unknown to me it ends up going to a public mailing list with hundreds of subscribers and archives all over the Net, there is no way to undo the security breach this could cause if I inadvertently put some non-public information in my reply. If the odd message intended to be public instead ends up private, this is a small price to pay and something that can easily be remedied by either the sender or the receiver after the fact. 2. People often want personal responses - There are many interfaces to the PHP mailing lists and people do not need to be subscribed to send a question to one of the lists. If you are not subscribed to the list, it is very nice to get a private reply to your question and all other replies in the thread which is exactly what happens when people properly do a reply-all - Sometimes the mailing lists are slow to propogate messages. By also sending a private reply the person asking the question gets a much quicker response. And no, the but I don't want two copies isn't much of an argument. Any decent mail system should be able to weed out duplicate messages. The following procmail rule does it, for example: # Remove duplicates :0 Whc: msgid.lock | formail -D 16384 msgid.cache :0 a: duplicates I'm saving a copy in duplicates, just in case here, but you could also just trash the copy. And yes, I realize not everyone has the ability to install their own procmail rules but again, this is a technical forum with a lot of people who can do this stuff. Dumbing down and crippling the list to cater to the less fortunate at the expense of the rest of us is not going to happen. This might even help push others to use more advanced mail clients and mail servers. 3. Avoiding misconfigured mailers from trashing our lists I often see vacation messages and other crap on lists that have the reply-to set to point back to the list. This has also been known to cause mail loops with dozens of copies of this stuff getting sent to every subscriber of the list. 4. Quality over quantity I personally don't think it would be a bad thing if we saw less replies go directly to the mailing list. Especially for high-volume php-general where there are a lot of newbie questions. If you know something has been answered dozens of times publically, a quick private response is fine. And if the person asking the question would then optionally post a summary later on our signal to noise ratio would go up considerably. 5. Deleting existing reply-to headers? Most people would agree that if a message is sent to the list with an existing reply-to header, then it shouldn't be deleted. Because if you delete it, there may be absolutely no way to reach the original author. The purpose of the reply-to header is to allow you to specify where you want replies to your message to go. You could even send it from someone else's account and set the reply-to to your address and should should reasonably expect replies to end up at the address you specify. Now, if that holds, then only setting the reply-to on messages that don't already have a reply-to, which some mailing list software does, means you now lose consistency. Sometimes a reply will go to the list, sometimes it won't. I could rhyme off another 5-10 reasons here, but even stopping after #1 in the above list is more than enough for me to justify the current list configuration. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Myself and several others have looked extensively for the answer to this and we've tried all the viable remedies that have been suggested. Does anyone have any suggestions?

If you use a threaded mpm (anything but the prefork mpm) you are likely to run into issues under load. We still suggest using Apache-1.3.29 for any sort of stable production server.

It is natural that a static file version of a big complex page will render faster than the PHP-generated one. You can ask Apache to flush its internal buffer by using the flush() call from PHP, but it really isn't advised to do that too often.

RE: [PHP] Re: Red Hat 9, Apache 2, and PHP
Apache2 has a number of different modes it can work in. These modes are called MPM's. The default MPM is called Worker which is a multithreaded model. PHP, mod_perl, mod_python, and any other similar technology which links directly into the httpd processes will need to be perfectly threadsafe and reentrant to work effectively with a threaded Apache2 mpm. This is doable for the core of PHP, but there are literally hundreds of 3rd party libraries that can be linked into PHP and nobody whether or not these libraries are threadsafe. And figuring out if a specific library is threadsafe or not is non-trivial and it can very from one platform to another. And just to make it even harder, this stuff will appear to work fine until you put it under load or hit very specific race conditions which makes it nearly impossible to debug. So, since we can't tell you for sure that a threaded Apache2 mpm + PHP will work we do not suggest you use it for a production server. And since we can't know for sure, none of the main PHP developers use this combination for our own servers which compounds the problem because it is not receiving anywhere near the amount of realworld testing required to work out all the little issues above and beyond this threading unknown. There is an Apache2 mpm, called prefork, which isn't threaded and basically makes Apache2 look like Apache1. But hey, we have a very good server already that looks like Apache1. In the end I don't see Apache2+PHP ever becoming a production platform with the current architecture. The only way I see it ever working is to pull PHP out of Apache and use a fastcgi approach. Or, with time, perhaps we will learn how to make sure a library is perfectly threadsafe and safe to use in a multithreaded Apache2. For now, I really see no reason not to simply use Apache1 if you want a robust, fast and stable web server. -Rasmus On Fri, 4 Jul 2003, Ow Mun Heng wrote: Does anyone have any idea or could give me an idea why php apache 2.0 is not 'good' together?

Functions defined in included files are always global. So I guess it is

Re: [PHP] Snarl, hiss, growl (frustration)
The difference is that you are getting a string from the file and not
casting it to an integer. You could also have fixed it by doing:
$counter = (int) fread(...);
Note however that you have a nasty race condition in your script. If you
get concurrent hits they will all read the same counter value out of your
counter file, increment it, and write the same value back. So those hits
will not be counted.
An easy way to get around this is to only open your file in append mode
and add a single char to the file for every hit. filesize() on the file
then gives you the count. The advantage here is that an append to a file
is guranteed to be atomic and you won't have that race condition between
reading and writing the file.
The other way around it is to lock your file, but locking files in a web
app is a really bad idea.
And finally, to really make a robust counter, use a database and an atomic
count=count+1 query.

maybe you need to end the if() statement before incrementing the
counter.
$ip = getenv('REMOTE_ADDR');
$ipCheck = file('ips.txt');
if (!in_array($ip, $ipCheck)) {

RE: [PHP] php5 and mysql licences
On Mon, 30 Jun 2003, Dan Joseph wrote: Is the mysql client library going to be put back in for future betas? Or are we mis-reading the change log and its still there? There will always be MySQL support in PHP of one kind or another. The only change in PHP5 is that we are no longer bundling the client library itself. Some reasons in no particular order: 1. Most systems these days already have the client library installed. 2. Given 1, having multiple versions of the library can get messy. For example, if you link mod_auth_mysql against 1 version and PHP against another and then enable both in Apache, you get a nice fat crash. Also, the bundled library didn't always play well with the installed server version the most obvious symptom of this being disagreement over where to find the mysql.socket unix domain socket file. 3. Maintenance was somewhat lax and it was falling further and further behind the released version. 4. Future versions of the library are under the GPL and thus we don't have an upgrade path since we cannot bundle a GPL'ed library in a BSD/Apache-style licensed project. A clean break in PHP5 seemed like the best option. This won't actually affect that many people. UNIX users, at least the ones who know what they are doing, tend to always build PHP against their system's libmyqlclient library simply by doing --with-mysql=/usr when building PHP. For the beta1 release, it went out without a mysql.dll extension because we haven't quite worked out how to handle it, not because the final PHP5 release will not have MySQL support. Of course it will and Windows users will not be affected. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Guys, this will not change. Look back through the archives. It has been discussed a couple of times. If you don't like it, unsubscribe. Sorry to be blunt, but this is a waste of bandwidth. Keep in mind that many people post without being subscribed to the list, so only sending a reply to the list doesn't get them the answer they were looking for. Also, often the list can get slow and getting a private copy of the answer to your question means you don't have to wait an hour or more for it. If you don't know how to configure your mail system to get rid of duplicates, then you will have to suffer through hitting the delete key an extra time.

What does it do? Using connection_status() in a script that doesn't
ignore user aborts is pretty useless. The script will abort on the print

actually make any sense. And, beyond that, all bets are off for
Apache-2.0.x. No real extensive testing has been done on that platform
which is why we don't suggest running it in production because stuff like

This would be an example:

Here, since you haven't initialized $str and you are appending to it,
someone can inject something into $str via GET or POST data. To fix it,
you have to make the code:
$str = '';
for($i=0;$i10;$i++) {

Is that really what you find incredibly annoying? Even without

Re: [PHP] Shipping Rates
Better approach in what sense? From a performance perspective you are not
going to beat a specific set of if conditions unless there is an distinct
formula you can apply. I will assume there is no simple mathematical
relationship for your full set of data and what you are really looking for
is a way to just feed the pricing structure into your code by some
mechanism and then have it just work, so your goal is to make it more
maintenable. To that end, you could stick your pricing table into an
array of arrays and simple loop through it. Something like this:
function find_rate($num) {
$rates = array(array('7.45'=20),
array('8.45'=35),
array('9.45'=55),
array('10.45'=80),
array('11.45'=100),
array('13.45'=150),
array('15.55'=200),
array('19.45'=9));
foreach($rates as $i = $vals) {
if($num current($vals)) continue;
else { $price = key($vals); break; }
}
return $price;

This should return the correct shipping price for whatever you pass into

Here is an example of my shipping rates:
Less than $20.00 = $7.45
$20.01-$35.00 = $8.45
$35.01- $55.00 = $9.45
$55.01-$80.00 = $10.45
$80.01-$100.00 = $11.45
$100.01-$150.00 = $13.45
$150.01-$200.00 = $15.55
$200.01 or more = $19.45
Thanks.

RE: [PHP] RE: connection_aborted was [PHP] trikky authenticationquestion
?? Are you reading that chapter at all? Closing the browser has absolutely nothing to do with aborted connections unless the browser is closed while data is actually flowing across the wire. You are completely on the wrong track here. HTTP is a simple stateless protocol. Sessions can be used to emulate state, but that doesn't mean you suddenly have a stateful connection-oriented protocol. Between clicks of your browser you do not have an active connection from the browser to the web server (with the minor exception of keep-alive connections, but they aren't what you think anyway, so ignore those). Since you don't have an active connection, closing your browser could not possible abort a connection. -Rasmus On Sun, 1 Jun 2003, electroteque wrote: of course thats where i got the example from but it doesnt work ignore_user_abort(true); if (connection_aborted()) $this-db-query(UPDATE users SET logged_in=0 WHERE userID=$this-userID); if i close the browser its not setting the fiel to 0 meaning they are logged out -Original Message- From: Rasmus Lerdorf [mailto:[EMAIL PROTECTED] Sent: Sunday, June 01, 2003 5:46 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Re: [PHP] RE: connection_aborted was [PHP] trikky authentication question On Sun, 1 Jun 2003 [EMAIL PROTECTED] wrote: how can i get this to work ?? if (connection_aborted()) $this-db-query(UPDATE users SET logged_in=0 WHERE userID=$this-userID); Did you read the connection handling chapter in the manual? http://www.php.net/manual/en/features.connection-handling.php -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Sessions can be dangerous
On Fri, 30 May 2003, George Whiffen wrote: 1. Heterogeneous Code Environments php session data is not easily accessible from non-php code e.g. Perl/C/ASP etc. In contrast, either client-stored data e.g. cookies, hidden posts, get variables, or data stored in a structured database table, (i.e. one column per variable), is easily accessible from other code. For anything beyond a trivial application, you are going to be writing your own backend save_handler anyway, so I don't really see how this is an issue. If you don't want to write your own save_handler (which is really really easy) you can always just set session.serialize_handler = wddx in your php.ini file and you will have the data stored in a standard XML format instead. This format is very accessible from non-PHP code. 2. Provably Secure Authentication Data Hopefully we all know by now that the best way to safely authenticate for access control is to make sure the username/password is checked every time either by your script, your webserver or a trusted third-party. However, I have the feeling some session users are tempted to simply authenticate in one script and store a logged in or username flag in the session without the username/password having been re-validated. Sure, but this isn't really specific to sessions. I would say this is related to any cookie a developer might create. There is always the temptation to not include the auth headers on each page and just toss the logged in user id into the cookie. This is obviously a bad idea, but I wouldn't necessarily attribute this to an inherent danger in sessions. 3. Independent Audit of Server Stored Data Procedures for independently verifying the data stored on a server in a SQL RDBMs are well established. It is easy to query the database schema to see what columns are defined. It is easy to verify that the data actually held in a column is as expected. In general it is easy to prove and verify what data is held e.g. to prove Data Protection compliance or Bank/Credit Card requirements, (no storage of cvv2 for example). It is intrinsically much harder to prove that the contents of php session data are compliant. You need to write a php script to unpack the session data. That means proving that that script itself is safe. Even after you've unpacked the session data, you still have to make sense of it. Different sessions may hold different numbers of differently named variables. But that's not all, the same variable may hold data in different formats in different sessions! Again, see point 1. Any real usage of sessions is going to need a custom save_handler most likely written against a real database. You simply cannot go beyond a trivial single-server web-app without doing so and the facilities in the php session support for doing this is good. 4. State-ful Designs My personal concern about sessions, is more about the design issues. What worries me is that sessions may be used to try and re-create client/server style state when the most distinctive advantage of the internet, (and the key to its astounding success), is that it is fundamentally state-less. What this means, is that the internet is based on the principle that every request is entirely self-contained and independent of any other request. There is for example, absolutely and explicitly, no guarantee that http requests will be received in chronological order. It is all strictly about best effort, and no guarantees. This is why the internet works: each component does its own job as well as it can without worrying about what else is happening. The boat has long since sailed on this one. People need and want to maintain state. You can't build any sort of shopping-cart style site without them. 5. Reduced Component Reusability ... On the other hand if the update is coded as a proper component i.e. it reads the key of the data to be updated from the http request, (GET, POST or COOKIE), then you can automatically allow it to be accessed from anywhere without having to always go through some particular search/list/select sequence. I tend to distinguish between the human interface to an app and the machine interface. Trying to put them both into the same interface tends to make them cumbersome for both sides. Often the human interface is just a thin layer on top of an underlying machine interface and it is at the machine interface that you have your reusability and transparency. In a properly designed architecture, the session layer is simply part of the human interface and really doesn't affect the reusability of your base machine interface. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] making sense of time(), date() and strtotime()
If you have your date components split up already the way you do, you
should be using mktime().
Next you have to determine which timezone your information is from. If
you consider your month/day/year values to be GMT values, then use
gmmktime() to generate your timestamp. Otherwise, make sure you
putenv(TZ=whatever) the timezone that matches your data before your call
to mktime().
It is important to understand that a UNIX timestamp (seconds since 1970
epoch) carries no timezone information. A single UNIX timestamp
represents one specific second all over the world. That is, if I gave you
the timestamp for when my baby was born, it would be the exact second this
happened. This might be Monday here, but Tuesday in Australia. Timezone
information is only applied once you go to display a human-readable date
from the unix timestamp. gmdate() is just a special-case that does about
the same as:
$old = getenv(TZ);
putenv(TZ=GMT);
echo date(M d Y H:i:s,$timestamp);
putenv(TZ=$old);
It is in there because GMT is needed for all sorts of stuff and we figured
having a shortcut version of the above was a good idea.
If you really want to use strtotime() you can just tack the timezone
associated with your data onto the end of the string. In your example:
strtotime({$_POST['month']}/{$_POST['day']}/{$_POST['day']} GMT);
if your month/day/year are in GMT.

I have $_POST['day'] (1-31), $_POST['month'] (1-12), $_POST['year']

I store all dates as unix (epoch) timestamps, and generate the timestamp for
the event with:
strtotime('{$_POST['month']}/{$_POST['day']}/{$_POST['day']}');
Everything works fine on my LAN (Australia), but when I upload my database
to the live server (US), the dates are a day behind (when echo'd with
date('Y-m-d')), presumably due to the time difference between the two
servers.
Timestamps generated directly on the live server appear correct when echoed
out using date.
How can I reliably generate timestamps which will work on any server, and
reliably convert these timestamps to human readable format (eg
date('Y-m-d')) on any server?
Is the key to use GMT in the strtotime() string and use gmdate() instead of
date()? Or is it more complex than that?

Kind of a follow on question to this. If you use a method like this on
public web pages, does anyone know if it'll affect how search engines
index your page? Will they ignore it because it's expired? Thanks.
No, as far as I know at least google does not ignore cache-expired pages
like that. There is a No-Archive meta tag you can put in your page to
tell it not to archive, or of course, you can robots.txt it.

RE: [PHP] Re: Found a bug in 4.2.3 re: TD and echo vs. ?php?
You are getting completely mixed up. Simplifying your example:
function foo() { echo foo; }
$a = TD.foo()./TD;
Will you agree that this is bogus code? foo() is not going to return
anything, so the resulting value of $a is going to be TD/TD.
Correct? But while that assignment is happening the foo() function echoes
something, so you will see foo in the output, but it has nothing to do
with what ends up in $a. Nothing changes when you change the code to be:
function foo() { echo foo; }
echo TD.foo()./TD;
The parser is going to build a string to be echoed since you used the
string concatenation operator (dot). While building that string one of
the components happen to output something, so that something will get
output. Then the string that was built will be output. So what you see
is:
fooTD/TD
Perhaps it is clearer if we make the function return something:
function foo() { echo foo; return bar; }
echo TD.foo()./TD;
What do you think the output will be here? We build a string out of the
components, but while building, foo() happens to echo foo, then we
finish constructing the string and output the final string. So the result
is:
fooTDbar/TD
As someone else pointed out, if you use commas here, things change a bit:
function foo() { echo foo; }
echo TD,foo(),/TD;
The comma syntax for echo is basically a shortcut for executing echo
multiple times. The above is equivalent to writing:
echo TD;
echo foo();
echo /TD;
In this case things will be output in the correct order as we are no
concatenating a bunch of parts to make a single string before echoing it
in this case.

Re: [PHP] Running scripts in non-php file
That should be all you need. Make sure that something isn't re-assigning those extensions later on in your conf file. Perhaps you changed the wrong addtype?

I thought all I had to do was add the extension to the AddType application in the apache configuration file so it looked like this: AddType application/x-httpd-php .php .html .xml I tried it but the code isn't being executed.

Re: [PHP] Re: parse_str()
Jose [EMAIL PROTECTED] wrote in message
news:[EMAIL PROTECTED]
I might be wrong here, but with the code below I would expect $_GET to be
filled and the script to output the next line:
?php
$example_string = 'action=kickitem=me';
parse_str($example_string);
var_dump($_GET);
?
// expected output:
//
// array(2) { [action]= string(4) kick [item]= string(2) me }
//
Is my assumption wrong? What would be the workaround?
Your assumption is way wrong. $_GET will only contain data that actually
passed through a GET-method request. Decoding a URL-encoded string
doesn't suddenly make it GET data. It will simply create entries in your
global symbol table, or alternatively you can pass a second argument which
is an array it will put the data into. As per the docs.

case strpos($line,#date:) == 0 strpos($line,#date:) !== false:
You can just do a === 0 check here, you don't need the second
check to make sure it isn't false. However, that's not really how you use
a switch expression anyway. The expressions in the case statement should
be constants. If you rewrite your code to look like this it will work

Re: [PHP] 2 PHP 4.2.2 issues: server keeps working after clientdisconnects, session_start() blocks until other session scripts complete
Hello all, I have 2 questions that have come up because I have several long reports that can take 1-2 minutes to run. These are run from any web client thru our linux - apache - php - mysql system. 1)server keeps working after client disconnects If a php script is running and it may take 1-3 minutes, and I hit escape or close my web browser window, the script keeps running. I can see it in top, consuming lots of cpu and sometimes ram. Why doesn't apache and the php4.so notice the closed tcp connection and abort the script? Is there a way to make this happen? Yes, this happens by default, but we can only catch it if we try to write something to the socket and get an error back. If you are processing and not outputting anything, there is no way for us to tell. If you are able to write out some sort of progress indicator during your processing then it would work. 2)session_start() blocks This sounds odd. session_start() should not be blocking. What sort of backend datastore are you using for your sessions? -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] short_open_tags = On
No, there are no security implications. In fact, it is arguably more secure to have short tags enabled as it is then less likely for someone to accidentally expose their PHP source code since everything between ? and ? will be parsed by PHP. However, keep in mind that XHTML and XML also uses ?...? so if you are mixing XHTML or XML with PHP you could run into some difficulties. Nothing that is all that hard to get around. I tend to always use short_tags myself and simply echo ?xml...?; if I need to output an xml revision tag, for example. -Rasmus On Tue, 4 Mar 2003, Keith Mastin wrote: I was asked to change this in the php.ini file by a user to make it easier to use php on the server.

Yes, I have noticed some performance issues as well, but we need to nail it down better before we can start really going after this. Could we call on the collective masses of php-general users to run some benchmark tests? Just build yourselves a libphp4.so for both 4.2.x and 4.3.x and switch the LoadModule line back and forth to benchmark the two versions.

I noticed some very strange behavior which leads me to believe 4.3.0 is not stable, and shouldn't be used in a production environment. So, all I can suggest for now is to determine what it is you need, and if a newer version of PHP will suit, go for it.

Re: [PHP] testing for negative numbers
Please provide a complete test script. Are you perhaps not realizing that array indices along with all variables in PHP are case sensitive? $row[ID] and $row[id] are not the same thing. The trivial test of your example: $myArray[id] = -2; if ($myArray[id] 0) echo Negative; else echo Positive; Prints Negative as expected. -Rasmus On Thu, 6 Feb 2003, Robert Samuel White wrote: I realize this should be about the simplest thing in the world to do, but for this reason or that it's not working...

Re: [PHP] Why PHP doesn't work with Apache2?
Henry wrote: what issues for example? I do know I can successful install php in module with apache2.0.43 without error messages, also execution was successful can you tell me what issues did you see? A successful install means nothing. My question is basically, does Apache2 work with PHP 100% or is it still recommend to use Apache 1.3.27? If it is still not recommended to use Apache2, why? Because the server doesn't work very well yet. There are issues in the filter api and you can't really uses a threaded mpm as many of the 3rd-party libraries that are commonly linked into PHP are simply not threadsafe. The first issue can be fixed, the second issue is handled by only running Apache2 in prefork mode which makes the server look like Apache1. If you have to run Apache2 looking like Apache1 the benefits are minor, so the motivation for people to put a whole lot of effort into fixing issue #1 is minimal. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That's the kind of answer I was looking for. If I understand correctly PHP will not work correctly because some parts of it are not thread-safe. No, you didn't understand correctly. I specifically said the thread safety issues were in 3rd party libraries and not in PHP. This is not going to be solved anytime soon since it isn't really something we can fix. We can hack around it and add mutexes and stuff to protect ourselves from broken libraries, but in the end that just brings us closer to the non-threaded model that we already have with Apache-1.3, so there is very little motivation to even go through this bit of pain. Why exactly are you asking? Is there some feature in Apache2 that you need that is not available in Apache-1.3? -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Sorry, I thought by 3rd party libraries you meant libraries that PHP is dependent upon. Do you mean libraries used by PHP or Apache. And if these are libraries used by PHP, do you mean library that as in the multi-byte library (i.e. libraries that add functionality to PHP), or do you mean C libraries used when compiling PHP. Common libraries such as gdbm or c-client, for example. So this boils down to Apache2 using threads and PHP not being thread-safe? No And the reason that PHP is not thread-safe is that some 3rd party libraries PHP used are not thread-safe. No If they are libraries used to compile PHP, I would assume that Apache2 must have faced similar issues when going from a forking model to a threaded model? Why? Apache by itself doesn't need to talk to anywhere near the same number of 3rd-party things that PHP commonly talks to. #2 Is there progress being made towards having PHP work with Apache2. And who is working on this (if not the PHP team). Nobody really is. And I don't see this changing until there are some really compelling features in Apache2 to warrant the massive effort it would take. And yes, a working perchild mpm may be that compelling feature, but we don't have one of those. All of this stuff is available by reading the PHP and Apache dev lists, by the way. They are archived and not that hard to find. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] question about 'register_globals' setting
Thanks for your response but I don't think this is what I was asking; could be wrong though. I re-read your post and, of course, you are right. I mis-read it! I have heard of this Back button and data missing and I'm sure its come up before, but I don't remember the answer. I can only suggest looking in the archives, I'm afraid. This doesn't have anything to do with PHP. Whether or not a form will be populated or not after hitting the back button completely depends on whether or not the browser decided to cache that page or not. By default, a page served up by PHP will not be cached. You can make it cacheable by sending an appropriate cache-control header. However, in this case I think you said that the page was not even a PHP one, just static HTML in which case it should have gotten cached. Have a look at the HTTP headers the page generates. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] question about 'register_globals' setting
I'm using I.E. 6. I noticed that register_globals was set ON in my php.ini file so I changed it to OFF in as per the security warning. I've noticed a side effect. When I submit a form via POST and then go back from the results page, my form has been cleared, i.e.., as if the page has been reloaded. Is this a normal effect of setting register_globals OFF? Is there a way to continue caching? This should in no way be related to register_globals. -Rasmus -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
