Hello there,
I can't figure out why there are some headers set while i don't set

The following headers are sent to the browser.
-Expires: Thu, 19 Nov 1981 08:52:00 GMT
-Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0
-Pragma: no-cache
All those i didn't set my self.
Does PHP set these or something?
maybe it was php (check your session settings and read the relevant
parts of the manual
regarding session related headers)
maybe it was a piece of 3rd party code.
may it was 'something' ;-)
most likely it's the session extension doing this.
And you are right again :).
Thanks again.
This was a real pain in the ass.
Because IE didn't sent the If-Last-Modified and/or if-none-match if
one of those headers are sent.
Thank you.
Thx in advanced.
Well it seems its working kinda.
Now i have a problem with the ETag.
what are you using this header for?
I Use this header to check if the content of a file has changed.
This because the content can be variable. But is static most of the time.
I Compute an MD5 of the content, and add this to the ETag.
Normally a browser sends an HTTP_IF_NONE_MATCH back if it has an ETag.
If this gets send back, i compare them and if they are the same, they get en
304 Not Modified back.
Now Internet Explorer doesn't send this back when the content has been
compressed (gz_handler).
This because the Vary header has been set or something.
This is a bug in IE, and probably fixed in IE7.
Internet Explorer seems to forget this when the content is compressed.
This because of the Vary header apparently.
Is there a fix for this?
Or a workaround?
yes. but your no longer in the realm of php (I believe)
this is something you should tackle at the webserver configuration level...
on one of the machines I run the (main) site has this in the config (its
apache):
# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following
# workaround to get the desired effect:
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
# Don't compress images
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \/image\.php no-gzip dont-vary
# Also don't compress PDF and Flash-files 17-01-2004 MM
SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.swf$ no-gzip dont-vary
# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
now I'm not saying these settings will work for you - the site in question
runs behind an instance of Squid configured as a reverse caching proxy - which
complicates matters somewhat - but it might give you an idea.
I have checked this also, and it came up with nothing. :(.
It now seems that i have to check if i am dealing with Internet Explorer or not
within PHP.
And then if it is IE i don't compress the content.
Anyway,
Thank you very much for your help :).
If you have any idea's left :D.
Kind Regards,
Mathijs.
Thx.

freaking lightbulb moment for me!!! see how it pays to help people - you never
know
when you might get slapped in the face with some new knowledge :-) thanks!
that said I wonder whether generating the dynamic content, buffering it, using
the buffer to
generate a md5 hash and then checking that is any faster than just outputting
the
generating content regardless? or is this purely a tactic to reduce bandwidth?

LoL. And no problem.
Um yea it's an bandwidth saving tactic.
This because the website has big traffic.
And it is mostly the JS and CSS files that are eating everything up.
If i compress them it saves a lot of bandwidth.
I Just discovered this problem with IE and the ETag :(.
I use Opera and Firefox my self. But didn't really checked this caching in IE.
And most of the users still use IE.
I Think i have to weigh the features.
The content isn't going to be changed that much.
Only when someone changes the language or if i change some constant values.
So i think i go for this solution since there is non so ever to fix this for IE.
I am going to check the user-agent.
If it is IE then i am not going to gzip the contents.
Everything else then IE will get the gziped contents.
This way the ETag gets send back, and i can respond with an 304 if it still is
the same.
This should save bandwidth also. And it will only send out an un-compressed
version just once.
And it will resend the content when it is changed (Which i think won't happen
that much).
Again, thanks for you thoughts :).

Antonio:
The reason why you are not seeing the characters is that they are being
grabbed-up by the browser as html code. In other words, you are injecting html
into your web page.
Take a look at this:
http://www.weberdev.com/htmlentities
Now, pass your content through this function and then display.

Subject: [PHP] Problem installing php
Date: Tue, 11 Jul 2006 12:04:18 +0200
From: Ruben Rubio Rey <[EMAIL PROTECTED]>
To: [email protected]
I have a problem when installing php. I have tried with different
versions of apache (2.0.55 and 2.0.58) and php (5.1.4 and 5.1.2).
The problem still there (Same error in different versions)!!!
Note that I had installed apache 2.0.58 and php 5.1.4 before on this
server. Problems began when tried to add -with-pspell --with-openssl at
configure. ( I installed aspell). When I tried it, i was no able to
install php again.
Any ideas or workarrounds will be appreciated.

Look in task list of what needs doing, and do some of them.
Make sure only one job is done at a time, or whatever race conditions

I've done projects both ways, and always end up frustrated with the

Hi,
Something strange and dont really know what to expect so was hoping you more
experienced PHP 5 people can help me out.
We have been given a development server thats running php5 with MySql Client
API version 5.0.22 (didnt know there was one that high)
the problem is, we have to develop on this and then when its done the app will
be moved to a php 4 final server...
I have been reading and i see that there are some php4 functions that act
strange on php5 (like strpos)
are there any other things I should be aware of?
If you think it would be too much of a hassle, do you think i should request
the admin to install php 4 instead and scrap this installation?
I have also seen many sites having php4 and 5 on the same machine, this is a
windows server, is there any easy way to do that here?
Thanks!
Ryan

btw which minor version of php5 your running is important ... plenty of things
have changed in [semi] breaking ways
between minor php5 versions.

what's wrong with strpos() in php5? are you perchance using multibyte strings
without using the mb_string
function overloading stuff?
> are there any other things I should be aware of?
the fact that objects are always references in php5 and in php4 you have to use
'&' everwhere to
make sure your always talking to the same object (using the '&' notation in
php5 will give you NOTICEs or WARNINGS
depending on the minor version)
that and a million other little things like certain functions not being
available :-)

YES. *at the very least* it will be a pain to dev on php5 and go to production
on a php4.

Here's to being bored on lunch. :)
Now to add my two cents to the convo:
I don't see a problem with storing images in the DB IF they aren't
going to be continually accessed that way. For example say you have a
script that lets a user upload an image and creates a small, medium,
and large view out of it. Stick the original in the Db and then make
your 3 sizes on the fly and cache the output so they are not
continually created. This way you could down the road re-do all the
sizes if you go through a site redesign or the client chooses they
want them 450 instead of 400. =)

The time taken per request, though (and that's about all we can get with
a concurrency as low as 5) doesn't tell us much. We also don't know
exactly what the PHP code is doing, how it does it, how your database is
organized/indexed/accessed, if you have any PHP accelerators installed
(Normally the PHP script would be reconverted to bytecode every
execution), etc.
Additionally, your test isn't really MySQL versus filesystem, it's
PHP+MySQL versus filesystem. Perhaps a more useful comparison would be
PHP+Filesystem versus PHP+MySQL. As in, the same PHP script for both
benchmarks, except one copy uses file_get_contents and echo (Closer
match than readfile, since MySQL would require loading the file into
memory) and the other uses MySQL. This would be a closer match that
would tell us how much latency is induced by the actual database itself
rather than PHP and loading stuff into memory.

I have an array that i would like to sort and reorder based on a simple
critera. I already order the data but I would like to break the data now
into sections by customer id, so one customer has 5 things and another
customer has one. How can I do that with an array.
$data = orders($id,$status);
$c = count($data);
for($i=0; $i<$c; $i++) {
$orderid = $data[$i]['orderid'];
$customerid = $data[$i]['customerid'];
$name = $data[$i]['name'];
print $orderid.' - '.$customerid.' - '.$name.'<br>';
}
What it is currently is all the orders are ordered by the customer number,
however I would like to group it a little nicer on the output.
Current:
1234 - blah blah blah - Y - 3, 01234
1235 - blah blah blah - N - 6, 01234
1236 - blah blah blah - N - 6, 01234
1237 - blah blah blah - Y - 6, 11256
1238 - blah blah blah - N - 6, 22589
1239 - blah blah blah - N - 6, 22589
1240 - blah blah blah - Y - 6, 22589
1241 - blah blah blah - N - 6, 22589
Would like:
01234 - The Customer 1
1234 - blah blah blah - Y - 3
1235 - blah blah blah - N - 6
1236 - blah blah blah - N - 6
11256 - The Customer 2
1237 - blah blah blah - Y - 6
22589 - The Customer 3
1238 - blah blah blah - N - 6
1239 - blah blah blah - N - 6
1240 - blah blah blah - Y - 6
1241 - blah blah blah - N - 6
Anyway I can do that?

Ok I understand your method now. your code does not match your output. how
would your print line produce that , $customerid ?
anyways...
$data = orders($id,$status);
$c = count($data);
$currentId;
$n = 1;
for($i=0; $i<$c; $i++) {
$orderid = $data[$i]['orderid'];
$customerid = $data[$i]['customerid'];
$name = $data[$i]['name'];
if($currentid == $customerid) {
//Continue current customer group
print $orderid.' - '.$customerid.' - '.$name.'<br>';
} else {
//Begin a new group...
$currentId = $customerid;
Print("Customer ".$n");
$n++;
}
}
I'm kind of headed out so its a bit rushed and the example above wont work
as given but you get the idea from the two comments I added...

I stumbled accross the following page while RTFMing:
http://php.net/manual/en/wrappers.ftp.php
very nice, it enabled me the come up wth the following to lines (nice and
compact!):
$context = stream_context_create(array('ftp' => array('overwrite' =>
true)));
$retval = file_put_contents("ftp://{$ftp_user}:[EMAIL
PROTECTED]:21/{$filename}", $xml, LOCK_EX, $context);
BUT this leaves me with the problem of determining what went wrong if the
file_put_contents() call
fails. did the connection fail? did the login fail? did the write/upload fail
(and why)?
using the std. ftp functions it's [obviously] alot easier to determine at which
point the failure
occured. can anyone confirm I'm on the right track by trying to set
'notification' [stream]context
parameter?

I've noticed a 'feature' that seems to be causing me some pain.
When a user logs in, we store various pieces of info and their user class in
a $_SESSION variables.
This includes a flag saying that they've ben authenticated.
I would expect that if I 'rm -rf /tmp/sess_*' that the user would get
prompted to re-login (since the flag is not set).
However what actually happens, is that PHP silently just re-creates the
session with a new unique identifier but with all the same data in it. GRRR.
How can I force this to NOT happen (either via php.ini or via some function
or directive call in each page load)?

Hi,
Something strange and dont really know what to expect
so was hoping you
more experienced PHP 5 people can help me out.
We have been given a development server thats running
php5 with MySql
Client API version 5.0.22 (didnt know there was one
that high)
the problem is, we have to develop on this and then
when its done the
app will be moved to a php 4 final server...
I have been reading and i see that there are some php4
functions that
act strange on php5 (like strpos)
are there any other things I should be aware of?
If you think it would be too much of a hassle, do you
think i should
request the admin to install php 4 instead and scrap
this installation?
I have also seen many sites having php4 and 5 on the
same machine, this
is a windows server, is there any easy way to do that
here?
Thanks!
Ryan

It's silly to have two different environments like that.
Either code the thing in PHP4. or upgrade the production environment to
PHP5.

Unless there is some specific reason that you need this code to run on both
php4 and php5, then inform your boss/admin that the idea of developing on
php5, to deploy on php4 is nuts. If they disagree inform them that they are
personally nuts( tell them some guy on the internet said so ).
It may be possible to develop php5 code in a php5 env, if you are intimately
familiar with the differences between php4 and php5, but if you're that
familiar with PHP, then you're worth more than a half-ass software creation
enviornment.
Basicly it's a catch22 if you're good enough to be able to cope with this
enviornment, you shouldn't have to.

Hello all,
This is the first time I have posted an issue to this forum, so please
excuse in noob questions or statement. I am trying to create a table
from a string that created by a DESCRIBE TABLE query... this is the
generated string:
CREATE TABLE 'users' ( 'username' varchar(120) NOT NULL primary key,
'password' varchar(64) NOT NULL, 'level' int(11) NOT NULL DEFAULT '0'
)
then I use the statement:
$db is a PEAR DB object that has been set up with my database access
info and connects to MYSQL.
$stmt = above create string.
$db->query ( $stmt );
for some reason it is not creating the desired table. Can anyone give
me a solution or a reason why the above situation would not work. Just
to clarify that my Database info is correct I was able to generate the
create string from a DESCRIBE TABLE query so the connection works and
is valid and I have CREATE rights.

If all else fails, use phpAdminMySQL to set up your tables. I seldom program it.
