That's interesting - it also started happening for me after installing
PHP 5.0.3. But I have reverted to 4.3.10 for now, and I can't see how
installing 5.0.3 into an entirely separate directory can break my old
php install. Hmm..
Incidentally, are you using Pear at all?

No session identifier is generated at this point. This generation only

Yes.
Are you sure you need a new session identifier?

I'd have to do some tests to find out, but you might want to set
$_SESSION to attay() rather than just unset it, but these might have
essentially the same behavior (e.g., memory is freed but not overwritten).
Hope that helps.

WILD GUESS
You've got Apache configured to do a reverse DNS lookup to see the domain
name of the visitor... Only now it's trying to find a domain name for
192.168.2.100 which is not in your /etc/hosts file and ain't gonna show up
in DNS records any time soon...
Note that I don't really understand any of this proxy stuff you've done.

Many thanks for all the answers.
I've checked that I was saving the right file (I even think about it
!), and even if I'm using Templeet (sort of smarty http://templeet.org
) i've disabled all cache, and this code is only PHP not
template-language.
I've checked the error.log, and it just said that the file does not
exists (which is normal, the page is generated when it's missing, by
Templeet, thus proving it's not using a cache). Now, i've put the
class definition inside by PHP file, (I do not include it anymore with
include ''), and it just hang with the error.log saying that it
exhausted all memory.

To this you might also add an MD5 hash to check for authenticity,
depending on what you're doing with that incoming data that you're
unserializing (consider an client who sends you a serialized array that
you didn't intend). You'll also want to encode the serialized data with
htmlentities:
$serialized = serialize($testArray);
$hash = md5($serialized . "my secret phrase");
echo '<input type="hidden" name="serialized" value="'.htmlentities($serialized).'">';
echo '<input type="hidden" name="hash" value="'.$hash.'">';
then on the receiving end:
if ($_POST['hash'] != md5($_POST['serialized'] . "my secret phrase") {
// the hash doesn't match up, consider the data unusable
} else{
$testArray = unserialize($_POST['serialized']);
}

Hello,
Please can someone tell me how you pass arrays between PHP pages.
I have tried something like this and have tried many variations of this but
nothing working yet ;
Page 1
$testArray[0] =Apple;
$testArray[1] =Banana;
$testArray[2] =Peach;
echo "<INPUT NAME = \"kcompany[]\" TYPE = \"hidden\" VALUE=\"$testArray\">";
Page2
echo $testArray[1];
On different variations of this I keep on getting 'Array' when I to return the variable on the second page
Many Thanks.

Because you only have 3 elements in one or more of those arrays.
Remember, index 3 is the 4th element.

Take that attitude back over to the Perl newsgroup. One of the joys of PHP
has been a non-techhead, non-stressful, Open Source spirit of teaching and
helping others, which in turn helps PHP grow and flourish.
I'm polite, but seems that the original poster took no effort on their
part to try and solve the problem first. I'm polite to people that try
and solve the problem first, before coming to others for help.
The original poster could have done any of the following things:
1. Simply type "mail" in the search box on the php.net website, which
would have taken them to the section titled "Mail Functions", where the
first line reads " The mail() function allows you to send mail." When
they would have clicked on mail(), the would have seen examples on how
to send an email.
2. Simply typing "sending email php" in Google would have gotten them a
lot better results.

One line of code?

Hi,
I found this beautiful piece of code on the php site which make a
proportional thumbnail, problem is its only working with JPEG files...and
not with GIFs, can someone please help me convert it to GIF too?
I tried but got a bit confused as there are no functions that are equal to
"imagecreatetruecolor" that is in the below script.
The below script works perfectly for jpgs:
<?php
// The file
$filename = 'test.jpg';
// Set a maximum height and width
$width = 200;
$height = 200;
// Content type
header('Content-type: image/jpeg');
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
if ($width && ($width_orig < $height_orig)) {
$width = ($height / $height_orig) * $width_orig;
} else {
$height = ($width / $width_orig) * $height_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height,
$width_orig, $height_orig);
// Output
imagejpeg($image_p, null, 100);
?>
Beautiful, isnt it? Hats off to whoever wrote it and three cheers for the
online manual!

If your version of GD supports GIFs (which not all do), then it's almost as
simple as changing every place you see the string "jpeg" to "gif".
Look in the online manual for the image functions. You'll see reference to
the ones here (such as imagecreatfromjpeg()) and also ones for PNGs and GIFs
and a few others.
Just realize that when you are reading a file of a particular type, you need
to use those image<type>() functions... But in most cases they are
completely interchangable if you're passing paths to images of the
appropriate type.
Hope all of that makes sense :)

I believe all the imagecreatefromXYZ functions create a truecolor image
for internal manipulation...
Though I could be wrong, as GIF images do have pallet information within
them, and I supposed GD could be justified in using that to build a
256-color image...
At any rate, imagecreatetruecolor creates a "format-less" image -- It's
not a GIF, JPEG, TIFF, or anything, really. It's in an internal GD
format, and you can do whatever you want to it, and then output it as
whatever format you want.
> The below script works perfectly for jpgs:
As noted, just change jpg to gif everywhere, and it should work fine, if
your GD supports GIF.
Or you could even alter the script to determine the image format based on
its filename, then call the correct imagecreatefromXYZ and the correct
imageXYZ at the end.
Or, you could even use http://php.net/imagegetsize and IGNORE the
filename, and base your decision on what's actually *IN* the file, so when
some idiot renames a jpeg to ".gif" because they think that will make it a
GIF (yes, that really happens) then you won't get messed up.

Search engines do not generally index a page they can detect is
dynamically generated.
That means pages that have ? in the URL.
You can use $_SERVER['HTTP_PATHINFO'] to alter URLs to not have ? in them,
and they will get indexed by the search engines.
There are several on-line articles on how to do this.

PHPdig comes with extensive documentation and you are free to rewrite
the code so that the search engine does exactly what you want. But, you
have to be rather familiar with PHP. My own impression was that it is
easy (more or less) to do some basic configuration on the search
engine. When it comes to adopting the code for your own needs, so to
say, it is sometime necessary to do some extensive research on the PHP
manual.
However, Phpdig is capable of indexing dynamically generated pages (I
just tested it). To write a little script in order to update the index
when the pages content changed, shouldn't be a problem either.
Download the package and take a look at the source code.

Errrr.
Unix epoch dates start with the integer 0 representing midnight 1/1/1970.
Rumor has it that the authors of this standard are big Disco fans, but
they have only replied with "No comment" :-)
I dunno what you expected to get from 1966 in an epoch date, but it's not
kosher input, so there ya go.
The only work-around for getting pre-1970 dates is not using Unix epoch to
represent your dates.

This is pretty much a MySQL question, really...
But: There is a new-ish SQL_CALC_FOUND_ROWS constant you can use in your
query to get MySQL to tell you how many rows you would have gotten without
the LIMIT clause. You may be able to use that.

Probably.
But since you only told us "it gives me an error" and don't tell use
*WHAT* the error is, we really can't help you, can we?

Hmmmm. Actually, I *can* tell you that you shouldn't have FROM in there
twice. You've messed up your query something awful with that.

"else if" and "elseif" are not exactly the same, as the manual indicates
(and glosses over a bit).
The will behave the same, if everything is parallel, but there is a gotcha
when you start embedding nested if/else and if/elseif statements.
If I try to give an example, I'm sure to screw it up, as I never use "else
if" for this very reason.
But this is the same as in C, and I think any decent C textbook will
diagram for you exactly what goes "wrong" when you confuse the two.
If you're not sure of the difference, use "elseif" when the words appear
that close to each other, and you will most likely not hurt yourself that
way.
You only get burned, and that only rarely, if you use "else if" in my
experience.

Personally, I'd opt for working on the macro first, and making that as
clean and clear as you can, really thinking deeply on it.
Put it away for a day or two and pull it out.
Does it all still make sense?
Are you REALLY providing the best functionality for the most users as
quickly and efficiently as possible?
It's much too easy (guilty!) to start diving in and writing
code/functions/pages without reflecting enough on the big picture.
Course, you sometimes have the PHB breathing down your neck who will
accuse you of "not working" if you aren't typing code. Sigh. Time to
quit *that* job and look for another one.
PS I'm looking for a new job. :-^

+1 on pen and paper.
One approach that I liked (I forgot what book it was mentioned in)
involves using a whiteboard and post-it notes.
You put your entities on the post it notes, then draw flow lines on the
whiteboard. This way, you can easily move your entities around.
It really helps when ironing out workflow issues. For example, what
happens when a user enters the wrong password in a login form? Easy to
figure out by just moving around the sticky notes. Once you have your
flow dailed down, then its just a matter of copying it on paper and
finalizing it.

That sticky-notes + whiteboard helps with dynamic flowcharting a lot.

But you *WANT* the urlencoded into %40 so the email harvesters won't

It works just fine in all browsers except, like, AOHell 4.0 or something
like that.

The first most biggest thing wrong is that you aren't using the additional
arguments to exec() to find out what your output is, and if your command
generated an error.
For starters, I'm betting that at least one of the following is true:
whoami is not in the $PATH/$path of the PHP user.
whoami is not executable by the PHP user.
You'll never find out which unless you use the extra args to exec

But are they in the $path of webuser?
Use the full path to them if they aren't
exec("/bin/whoami", $output, $error);
if ($error) echo ("OS Error: $error.<br />\n");
echo implode("<br />", $output);

No, it tries to run them, and fails, and provides the error messages and
error number in the variables you aren't using :-)
Some days, I think the PHP Dev Group should just make those arguments to
exec() required.

hi! i'm trying to use the simple_xml functions to get an arrray of

The above output shows $sample_data->first_names->first_name as an
ARRAY in the first 2 print_r 's however when a print_r is run on
itself it shows it as a SimpleXMLElementObject.
Question is why the last print_r gives different information
compared to the other 2.
I also tried running
$key = array_rand($sample_data->first_names->first_name)
and it gives a warning message
"Warning: array_rand(): First argument has to be an array in
/home/yvb/work/practice/php/XML/foo.php on line 16"
any clue how do i use the
$sample_data->first_names->first_name as an array ?
thx.

And that's precisely what I did. The only reason why I only have
.htaccess in the top-level directory is that I don't have any directives
specific to one subdomain that the others shouldn't use and according to
the apache docs when requesting a file apache looks in every
higher-level directory for .htaccess as well.

I already contacted their support asking them to at least have PHP5
built as a module when they'll upgrade. I'm not to happy with their
support anyways, responses are fast but they've never told me anything I
hadn't known before asking them.
I've moved from trying to use HTTP based authentication-methods to php
sessions and html-form based authentication, it's much more configurable
especially visual-design-wise and wasn't half as challenging to
implement as I'd expected. Don't you just love when you teach yourself
something new and can use it to do what you want to, and it actually works.
Okay, enough chatting. I just wanted to thank you for your answers
Richard, very helpful and informative.
Cheers from germany, Roman.
P.S.:
> WILD GUESS:

Nope, tried dumping $_SERVER, $_ENV and $_REQUEST upon cancelling the
authentication, nothing useful in there. It says in a comment to the
manual that the authdata is in $_SERVER['REMOTE_USER'] and you can
either base64_transcode it (or whatever the function is called) or use
apache's ModRewrite but I can't confirm that, maybe the person that
suggested it was using apache2, in any case it didn't work.
