put this at the top of each page and see if you get any undefined
variables warnings as it may be a problem of variable scope

In the last pair of examples where it fails, you know you are first
assigning the value of $Data['ID'] to the $_SESSION['CategoryID'] and the
over-writing that value with the value of intval($Data['ID'])? Why are you
assigning $Data['ID'] to it if you are going to overwrite it? If those
other tests work then I doubt that it is a session problem. I'd
double-check to make sure that $Data['ID'] is holding a reasonable value.

Subject: [PHP] session var puzzle
Dear list,
I am sorry for the second posting, but this is going
to drive me to drink something other than lattes!
I have one page, index.php. when it calls mod_sub, a
directory type of page is printed. Here I am trying
to set a session var of the most recently selected
category to allow the user to return the to same place
in the directory.
when I do this:
$_SESSION['CategoryID'] = 230; in mod_sub
then in mod_profile:
print($_SESSION['CategoryID']);
will print 230
when I do this:
$Tmp = 230;
$_SESSION['CategoryID'] = $Tmp; in mod_sub
in mod_profile:
print($_SESSION['CategoryID']);
will print 230
BUT, when I do this:
$_SESSION['CategoryID'] = $Data['ID']; in mod_sub
$_SESSION['CategoryID'] = intval($Data['ID']);
in mod_profile:
print($_SESSION['CategoryID']);
will print '' and 0
I am setting several other session variables
throughout the code without any unexpected behavior.
I have even tried changing the index to something odd
in case I am resetting 'CategoryID' somewhere and
forgotten it. But no matter what I try, once I set it
"= $Data['ID']" I get the odd result.
BTW, if I print $_SESSION['CategoryID'] from mod_sub
right after setting, it holds the expected value.
This is really frustrating, I must be missing
something basic about the way session vars can be set.

Okay, what you can do is try use an .htaccess file (providing your host
allows them) to make the PHP engine parse .html files.
Create a file titled ".htaccess" with the following contents:
AddType application/x-httpd-php .php .php3 .html .htm
Upload it to the same folder that the .html file is in, and see if it works.
(Oh, and if you are using WS_FTP LE, be sure to add '-al' in the white
box on the right [Remote] vertical line of buttons so that you are able
to view the .htaccess file in the folder once uploaded.)
Cheers,
Andy

It's already been mentioned, but you do need to ensure you are using a
.php extension on the file. Also, forgive me if this has already been
covered, but are you sure the server even supports PHP?
Try creating a new file with:
<?php
phpinfo();
?>
And save it as something.php, check and see if it returns a table full
of information or not.

Greetings everyone :
Having a hard time with this one. I have a multi-dim array
$foo[$x][$y]['key'], where $x and $y are numeric. Here is some sample data
[ snipped ]
I need to filter the results so that I get the latest expiry date for
each product. The expires field actually contains a timestamp. So for
the sample array above, the resultant array would have only keys 0 and
2, filtering out all the rest. There are around 180+ main entries, with
any number of sub entries, but each sub entry has the same four keys.
Any ideas? Getting a rather large headache mulling over this.
Hi,
as your structure is always the same you could just loop through all
elements and subelements and use unset() to remove the unwanted array
elements:
foreach ($foo as $key => $value) {
foreach ($value as $subkey => $subvalue) {
// put your check logic here
if ($foo[$key][$subkey]['expires'] == '') {
unset($foo[$key][$subkey]);
}
}
}
What do you think?
Well this is what I have right now, but the problem is the logic which
checks to see for each domain which is the last expired date. I have
three nested for loops right now, and not getting anywhere :(

Maybe it works if you put the expires value in a seperate array, sort it and
then you can get the key of the first one and use unset():
foreach ($foo as $key => $value) {
$tempArray = array();
foreach ($value as $subkey => $subvalue) {
// add expires value only to the temporary array for
sorting
$tempArray[$subkey] = $foo[$key][$subkey]['expires'];
}
// sort array by value descending
arsort($tempArray);
// get first (and therefore highest timestamp) key/value pair
$firstEntry = each($tempArray);
$notneededSubkey = $firstEntry['key'];
// now unset the array value with the not needed subkey
unset($foo[$key][$notneededSubkey]);
}
Have not tried it but may work. Hope you see my point.

Well, it does some sorting, but not quite what I'm after :(
I've managed to get the list so that all the (sub) entries are sorted in
the correct order. Now its just a matter of finding the highest expire
date for /each/ domain, and delete the other entries for that domain.
So, in the end, all that's left is one entry per domain, with its latest
expire date.
Hopefully this makes it a bit clearer.

OK, so it's just the other way round - I see. Instead of deleting the entry
with the highest expiry date we delete all the others:
foreach ($foo as $key => $value) {
$tempArray = array();
foreach ($value as $subkey => $subvalue) {
// add expires value only to the temporary array for
sorting
$tempArray[$subkey] = $foo[$key][$subkey]['expires'];
}
// sort array by value descending
arsort($tempArray);
/* new stuff starts here */
// remove the entry with the latest expiry (the first array
element)
array_push($tempArray);
// now unset all remaining/not needed entries
foreach ($tempArray as $tempKey => $tempValue) {
unset($foo[$key][$tempKey]);
}
}
By the way, isn't there a way to filter this stuff BEFORE or WHILE the whole
array is created?

Thanks for the help. I'll give that snippet a try and see what comes out.
The array is a result of a rather nasty SQL statement running against a
database (which I didn't design). Unfortunately, the way the database is
designed, its very difficult to extract the domain information.
I am in the process of rewriting the entire thing as a Java application,
hopefully that will make things a bit clearer, since I'll also be
refactoring the database schema.
Many thanks,
Burhan

What browser are you using? I've seen this topic come up before, and it
tends to be an issue with the client rather than the server. The client I
use happens to avoid sending the session cookie from a new window, so this
doesn't generally happen to me, while other clients default to sending the
session cookie.
BTW - cool site.

Hi Thomas,
Thanks for the correction.
My current undertanding is that zend-acelerator, phpa, turck-mmache and
apc do not
support PHP5.0rc1 ? Is there any accelerator that does ?
Thx dave

uhm, afaik the "optimiser" is not an accelerator, more kind of a loader for
encrypted files.
You would have to use the zend-accelerator, phpa, turck-mmcache, apc or similar
products.

Although Turck MMCache doesn't yet officially support PHP5, it works (very
well here). If your able to test it with PHP5 and send bugs when/if you get
any problems, then it might be ready sooner. :)

Hi David,
I'm not quite sure if its worth the trouble to officially support
a php-version which is not yet stable.
I remember that, at least, turck-mmcache has unofficial support for php5.

Basically they run through the whole text and if they found something
that was translated they made a hash and replaced the actual text with

when all occurrences of translatable elements were found they ran

I found that to be quite an ingenious way of doing it ...
Then again it might have misread/misinterpreted the code :)

Sunday, April 18, 2004, 10:08:51 PM, thus was written:
I can't figure out how to do this.
I've four different methods for changing a piece of text into a hyperlink.
the text:
[link=www.hotmail.com]hotmail[/link]
[link=http://www.hotmail.com]hotmail[/link] www.hotmail.com
http://www.hotmail.com
what it should become (offcourse in HTML it will change to a real
hyperlink):
<a href="http://www.hotmail.com"; target="_blank">hotmail</a> <a
href="http://www.hotmail.com"; target="_blank">hotmail</a> <a
href="http://www.hotmail.com"; target="_blank">www.hotmail.com</a> <a
href="http://www.hotmail.com";
target="_blank">http://www.hotmail.com</a>
i've got this regexps, at this point there are two different ones and I
would like to combine them (not really necessary):
1.
$text = str_replace("[link=http://";, "[link=", $text);
$text = preg_replace("/\[link=(.+)\](.+)\[\/link\]/U", "<a
href=\"http://\\1\"; target=\"_blank\">\\2</a>", $text);
2.
$text =
preg_replace("!(((http(s?)://)|(www|home\.))([-a-z0-9.]{2,}\.[a-z]{2,4}(:[0-9]+)?)((/([^\s]*[^\s.,\"'])?)?)((\?([^\s]*[^\s.,\"'])?)?))!i",
"<a href=\"http\\4://\\5\\6\\8\\9\" target=\"_blank\">\\1</a>", $text);
// I copied this one, maybe someone knows a better one?
the problem is that it's replaced a second time resulting in this:
<a href="<a href="http://www.hotmail.com
target="_blank">>http://www.hotmail.com</a>]hotmail[/link] [link=<a
href="http://www.hotmail.com"; target="_blank">www.hotmail.com</a>"
target="_blank">>hotmail</a> <a href="http://www.hotmail.com";
target="_blank">>www.hotmail.com</a> <a href="http://www.hotmail.com";
target="_blank">>http://www.hotmail.com</a>
the last two (without the [link=] part) are working
