Seriously.... If your apps are still being used in 2038 ... WOW!
This is an issue that will more then likely be well resolved LONG before
2038...

a 64bit unsigned int is best, but that would only work properly on 64bit
arch. For 32bit users, making it unsigned is the best option for now,
and I suppose that by 2038 there will be another option.
As far as I am concerned, this discussion is a discussion for the sake
of discussion. If I am still using the same apps that I use today in
2038, I will officially rethink my usefulness as a human being :)

Another possibility...
Port the Date object implementation from ECMA/Javascript.
It has a range of +/-8.64e15, or Tue, 20 Apr -271821 00:00:00 GMT to Sat, 13
Sep 275760 00:00:00 GMT.
You know...just to have a little extra time to find something else. ;)

i put "i think" only because im not 100% on the implementation, though i
know it has something to do w/ 64-bits; and it does seem to support a
massive range of dates on a 32-bit system. and also, there is good reason
to use it, if for example you have dates that are prior to dec 13, 1901.
the standard date() stuff chokes on anything earlier than that. and even
now, i have dealt with applications doing date arithmetic that spilled over
2038, breaking existing logic.
php > echo `uname -p` . PHP_EOL;
AMD Athlon(tm) XP 1500+
php > echo date('M-d-Y', -5555500000);
Dec-13-1901
php > echo date_create('@-5555500000')->format('M-d-Y');

as far as im concerned ive committed to using DateTime ever since i learned
of its superior internal implementation. that way i dont have to deal with
silly bounds related limitations in my date time calcs, ever (practically
speaking) :D
except of course those introduced by umm, human error ;)

It matters nil. We're all dead anyway. There's indisputable
evidence that "Crisis 38", as I've dubbed it, will be man's doom.

You may want to try this MIME parser class. It can parse the e-mail
messages of any size and optionally save the attachments to files in a
directory of your choice.
http://www.phpclasses.org/mimeparser
If want to parse messages retrieved from a POP3 mailbox, you may also
want to use in conjunction this POP3 class which comes with a stream
wrapper that lets you access messages in the POP3 mailbox as if they
were files. You can use file names like this: pop3://pop.server.com/1 .
http://www.phpclasses.org/pop3class
When used in conjunction, these two classes allow you to extract
attachements from messages of any size without exceeding your PHP memory
limits.

Yeah, after reading some about it yesterday and using it on some
sites, I like that it sort of simplifies some things for the end
user... it really fits sites like social networking stuff well.. I am

though for repeat visitors though... which is what I want to make it
easy& convienent for those repeat customers

Hi Guys,
We have a project where by we have a map in ai format (vector format). What
we want to do is to programmatically come up with a solution that say on the
map there is a restaurant at a certain location, that we can zoom into the
map on that specific area.
I really am not sure where to start. I guess image maps arent going to work
are they?
Should I be using the GD library for manipulating the images and doing
zooming? Also will the ai format be supported?
Please guys, any tips, links or help is appreciated.
TIA

Angelo,
You will need a specialised solution for this, like UMN Mapserver with
PHP/Mapscript. If you need some real, local, help, mail me off list, and
I will see about you guys paying me to do this for you (at SA prices) ;)
Seriously though, you won't get what you want with GD...

I think doing something like this with GD is nearly impossible.
But you could import the vector image in flash/flex. Draw an invisible
grid over it to create some sort of long / lat coordinats.
Or maybe just move to the google / yahoo map API's.

Hi,
I have this Apache server with mod_vhost_alias and set /home/pages/%0
as the VirtualDocumentRoot
In /home/pages/gamito.foo.com I have a index.php file. This generates
the http://gamito.foo.com URL.
Also, I have a /home/pages/fckeditor with FCKeditor. *This is not
defined as a subdomain in the DNS*
I need to include in my index.php the file /home/pages/fckeditor/fckeditor.php
I have:
@define('FCKEDITOR_BASE', dirname(__FILE__));
require FCKEDITOR_BASE . '/../fckeditor/fckeditor.php';
But no good, Apache says it can't find the file:
/home/pages/gamito.foo/fckeditor/fckeditor.php
So, there's a "gamito" hanging wrongly in the request.
How can I solve this ?
Any help woud be appreciated.

The Problem:
The code above works fine in sense of syntax!
bg.png acts as a transparent border for
14416fed5d4f78.jpg to keep the size of bg.png
and not the size of 14416fed5d4f78.jpg so it
doesn't blow up 14416fed5d4f78.jpg. However, the
image comes out black/white and has lost its
color!
I looked all over Google and I've found nothing
so far that's functional to give the new created
png file the correct colors as the original
14416fed5d4f78.jpg. I figure that I'm missing
some small elements to the process of creating
the png
Anyone have any ideas, pointers, advice, or
correct solution to make this possible?
Travis:
Try this:
$original=imagecreatefromjpeg("mydog.jpg");
$watermark=imagecreatefrompng("copyright.png");
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopy($original, $watermark, ($osx-$wsx)/2,
($osy-$wsy)/2, 0, 0, $wsx, $wsy); //center
imagepng($original, "trans.png");
The code works here:

I always jump right in and use the computer to design stuff. I never

anything like that. I just don't work that way.
I don't do much of that either unless I want to sort some complex things
out that aren't easy to visualize in my head. When I say 90% of your DB
should be designed before you start writing code... well, I usually
thinking about the create statements (I guess some people might call
those code), not drawing charts :)
Occasionally I scribble down ideas I want to include, but normally I
just go right to the keyboard and outline what I want to do in the
comments of the code. I fill in the code later.
In school, my teachers wanted flow-charts with symbols on them -- but
considering we only had rocks to program with (i.e., one symbol),
there was not much difference between the flow-chart and the program.
So, I bypassed the design and went straight to programming. Old
habits die hard.

I am having issues compiling php5.2.3 with Sybase 15. After much
troubleshooting, I was able to compile it with sybase12.5. But since we are
upgrading our system to Sybase 15. I need php5.2.3 to run with this version
of sybase. During my web search I found out that the library files php
uses/calls are different to the ones in Sybase15.
The article is from the bugs.php.net site:
http://bugs.php.net/bug.php?id=36516
I also followed a few suggestions regarding sybase directly from the php
site i.e.:
http://us.php.net/manual/en/ref.sybase.php
But none of the suggestions in the page above got me any results. If any one
else has any ideas/suggestions as to how to get php working with the new
Sybase/OCS-15_0 library files, it will greatly appreciated.
Thanks.
Lorena.

I need to determine if a file is truly deletable by a php script, Deleting permissions seem to be
the same as writing, they probably have the same criteria.
is_writable() seems to virtually useless in most cases. It doesn't take into account the directory
ownership/permissions; which, best I can tell, is the real determining factor.
I've resorted to having to determine the directory's ownership and then compare the directory's
rights with the owner's and then the other ['world'].
E.g., Assume my script was loaded with ftp, so it's ownership is the site-name, and I want the scrip
to be able to determine if it can delete a file. Thus, the file in question must have its "other"
permissions include write.
Surely, there must be an easier way.
Thanks, Al........

Hi,
Maybe this is what you need:

You are missing the point of my question. I don't have a problem reading the permissions. They do
not solely determine whether a file can be deleted.

You're not writing to the file, you're unlinking it from the
containing directory, so it's the directory's permissions that matter,
not the file's.
All you really need to do is check that the directory is_writable()
is_writable(dirname($filename));

If it's not, what else can? I got curious.

Dear PHP List,
PHP 5, Apache2, MySQL 5, running on Ubuntu, viewing & deving with
FireFox and Konqueror (Linux).
I am building a site with multiple tools and want to pass variables
throughout them all. Before, I was passing variables using <hidden> HTML
Form tags, but the site has grown too large for this tactic, so I went to
using $_SESSION. However, when I started using $_SESSION, my site loads 3-5
times slower then before. A page that queried MySQL and built itself in 3-5
seconds was now taking 15-20. While more has changed then just $_SESSION,
it is really the only significant difference.
Is $_SESSION slowing down my site? Is there a faster alternative to
global variables then using $_SESSION? Are using regular cookies faster?
Any help is appreciated.
Thanks,
Scott

How are your sessions implemented? Are you using the stock PHP session
functionality or did you cook your own solution? I can't see the stock
PHP solution adding anything more than a split second to your page time.
The exception being when it performs cleanup. Cleanup should be
relegated to a cron job. Have you added anything new to the database?
new query perhaps on a large table that doesn't make use of indexes?
Small changes can have a bigger impact than large changes depending on
what exactly changed.
Cheers,
Rob.

Did you add any includes and are they include or include_once or require VS.
require_once?
I found stress tests that show that an include is faster then an include_once
and so removing the _once from includes and requires will speed up your site.

Hey,
<clip>
$tag_regex=array(
'/\<p(\s*)\>(.*?)\<\/p\> /si' => "$1",
'/\<(\s*)(*.?)class\=(*.?)\>(.*?)\<\/(*.?)\>/si' => "$3"
);
$paragraphs=preg_replace(array_keys($tag_regex),array_values($tag_regex),$page);
I am not sure what tag is that you mean on <class="something">, but in this
RE .. it should capture any <p> tags (the first element of the array) and
any tags (the second element of the array) that has attribute class on it.
</clip>
Thanks for replying!
Sorry, a bit of a typo there, i meant <p class="something">
I ran your regex but got this warning:
Warning: preg_replace() [function.preg-replace]: Compilation failed: nothing
to repeat at offset 8 in C:\xampp2\htdocs\ezee\tests\para_regex.php on line 25
I think I ran it wrong, because although i have passed $page i dont know where
to pass the replacement texts...
Can you give me an example on how to run this or an explanation?
Thanks!
R
