Don't confuse predation with predate :)

As far as I'm aware, eggs don't predate anything. How could they - they
don't have legs or mouths so couldn't eat anything if they could run to
catch it :-)
Oh yeah, what about Pacman?
But then again, eggs also "predate" Pacman too!
In a morphological sense, there are, and have been, egg-shaped
critters that prey on other critters. The microscopic world is filled
with them.

Not a bad article, but just speculation based upon the Geological
assertion that "The present is the key to the past." For most
things, it works reasonably well -- but, we don't know for sure.
For example, several hundred million years from now when mankind is
history and some alien paleontologist is looking through the rock
record and stumbles across the fossilized remains of a penguin, he
might speculate that these critters had to be the fastest animals on
earth to get those short wings to work.

Use curl_setopt() to let curl save the cookies.
Specifically you need these two options:

So after I recently upgraded from php4 to php5 I noticed that email

however those same email attachments work just fine if I hit the imap

Has anyone else run across this before? I've seen other bugs on different

Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (2)
FYI I did this to solved the problem but it didn't work:
http://webyog.com/forums/lofiversion/index.php/t1367.html the only thing is
that I'm running MySQL 5.0 (I have a my.ini not my.cfg) and I put the var
folder in the following dir C:\Program Files\MySQL\MySQL Server
5.0\var\lib\mysql. I also modified my PHP.ini to reflect new socket
location.
What really bothers me is that all was fine until yesterday and my AMP setup
for localhost works fine. Only when I upload to Webhost i get the socket
error
The only thing I did was add the following include file @ the top of all my
admin pages.
====================================
include file
<?php
session_start();
if($_SESSION['auth'] != "yes")
{
header("Location: AdminForm.php");
exit();
}
?>
//===========================================================
AdminForm looks like:

Also if I change the AdminFormVal.php beginning 'if' clause to $_SESSION
instead of $_POST, I mysteriously don't get the mysql.sock error. But script
does nothing when I do that of course.

AdminFormVal.php file looks like this:
<?php session_start();
if(isset($_POST['sight']))

include("connex.php");
$checkUnameQuery = "SELECT uname FROM admin WHERE uname ='$_POST[uname]'";
$checkUnameQueryResult = mysql_query($checkUnameQuery) or die("Can't

$rowResults = mysql_num_rows($checkUnameQueryResult);
if($rowResults == 1) //login name was found

AND pword ='$_POST[pword]'";
$checkUnameQueryResult2 = mysql_query($checkUnameQuery) or die("Can't

$rowResults2 = mysql_num_rows($checkUnameQueryResult2);
if($rowResults2 > 0) //password was found

I have a piece of code which uses curl to get a web page and puts it
into a variable. I now need to search that variable and find
everything between `div class="msgarea"` and the next `/div`
From what I have found elsewhere I think I will need to use a regular
expression but can anyone point me in the right direction as to
exactly how I would go about this?
Cheers

Something like the following:
<?php
if( preg_match( '/div class="msgarea"(.*)\\/div/Uims', $content,
$bits ) )
{
print_r( $bits );
}
?>

Hi,
I just noted that my php (CLI and Apache2 SAPI) doesn't read my php.ini in /etc
I have compiled php with --prefix=/usr, and my /usr/etc is symlinked
to /etc, but it doesn't read the php.ini file..
when I use the CLI with -c /etc it works fine :)

php -i on the command line, or phpinfo() in a SAPI script will tell you
where it expects to find it, as well as whether it did find it.

Is it possible to have PHP code completely separate from the HTML page that
needs to be completely dynamic? (That's how ASP.NET sort of works I think).
If this is possible, HTML CODE, PHP CODE, AND THE CSS CODE can be completely
separate, increasing the clarity of all the source code.
My second question is:
Is it more efficient to always code OOP PHP then just simple functions here
and there?

Take a look at Smarty. :-)

How big is your project?
If you're talking about a personal visit counter, run away OOP.
If you're talking about a really big project (And yes, CMS _is_ a big
project), go ahead and use OOP.
OOP is better to mantain... :-)

We don't need to demarcate, we only need to know that it happened.
Yes, but knowing that something has happened, does not mean that we
know how it happened. :-)
This, my friend, is one of those things we can debate forever without
reaching a definitive answer.
Thus, my assertion that this question is perplexing still stands.
Unless, of course, you wish to challenge it and thus confirm my

like bytes, 00000000 is a fish egg, and 11111111 is a chicken egg,
then it went from fish egg to chicken egg like this:
00000001
00000011
00000111
00001111
00011111
00111111
01111111
11111111
So, at which point do you call it which egg, same with the fish and
the chicken itself. If you call the fish earlier a chicken than you
call the fish egg a chicken egg, then the chicken was first, if you
call the fish egg earlier a chicken egg than you call the fish a
chicken, then the chicken egg was first...

For good grief -- you're going to hurt yourself thinking that way.
The world is not made of one's and zero's but rather thresholds,
chaotic systems, and a bunch of weird stuff we haven't figured out
yet.
We observe phenomena, we develop algorithms and use them until they
don't fit observations anymore and then we develop others to take
their place. And all the while we believe that we have figured
something out, that we know what the answer is -- but the "truth" of
the matter is we're like children putting our tinker toys together to
mimic the things around us. From our perspective, we're pretty good
at it. But, I wonder what the perspective will be one thousand years
from now? Do you think todays answers will serve tomorrow's questions?
You know, I was a lot smarter when I was younger and knew better.

Thank god for that ;) All that computers with ones and zeros is enough :P
But, you CAN compare it with ones and zeros :)

Not tomorrow's questions ;) next year maybe...

Actually in this case there is only one possible way it could have
happened. I'll lay it out simply for you if I must, but it's simple
logical progression.

No, it absolutely has a definitive answer.

The basis of your assertion is incorrect. Methinks you're being
presumptuous by declaring check and mate prematurely.

Can anyone help me with a way to determine of two or more variables have
the same value? For instance,
$a1 = 1000
$a2 = 2000
$a3 = 2000
$a4 = 4000
$a5 = 5000
I want check these five variables and determine whether, as in this
case, two or more of the variables have the same value.
Any suggestions how I can do this?
Thanks in advance.
