That's probably the reason why they are named "SuperGlobals". :-)
But to be more descriptive, these are simply globals that are predefined by php
-- see:
http://php.net/manual/en/language.variables.superglobals.php
I believe, (please show me otherwise) there are no "globals" in PHP other than
SuperGlobals.

you may find it weird, actually very weird, but is the following possible>
load up a post or page into the admin panel and place something like
this in to the editor;
<?php
//assume exec-PHP already active
$current_page_url_here = get_current_url();
echo "<a href='{$current_page_url_here}?var1=val1'>click me</a>";
if ( $_GET['var1']=='val1' )
{
//change the current post's html title to <title>val1</title>
without using javascript/jquery
}
?>
so when the visitor, clicks on the "click me", same page reloads but
this time, the title reads val1, and that's what search engines see
too.
and if it is also possible to change, the_title() to be equal to val1,
that's even better.
But, is such a thing technically possible? Or is it too late at that
time to make those changes?
Could ob_start in any shape or form be deployed here to achieve this goal?

Based on the terms you're using it sounds like this is a Wordpress
question. You'd have a lot better chances of getting an answer if you
query a group of WP gurus/geeks.

This is not a WYSIWYG editor question; WYSIWYG editors are things
like KompoZer, Dreamweaver, FrontPage, and even web-based things like
TinyMCE, et al.
That aside, try this very basic example (and expounded) and see if
it's what you're trying to achieve:
<?php
echo '<title>';
if (isset($_GET['title'])) {
echo $_GET['title'];
} else {
echo 'The title has not been set!';
}
echo '</title>'.PHP_EOL;
echo '<a
href="http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].'?title=Enter+your+title+here">Change
Title</a>'.PHP_EOL;
?>

Did you understand what I meant by "very basic example?" You'd
need to modify your <title>.*</title> tag in the head, as well,
obviously. That's all quite logical, and well beyond the scope of the
initial question.

Yeah, but n the context of wordpress, that does not fly.
If I do a die; in the middle of wp's tinymce editor, and check back
the page, the title is already out there.
first 5 lines would be something like
<!DOCTYPE html>
<html dir="ltr" lang="en-US">
<head>
<meta charset="UTF-8" />
<title>the wordpress page title we were trying toi change is already
here...</title>
<link rel="profile" href="http://gmpg.org/xfn/11"; />
But this question is a wp question. I accidentally dropped it in the PHP group.

Any reason you can't just use JS to alter the title tag on the page loading?

Search engines would still be indexing the original page's title. I
need each unique URL to have its own unique, robot friendly title.
Again, this question is strictly within WP context.

Hi,
I've been wondering where the letter was chosen from too, so I took
svn and got all the way back to revision 214 where the options was
first added. Note that this commit is June 7, 1996, and we're talking
about php2 (php/fi) here. I tried to look at mailing list archives,
but it seems that rasmus was pretty much developing PHP on it's own in
those days.
It seems that it has been added when cookie support was added, and for
the cookie to set a date they wanted a nicely printed day. It seems to
be just a choice from rasmus back in those days.
My best guess would be that the 'l' is chosen because it is the last
letter of 'full' in 'full name of day', though I don't understand why
'f' or 'F' wasn't chosen.
Well, try remembering the 'l' in 'full' if you need it the next time..;)

How about "long" dayname?
I find it interesting that the character for "Day of the month without
leading zeros" is j, which makes sense to me as a half-Francophone who
sometimes calls days "jours". Not that it helps me remember it, I
have to refer to that page pretty much every time I use date().

You are some sleuth! Let me know first if you ever have any dirt on me, Matijn!
Thank you for the mnemonic "full". I'll know next week if it sticks or
not. Though, I already foresee myself trying to use "f"!

I also refer to that page enough to have it bookmarked on my homepage!

Hi Simon,
Moving the set_error_handler to index.php gives the developer the ability
to remove it before pushing the site to a production environment. I agree
that in most cases you don't want the live site to fail completely when it
trips over an unset variable but I prefer to have it on by default to
encourage good habits.
Moving the autoloader as well is a good idea but I'd need a copy of the
function wherever I bootstrap Swiftlet (e.g. tests). It doesn't seem worth
the trouble to avoid two require statements.
Plugins are quite simple and can indeed extend anything, including other
plugins.

Dear all
i'm trying to handle a max timeout into a file_get_contents request,
this is my code:
******* client.php ******* placed on http://test.foo.com/client.php
<?php
ini_set('default_socket_timeout',10);
$ctx = stream_context_create(array('http' => array('timeout' => 10)));
$data = file_get_contents("http://www.foo.com/server.php",0,$ctx);
if(!data){
die("error during page request");
}else{
echo "OK";
echo $data;
}
?>
******* server.php ******* placed on www.foo.com at
http://www.foo.com/server.php
<?php
sleep(15);
echo "OK";
?>
i've noticed that in a standard scenario if i call
http://test.foo.com/client.php all works properly and the timeout is
handled correctly.
But, if i'm experiencing dns lookup problems, the timeout setting is
ignored by file_get_contents, or more probably the socket isn't yet
estabilished so the counter for timeout doesn't start.
I've been able to reproduce this problem on a linux server dropping
incoming packets of DNS with this command: (be careful, it will
disable you ability to resolve all dns address!):
* iptables -A INPUT -p udp --sport 53 -j DROP
* iptables -A INPUT -p tcp --sport 53 -j DROP
So, the question is:
is possible to have a timeout check that includes also dns resolution time?
Thanks to all in advance
