Anybody who writes a decent blog system that everybody can use is then
flooded with a zillion "Feature Requests" and, ultimately, you end up
with Bloated Blog.
I do not forsee this problem going away.
Ditto for forums and shopping carts.

I've forgotten the exact cursor syntax, but it's like:
$query = "declare cursor foo as select complicated query here";
$foo = pg_exec($connection, $query);
$query = "select 10 from foo";
$ten_rows = pg_exec($connection, $query);
I have completely forgotten the cursor query to get the number of
rows, but it's in the docs.
You are so totally on your own with that bleeding-edge PDO [bleep].
Sorry.

These two together make no sense at all...
If the $_REQUEST['page'] is NOT set, then why use it? It's NOT THERE.

Here is a more sensible approach:
//use page requested, or default to page 1:
$page = isset($_REQUEST['page']) ? $_REQUEST['page'] : 1;
You can write that as a 6-line if statement if you like:
if (isset($_REQUEST['page']){
$page = $_REQUEST['page'];
}
else{
$page = 1;
}

In that case, you are on ?page=2 in your script, and you didn't do
ANYTHING about $page in the original version.

No.
isset() CHECKS if a variable/index is set. It does not alter anything
at all. It just tests.

TAANSTAAFL
There certainly IS some overhead using PHP downloader script, and a
straight link IS definitely more efficient.
The correct question is "HOW MUCH more efficient"
The correct answer is "You'll only know after you test on YOUR machine"
Note that the bandwidth is probably gonna kill you long before PHP
does, if you write a lean mean PHP application...
If your PHP download script has to include 4,000 class files before it
can do anything useful, well, no, it won't be fast.

Can I respectfully suggest you just take php *OUT* of the equation?
You're talking about something on the CLIENT that needs to indicate
number of bytes SENT by the client out of total number of bytes the
client needs to SEND.
All the information involved is client-side.
Trying to hook PHP, on the server, into this is just plain daft.
Go bug the FireFox guys to give you callback hooks into the upload
process, or submit a patch to them.
Getting PHP involved in this equation makes zero sense -- You'd only
be generating a TON of HTTP traffic for PHP to tell the browser what
the browser already KNOWS.
[/soapbox]
PS
Or you could just train your users to actually look at the progress
meter in those browsers that already have one... :-)

PHP cannot do it. Other languajes, like jsp, is able to report that
information.
I did it with Perl (CGI) and playing with some iframes.
Its a little complex and dirty.

Try with

You might as well delete the first two lines. They don't do anything.
The last line "works" in the sense that no browser currently has any
pre-defined idea of what to *DO* with an "application/download"
because that's not a known MIME-type.
So the browser "punts" and presents a download window, because it has
NO IDEA what else to do.
Some goofball MADE UP application/download and "it worked"
If, however, tomorrow, some MS weenie decides that the Right Thing to
do with application/download is to store it in "My Documents" because
that's where everybody wants all the downloads to go, right?, then it
WILL NOT WORK tomorrow.
It's that simple. IE 8 could decide application/download means "Put
it in My Documents" and you no longer have a download popup.
There is NOTHING to stop the MS engineers from doing that to you.
Nada.
BUUUUUT:
application/octet-stream is DEFINED in the HTTP SPEC to ALWAYS WORK.
Any browser that ever makes it not work is BADLY BROKEN.
They cannot change this tomorrow, without being non-HTTP-compliant,
and breaking backwards compatibility with a zillion Documented
Features.
So, use some goofball header that you make up, like:
header("Content-type: asdfqwerowiru/werouitohvosdfho");
and it will "work"
Or, realy on a DOCUMENTED FEATURE and use:
header("Content-type: application/octet-stream");
Your choice, really, though obviously I have a strong opinion on which
one is the Right Way to do it.

It is possible that all "modern" browsers have given in to whichever
johnny-come-lately 'standard' made up the Content-disposition header.
I know for sure it did not work in some browsers back in the day.
I'm only saying that
Content-type: application/octet-stream
has worked from the very beginning of time, and is a Documented
Feature, and is incredibly unlikely to ever not work.
If you don't care about ancient, niche, or otherwise "odd" browsers,
fine.
If you want something that works for EVERY browser for the beginning
of time, and will almost-for-sure never not wor, unless the spec
changes in a non-backwards-compatible way, breaking a zillion web
applications...
You choose your headers, and you take your chances.

But they downloaded it.
They HAVE the data, it's just got a filename they don't know what to
do with.
If they just change the extension to whatever it should be, it would
be fine.

Well, then, you've just eliminated a correct technical solution for
non-technical reasons...
I cannot do much about that...
Actually, if you REALLY want to be browser-compliant back to the stone
age, and througout the dreaded 3.x and 4.x series, you would need to
get the URL to be just:
http://example.com/script_that_looks_like_dirname/filename.ext
That odd-looking dirname is a PHP script.
URL juggling with mod_rewrite ForceType and $_SERVER['PATH_INFO'] is
the tech.
The browser then CANNOT screw up beause it "looks" like a static URL.

My code basically looks like this:
header("Content-type: application/octet-stream");
Though, admittedly, the 3 lines in .htaccess should "count"
And, if you want input parameters in the URL instead of GET (which
will mess up FDF files) then there's another 20 lines to parse
$_SERVER['PATH_INFO'] into an array, just like $_GET and $_POST, only
not.
But then, that code is in an include file and gets re-used for a lot
of different rich media (images, PDF, Ming flash movies, etc) so it's
got a decent re-use factor.
Maybe I'm just re-using code from 5 years ago that could be replaced
by the browser-detecting (assuming the user-agent doesn't lie) and
using some new-fangled headers...
Or I could just keep using the code that cannot break. Yeah, I like
that.

The original RFC for it is dated June 1995, so it's not too recent.
There are plenty of useful aspects of HTTP not defined in RFC 2616.
Content-type: application/octet-stream
There's no reason you can't use both.

You do not need to use a separate program to upload files with forms.
You can use PHP with socket connections.
Take a look at this pure PHP HTTP client class that lets you post files
for upload. You can just point it to a local file or some dynamically
generated data. It lets you choose the the file name in case you do not
want to use the local file name. Take a look at the test_http_post.php
example:

Hi,
I have several websites that are using a common set of pages (to reduce
maintenance, development and upgrading) and use configuration files to give
the customer the feeling that it is their own unique site. The customers are
all universities and use the sites to manage digitisation and copyright
permission processes. These sites are all hosted om my company server.
I would like them to be able to see whether a PDF file hosted by their
universities is available or not.
Using file_exists($url) won't work because the actual PDFs should be sitting
behind the universities' firewalls.
I think that something working on the client-side, such as JavaScript might
work, because it would be able to look from the client's machine to the PDF,
both of which should be behind the firewall to the PDF. However, I haven't
been able to find any js that looks like it will do that for me.
Does anyone have any constructive suggestions?
