It has to do with the browser. IE an others don't like *large* data
specially in tables it will hang, just look take a look with the Task
Manager and you'll see IE just going crazy.

Web browsers have to "calculate" the image-output of the page. IE is
specially bad at this as it will generate an in-memory BMP with the full
data. That will mean that a page with some millions of characters will
generate a memory footprint that surpasses all the memory of the
computer and starts to goble disk memory...
Cheers...

P.S.- There is no solution for this problem because web browsers
wheren't designed to handle data that way...

I have a script that grabs some 250,000+ rows, 1 field. Then prints it to
the screen.
The problem is, it takes over 10 minutes just to print. The query itself
takes under 30 seconds. So, is there a faster way to print out 5 million
characters to the web page? This seems to be the slow part. Anyone
experience this and find a solution?
Thanks!

The technical term when a computer is more occupied with
swapping memory pages than actually execute the context
of a memory pages is know as trashing. Most Stupid Windeads
memory handler is also know to start to trash fairly easy
(just try to start up notepad with a huge file and you'll
see what I mean...)

I'm working on a script to control Adobe InDesign 2.0 through COM.
And I'm using som Visual Basic examples to teach myself.
What I'm stuck on is this VB-code:
For Each Story In myStories
Set myParagraphs = Story.Paragraphs
Next Story
How can I write this in PHP?
BTW: I'd really appreciate if someone have some tips or webpages to give me.
Mvh

Something like that...
The way my site is set up all the content is "wrapped" by the index.php
script. So no matter what page your looking at your browser is still pointed
to the same index.php. At times I have pages that have includes that are
five and six pages deep.
The form and validation that does the re-direct could easily be in a page
that's included from another page that's included in index.php and it would
be re-directing you back to index.php with other parameters.
Making it so that there was no output before the header() call wasn't
something I was planning for as I developed it so going back and making it
that way isn't a high priority for me when I have a simple JavaScript
solution.
Browsers with JavaScript turned off isn't a concern because the splash page
of the site requires it and all the people using the site require JavaScript
for other internal systems here.
Maybe at some point I'll rewrite it so the re-direction can be server side
but for now it's serving my purposes.

Hello,
fist of all I want to excuse me for my bad english. But I can't solve my
problem so I have to try it in english. I am working with PHP 4.2.3 and the
Apache-Webserver under Windows 2000. I am using the newest version of the
archive_tar-Class for the building of tar-Archives.
With the following script I get this error message: Invalid checksum : 2826
calculated, 19501 expected0
script archive_test.php
include("pear/archive/tar.php");
$tar_object = new Archive_Tar("tarname.tar", false);
$tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling
$v_list[0]="edit.gif";
$v_list[1]="cms_img/"; // Optional '/' at the
end
$tar_object->create($v_list);
$pics = $tar_object->listContent();
print_r($pics);
The result of the script is an tar-archive with a size of 32 KB. When I look
into this archive, there is just the gif-file edit.gif, and when I trie to
open it directly from the archive (with the picture-viewer acdsee) the
picture is totally warped.
The error appear since Imodified my Apache Configuration so that PHP is
running as an Apache Modul. And since this changeover the tar-Class doesn't
create any correct tar-Archive. When PHP ist running as CGI there is no
problem with the generation of tar_archives - with the same script!
So where I the error? Does the archive_tar-Class not work with php as on
apache-Modul on Windows 2000?
Please help me!
Yours sincerely
Timo
