Yikes. I'm just reading more about DOM and PHP at the moment on the
PHPBuilder website.
Does anyone have a version of PHP complied with DOM support included for
Windows (I'm developing on a Windows system before moving it over to Linux -
RedHat)?
So loading any old web page and trying to construct a DOM document from it
via PHP isn't going to work? How does IE v5 manage to parse the same web
page correctly (or what seems to be correctly)? I've already read in the DOM
table node elements #text and their values via Javascript in IE.
Still learning lots ;)
Thanks
James

Subject: RE: [PHP-WIN] DOM
I should warn you that XML functions require the document to be
very 'correct'. Most (I guess 98%... I wish browsers weren't so
forgiving, all might've been much easier and better) of HTML
pages on the internet basically aren't HTML (which is a son of
SGML, and an older, heavily cripled brother of XML), and even
strict HTML isn't XML compliant up to XHTML 1.0, which is the
latest version of HTML, fully XML compliant.
If you'll try to load such document into an XML parser, it'll
die with an error message, because XML requires the document
to be well-formed.

It's not PHP vs. DOM. It's XML (DOM) vs. (bad) HTML. PHP just
provides you with an interface to an XML parser.

Any way of doing that would be something of a major change in the way your
application is written. Instead, have you considered caching that update? If
you do it carefully (and maybe work in some sort of diff function so that a
client can only retrieve changes from the previous update) you shouldn't have
problems unless you have many thousands of clients on your network.
Hi,
Installing Phorum, I have some pages running w/o problem, other simply
display an IE error message "The page cannot be displayed". I assume I
changed something (actually I'm struggling with permission settings), so
that some pages cannot be displayed.
Where to look to fix the problems?
Thx for any help,
Marq.
HTML Kit is the best right now - Iam a homesite fan, but the new version is
too much resource eater... so I change to HTML Kit - It is freeware and has
a nice support for file transfers and make a FTP appears like a local
directory, making great for testing... Give it a try... www.htmlkit.com

Hi,
I give my vote to Homesite, too. Very nice project management, and CVS
integration using "Igloo". Great !

The function "Imagecopyresized" is the answer. But what a pity, the provider

Hi,
I've seen that the GD extension provides functions to create and manipulate
images. I didn't find a function to resize an image. Is a resize possible
with PHP or do I have to call an external function?

Get an older version of GD that does. Or grab some of the retrofitted
versions that are floating around out there that support gif, jpg and png.

Title: Blank

A newbie just needs a wee bit of gd guidance. clicking a
GD test file
prompts a "download" dialogue to pop up, or, on a second test
files causes
lines of "font" errors, then the infamous "header already sent"
error, then
lines of character soup.
the test file below, from John
Lim at web.logs.com causes the windows
"donwload file" dialogue to
launch. Gd and zlib both show as "enabled" on
the phpinfo page,
yet this still happens. What could cause this? Anyone has
any
ideas?
<?php
Header( "Content-type:
image/png";
// create image
$image = imagecreate(200,200);
//
create color R=100, G=0, R=0
$maroon =
ImageColorAllocate($image,100,0,0);
// create color R=255, G=255,
R=255
$white = ImageColorAllocate($image,255,255,255);
// create white
background
ImageFilledRectangle($image,0,0,200,200,$white);
// create
frame
ImageRectangle($image,10,10,190,190,$maroon);
// create inner
rectangle
ImageFilledRectangle($image,50,50,150,150,$maroon);
//
render image
ImagePNG($image);
// cleanup
memory
ImageDestroy($image);
?>
