Since I know nothing of how this works, does this actually create a physical

This is a moot point now as I have done what I need without using gd, but it
would be nice to find out what the problem is.
Thanks.
Anyone know of a way I can test this further. A small script perhaps.
<?php
$image = imagecreatetruecolor(50, 50);
imagefilledrectangle($image, 0, 0, 50, 50, 0xffffff);
imagejpeg($image);
?>
It creates it in memory and it's a 50 x 50 white square.
Change the 0xffffff to 0xFF6600 and it should be a red square.

Hi,
How can I find out the upload date of the file to the server using PHP

Might do it for you. Maybe check access time, although if you access the
file at after its uploaded, the access time is changed. Maybe mtime?

Ok. Thanks.
You only have to change the function *length() *by the function *strlen()*

Sorry, dont know where my brain was that day, what I
meant was he needs like 5 template pages, with 5
"dynamic" spots on them (meaning that php will
generate the content for these 5 spots and they are
the parts that will be constantly changing depending
on the page), and identical pages will be used to
serve people with other languages except with a color
difference (meaning different colored graphics, not
just css)
My fault for not explaining it better, sorry.
Thanks,
Ryan

I'm not criticizing. You may do whatever is your custom, but the attribute
"bgcolor" for the body tag is better served in a css format. The whole point of
css is to remove attributes from markup.
I realize that people have their own ways that work better for them -- nothing
wrong with that. And, if you need (for whatever reason) to change the
background color of a body tag programmatically, then your way works for you.
But for me, I would move it to embedded css -- that way I know where all
attributes are (embedded or in a css file) and don't have to go through my
markup trying to find why some presentational element isn't working correctly.

The need is in organization.
We don't write code in machine language, which would be faster. We write it in
whatever language (organization) is our custom, which is expensive. Everything
has a price. But, I would guess that the hit to the HD for loading a few extra,
but shorter, files would be very minimal as compared to loading one larger file
per page.
After all, we use includes in php the same way and I don't hear people saying
"Don't use includes because of the extra hits to the HD" -- do we? We do it for
organization.

That's the housekeeping I spoke of. We all have different techniques and
manners of organization. Mine works for me. If I forget an include, then that
page would simply be missing that feature, but the page would still work and
validate.

The tags in my "includes" always balance because I design them that way --
again, that's my organizational manner. The only includes that don't balance
are my header and footer includes -- but the header ends, and the footer
starts, with a body tag.
In short, my organization technique works and I don't have the problems you
describe.

Then within each of the "dynamic" spots run your php.
<?php include('spot1.php');?>

The interpreter actually DOES care, but you have to be wise enough to
enable E_NOTICE messages for the interpreter to tell you that it does
care.
You may want to get in the habit of using .htaccess to do that, as you
will be more comfy with PHP helping you catch any typos in failing to
initialize vars.
:-)
I do that here....our development and staging servers have all errors
turned on whereas on our production server, pretty much everything is
turned off. In a /perfect/ world, you would never see an error in my
code, as I _try_ to write clean code, and trap all the errors before
they get to the screen (no, not by the use of '@'). Since this is not a
perfect world, and I don't always write clean code, it's nice to see
those notices/errors pop up on the screen before the code gets live. ;)

Nicolas, Jochem, Tul,
I have been going mental, reading the online manual and trying different
things. I can not get this loop to work.
Please understand that I have endeavored to read up on list(), each(),
foreach(), while(). key(), and everything else I can. I've even looked
at online tutorials and I have to PHP books here. I'm asking on list not
because I come here before searching for existing help, it's because I
don't understand the help that I've found.
In fact, I've tried lifting code directly from a book I recently bought
on PHP, called "All In One: PHP, MySQL and Apache".
foreach($elements as $e){
while(list($key, $value) = each($e)){
echo "key = " . $key . "<br />";
echo "value = " . $value . "<br />";
}
}
But it still doesn't work. It says:
Warning: Variable passed to each() is not an array or object in
/home/dave/web_sites/thinkingworks.com/web/Article.class on line 60
I tested my code upstream to make sure my array does have the correct
values in it:
echo "This is the id for elements : " . $elements['id'] . "<br />";
echo "This is the type for elements : " . $elements['type'] . "<br />";
echo "This is the resource for elements : " . $elements['resource'] .
"<br />";
echo "This is the parent for elements : " . $elements['parent'] . "<br />";
This outputs:
This is the id for elements : 2
This is the type for elements : Text
This is the resource for elements : 1
This is the parent for elements : 1
Which is all I really want to do, but since it's a multidimensional
array, I can't get at the next set of values that follows the first.
Part of what I don't get, and part of what led me to the first question,
is that I don't get why a while() loop is so easy with
mysql_fetch_array, and yet to act on a multidemensional array in any
other way seems to be so complicated, with so many ways to skin a cat.
I tried what was suggested here on this list, by Tul, too:
foreach($elements as $e){
echo "e[type] = " . $e['type'] . "<br />";
echo "e[resource] = " . $e['resource'] . "<br />";
}
Which produced really weird results:
e[type] = 2
e[resource] = 2
e[type] = 2
e[resource] = 2
e[type] = T
e[resource] = T
e[type] = T
e[resource] = T
e[type] = 1
e[resource] = 1
e[type] = 1
e[resource] = 1
e[type] = 1
e[resource] = 1
e[type] = 1
e[resource] = 1
I could cycle through the other variants I've tried, but the bottom line
remains the same - it ain't working, the results don't match what I'm
seeing in the references, and I don't understand what's going on.
It would be really great if someone could lead me out of the darkness.
Thank you for your advice.

don't fix list()+each() with foreach() ...
// things to do when your stuck:
echo '<pre>';
var_dump($elements);
print_r($elements);
foreach($elements as $e) {
var_dump($e);
print_r($e);
}
echo '</pre>';
// example 1
foreach($elements as $e) {
echo "value= ",$e,"<br />";
}
// example 2
foreach($elements as $key => $value) {
echo "value= ",$value,"<br />";
echo "key= ",$key,"<br />";
}
// example 3
reset($elements);
while(list(, $value) = each($elements)) {
echo "value = " . $value . "<br />";
}
// example 4
reset($elements);
while(list($key, $value) = each($elements)) {
echo "key = " . $key . "<br />";
echo "value = " . $value . "<br />";

Hi all,
I have simple code below :
It run ok in one of my test server (Red Hat Enterprise) , PHP 4.3.2.
However in the one of production server which have same OS and PHP
version , the code did not display "done parsing xml" in log file. It
just display "starting parsing xml" only.
I have check all setting in php.ini , however cannot found any
different between 2 server.
Anybody have any ideas what happening here ? Thanks
<?php
$xmlfile = '/test/test.xml';
$_logger->logdebug("starting parsing xml");
$doc = xmldoc($xmlfile);
$_logger->logdebug("done parsing xml");
?>

What does xmldoc() do? Perhaps it reaches some critical error within
that segment and causes the script to never complete?

Maybe when parsing the xml, the function throws an exception. That
happened to me with PHP 5 xml builtin support, which uses libxml to
process xml's, it can be that your document is malformed, you could try
with a php debugger (like zend debugger).
