I'm not sure what you mean.
10 different programmers would do this 10 different ways.
Personally I'd create a forum-data manipulation API, and then create a
frontend to access this.
I suggest you abstract the data access routines into an API of its own, so
that when you come to your senses, you can change it to a proper db.

Hi all,
I'm having some pain with this process. I'll try to explain it well, my
english is little bad... :-)
I've got two main loops, handled by timeouts. One loop calls to an
object method every half second to do a computation. It reads from
external device, creates helper arrays for calculations, and then
creates/updates another array where the final calculations are stored.
In the other loop, fired by events or some circunstances, I loop thru
the calculations array and get the new state for some values. This is
not done on the same object.
I'm having some memory leak trouble while doing that from within objects
using global variables to store the associative arraya, so it seems to
me that some references are keep by php to these data I do generate and
destroy or update on each computation loop, and that memory it is not
freed anytime until program execution ends.
If I do the same computation, but I don't do the data lookups to the
associative arrays, the memory is normaly fred as expected -I noticed
the same trouble with this that depends on how the arrays are handled or
accesed before deleting them, when trying to test for that problem-. But
if I do the array lookups (i mean with this to do a loop to the array to
get all item updates ...) to data is being processed / updated from
other objects, the trouble I explained begin...
It is somewhat complex to give an example to reproduce the whole
thing... Notice I use php4.4.1, and sadly, it is a long running script
as it handles some phpgtk interface.
I noticed the same results when converting these global variables to
local object properties, sadly. It is possible on PHP4 to call on
runtime to the garbage collector? possibly via a php extension / C code?
Does the php garbage collector keep track of uncollectable objects /
zvals as python gc does?
It is some way to freed some memory I know it should be really
unreferenced? Some thing like a manual force to the garbage collection
of a zval -associative array at php level-?
Perhaps should I use a different mechanism for storing the associative
arrays so I could not suffer this issue?
If my trouble is not very clear, please don't hesitate to ask me.
Thanks in advance.
Regards,
Gonzalo.

Hi:
I know how to create a watermark by simply imposing one image on
another via imagecopy() or imagecopymerge().
However, is there a way to place a watermark on a image such that the
watermark is actually anti-aliased against the background of the base
image?
For example, please review:
http://xn--ovg.com/watermark2
The centered watermark is clearly problematic because it was
originally generated with anti-aliasing ON over a white background --
and thus white pixels are shown mixed throughout.
I could turn off the original anti-aliasing in generating the
original watermark, but then I get a jagged watermark that looks just
about as bad.
So, what I am asking is there a way to place text on an existing
image such that the anti-aliasing adjust (i.e., smart) to the
background of the image?
One of the possible solutions I was thinking was to create an image
and then draw text on top of it, via something like this:
<?php
Header ("Content-type: image/gif");
$im = imagecreate (150, 150);
$background = ImageColorAllocate ($im, 238, 238, 238);
$text_color = ImageColorAllocate ($im, 00, 51, 102);
ImageTTFText ($im, 20, 45, 30, 130, $text_color,
"arial.ttf","copyright 2006");
ImageGif ($im);
ImageDestroy ($im);
?>
But, it's not an image that's imported and the background in only one
color. So, is there a way to load an image and then draw smart
anti-aliased text on top of it?
Many thanks to all who reply.

Create the image you are going to watermark with as a PNG, png
doesn't suffer the issues of the antialiasing issues like GIF.
You just want to make sure you use the function:
imagealphablending();
On the original image before you apply the watermark in your merge.
$image = imagecreatefromjpeg($source_file);
imagealphablending($image, true)
$watermark = imagecreatefrompng($watermark_file);
and then just do your imagecopymerge() normally

Curt:
First, thanks for helping.
Second, I wasn't using a GIF -- my copyright was a png and my image was a jpg.
Third, the following is my code, I think I'm following what you said
-- but something is wrong -- the problem remains as shown here:
http://xn--ovg.com/watermark3
--- code follows ---
<?php
$original=imagecreatefromjpeg("mydog.jpg");
imagealphablending($original, true);
$watermark=imagecreatefrompng("copyright.png");
$osx=imagesx($original);
$osy=imagesy($original);
$wsx=imagesx($watermark);
$wsy=imagesy($watermark);
imagecopymerge($original, $watermark, ($osx-$wsx)/2, ($osy-$wsy)/2,
0, 0, $wsx, $wsy,100);
imagepng($original, "trans.png");
?>

Just add a different letter to the end of the string. So long as it isn't
"e" it should be ok yeah?

You'll need to initiate a new request. Browsers don't execute PHP code.

If you're using PHP in the usual way as a server-side script, it
doesn't run in the same time-frame as user interaction such as
clicks. First PHP generates the page and downloads it to the client
(browser); then the human interacts with the page.
Therefore in order to trigger a PHP function from a human event, you
must request a page or submit a form to the server.
However, it sounds like what you're really after is an immediate
response to a user action, in which case you should be using a
client-side scripting language such as JavaScript.
If you really do want to execute a PHP function on the server after a
client-side interaction, you can:
1) request a page with parameters, such as:
<a href="http://example.com/smart.php?thing=thang";>click here</a>
2) submit a form with fields that contain the parameter values:
<form action="smart.php" ...>
<input name="thing" value="thang" ... />
3) use "Ajax" technology (XMLHttpRequest) to bring new data into your
web page without making a complete reload request.

Hi gang:
Given an image, what's the average color?
Here's an example:
http://www.degraeve.com/color-palette/
I would think that one could load an image (or a portion of it) and
then go through it pixel by pixel to determine what the average RBG
content would be. Is there a routine for that?
Thanks.

Hello,
I would like to use PHP as a content filter for proxy. Has anyone tried
this before?
Is there a way to interface PHP with Apache2's proxy mechanism? I can
fetch the page myself or let apache do it, but I would like to change
the final data before it passes the client.
Is it possible with current PHP?
Juraj.

Next time direct your question to the PEAR General List
([EMAIL PROTECTED]) to get a much more useful answer.
This is due to the default mode of Spreadsheet_Excel_Writer creating an
Excel 7 (or maybe 6) compatible spreadsheet which has these string
limitations. If you change the version of spreadsheet it is creating you
will not have these problems.
I don't know the exact commands or versions to set it to but check the
documentation or search the archives of pear-general. I know for sure it
is in the pear-general archives as this question has been asked and
answered many times.

Hi,
Is PHP gonna support multi-threading (not multi-processing) capabilities
in the future?
Even just for the CLI (and CGI) mode.. It would be very helpful to use
PHP as server scripting language on linux (rather than perl). ;-)
Where can I check the road map of PHP development?

Sorry, but no... This is multi-processing, not multi-threading. And it's
supported on CLI mode already and not on windows.

Well, if you're willing to ignore all the unicode stuff, you can use
strlen() since 1 byte = 1 character. Check that manpage to see if there's
a unicode safe version.
also i need to know how to find out how fast a page renders
example;
page rendered in 1.114 seconds
microtime().
Call it at the beginning of your script, then at the end, and substract
the two values to see how long it took.

strlen will count bytes but not necessarily characters (if unicode
is used)

Hello,
What is the future of the xml-rpc client and server functions in php
5.x? I see the old xml-rpc extension is still marked as expirimental
and the newer xml-rpci extention in pecl has not been worked on in 12
months and doesn't have server functionality. I am in the process of
porting a large web app to php and I want to use the most updated and
maintained xml-rpc implimentation.
