I have a machine with several websites one of which is quite busy
this time of year. I have another that had its joomla comments on
and open and the spammers found it. They managed to get 700,000
comments into the system before we caught it, but the traffic and strain
on the MySQL server and the webserver (PHP) while it was going on brought
the server to its knees. I've put some iptables rules in to block
the attacks and things are back to normal.
The server (A vmware
VM w/ 2 CPU and 2 GB of RAM) never crashed, but it certainly was on its
knees. The distribution is Gentoo 10.1.
My only other
problem is PHP hanging on MySQL returning an emtpy set.(mysql_num_rows =
0). That 's a whole other issue and off of this topic.

It would be nice to have a list of extensions which were known to not be
thread safe. then one could take more comfort at the prospect of a threaded
environment.

Hi everyone,
Image processing is a part of Php language completely unknown to me
:-(.
So there is my task: I need to process an uploaded image. We allow
uploading of gif, jpeg, and png images. If an image is wider than
600px, it should be proportionally resized to the width of 600px.
Yes, I've just read about ImageCopyResampled().
My questions are:
1. what are the restrictions of ImageCopyResampled()? Can I make a jpg
image from a jpg one, and a png image from a png one? And what about
gif's?
2. I don't need to output the image as the script output, I need to
upload it as a file (replacing the uploaded larger file). Could I make
it with fwrite and then copy it to the server? All of the examples give
header("image/jpeg")...
Thanks!

Hello All,
Is there a smarter way to do includes by setting up a path or something
where I don't have to include /home/domain.com/includes/include_file.php
Apparently my path is as shown above, but I would prefer to just put in
/includes/include_file.php
Thanks!
Jack

As a first action, in whatever file you first include or call, do the
following:
$site_path = realpath(dirname(__FILE__)) . DIRECTORY_SEPARATOR;
define ('SITE_PATH', $site_path);
Next, create a function like:
function include_path($filename)
{
$str = SITE_PATH . 'include' . DIRECTORY_SEPARATOR . $filename;
return $str;
}
Now, when you want to include a file, do
include(include_path('something.php'));
In my projects, I have a variety of directories, like libraries, views,
models, etc. So the function I use has a second parameter:
include(fullpath('model', 'pizza.php'));
include(fullpath('include', 'gesundheit.php'));

Here's how I do it. For every application, I have a config file with all my
common assignments, including common paths, e.g.,
define('EDITPAGE_ROOT_DIR', $_SERVER['DOCUMENT_ROOT'] . '/editPageSR/');
define('EDITPAGE_IMAGES_DIR', EDITPAGE_ROOT_DIR . 'images/');
define('EDITPAGE_DATA_DIR', PAGE_ROOT_DIR . '/editPageFiles/');
So, in your case, I'd have
define('INCLUDE_FILE', $_SERVER['DOCUMENT_ROOT'] . "/includes
/include_file.php");
So all I need is to use INCLUDE_FILE

Any more suggestions?

Hi Ethan,
Are you using suPHP or suExec? I believe the server chokes on 777
permissions in those cases.
Have you checked the permissions in the command line (sorry for the basic
question, but just making sure I know what you've already done?)
Also, can we see some of the code you're using to handle the file
processing?
Thanks,
Adam

Adam -
Thanks.
1] Pardon my ignorance but I do not understand
this - Are you using suPHP or suExec?
2] I changed the permissions to 755 and the
"Permission Denied" message went away.
3] Have you checked the permissions in the command line? Yes
4] Here are some code snippets:
$fptr1 = fopen("chessboard", "r+"); //this works
$fptr2 = fopen('chessboard', 'w'); //this deletes the file, as it should
for($i = 0; $i <8; $i++)
{
for ($j = 0; $j < 8; $j++)
fprinf($fptr2, "%s ", $results[$i][$j]);
fprinf($fptr2, "\n");
} //this never writes, so I am left with an empty file
// I tried the following two code blocks, and the
output files were never created.
$number = 123;
$file = fopen("test.txt","w");
fprintf($file,"%f",$number);
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Bobby Bopper\n";
fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
