Hi everyone!

Sorry for the probably stupid question. But I can`t find a way to make a php
script to open an url in a browser!
Like "<script> location = "example.html"; </script>" does.

That has some truth to it. My advice would be to establish a DMZ
(demilitarized zone). One way to do this would require the user of an
extra firewall. I assume that your current setup is a single firewall
between you and the Internet. When you relax your firewall rules to allow
HTTP traffic, your entire local network becomes a DMZ. Some users on the
local network might be running Windows with IIS and not even realize it,
and relaxed firewall rules can expose this weakness.

If you want to only open up additional ports for your server, you would
place an additional firewall between it and the local network, so HTTP
traffic can reach you, but the second firewall prevents it from reaching
the local network.

Apache should not be your concern. Windows is your security weakness, but
your firewall can help protect you. If you only want to be serving HTTP
(I'm assuming no SSL), only allow outside connections to be initiated on
port 80 and nowhere else. With this setup, you are relying on the security
of Apache for the most part (the OS does handle TCP/IP and such).

It is also very important that you do not actually use this computer for
other purposes, such as browsing the Web (e.g., if it's your personal
workstation). If you do, you are likely to get infected with something,
and then the firewall doesn't help you.

This reminds me of another concern, which is your code. Even in the
theoretical case that your environment is 100% secure (a fiction that we
can only strive to achieve), weaknesses in your applications can still
exist.

You cannot provide reasonable security with this approach, in my opinion.

hi all,

Im getting an http 411 error when trying to post data with php's cURL
functions. The spec says

***The message for this error code is "Length Required."
The server refuses to accept the request without a defined Content-
Length.***

Im confused on 2 points:

* Is it the server i am posting *from* causing the error or is it the
  server im posting *to*?

* How to resolve this?

Much thx for any guidance here, this was not happening yesterday doing
the same job.. weird!

do you know if the lenght includes the args? like this

strlen("val=$var&val2=$var2");

or

strlen($var . $var2=;

?

This one. Don't forget to urlencode where necessary

hmmm.. well, this is giving me the same curl_errno(22) http 411

$postF="s=$s&e=$e&a=" . urlencode($a) . "&em=" . urlencode($em) ."&x=" .
$x . "&b=$b&t=" . urlencode($t) . "&p=$p";

$postL=strlen($postF);

curl_setopt($ch, CURLOPT_POSTFIELDS,$postF);
curl_setopt($ch, CURLOPT_HTTPHEADERS, "Content-Length: $postL");

$result=curl_exec($ch);

CURLOPT_HTTPHEADER - An array of HTTP header fields to set.

curl_setopt($ch, CURLOPT_HTTPHEADERS, array('Content-Length' => $postL));

It seems cURL is sending a malformed HTTP request. When I used Curl I
don't let it compose the request. Instead I use this HTTP client class
that lets me use cUrl or fsockopen to establish HTTP connection and it
takes care of sending the HTTP request correctly regardless of the way
the request is sent.

No, PHP errors DO NOT appear in the apache logs[1], they are logged to a
separate file which can be specified in php.ini.

[1] Some PHP induced errors do appear in the apache error log, notably
segfaults.

Hello everyone,

I'm hoping you guys can help me with this error. Here's what I'm getting:

Notice: Undefined variable: children in
L:\localhost\catalog\catalog_0.1.0\includes\classes\tree.class.php on line
58

This error occurs only when the class's method outputs $children as having a
value of zero. Below is the class. I want it to return zero but I don't want
this error. Do I need to change my error settings in my php.ini file? The
error level is currently set to E_ALL and I'm using PHP 5.0.1. If at all
possible, I want to keep this error setting at high because I want
everything to be coded strictly. What did I do wrong in my class and how can
I fix it to where it doesn't output an error when a class's method returns a
value of zero? Here's the class:

    function get_children($parent) {
        $parent_coord = tree::get_item_coord($parent);
        $descendants = $this->get_descendants($parent);
        for ($i = 0; $i < count($descendants); $i++) {
            if ((empty($children)) && (($parent_coord['0']['lft'] + 1) ==
$descendants[$i]['lft'])) {
                $children[] = $descendants[$i]; // found first child
            }
            elseif (($children[count($children)-1]['rgt'] + 1 ==
$descendants[$i]['lft']) && $children[count($children)-1]['rgt'] + 1 !=
$parent_coord['0']['rgt']) {
                $children[] = $descendants[$i]; // find next children
            }
        }
        return $children;
    }

Thanks in advance to anyone that can explain this error to me.

Does anybody know off the top of their head why truetype font text would look greyed out?

This is my code:

<?php

$im = imagecreatefromgif("testimage.gif");
$myfont = "inc/arial.ttf";
$mycolor = imagecolorallocate($im,0,0,0);

imagettftext($im, 8, 0, 580, 118, $mycolor, $myfont, "test string");

imagejpeg($im);
imagedestroy($im);

?>

The text looks greyed out and it's a bit distorted.

Thanks,
Brent
