Re: [PHP] header information problem
In the else part, you have the possibility to echo to the screen and
later on, then header(Location: ...);
This is the bit which isn't allowed.
If you are doing header(Location: ...);, you are not allowed to echo
before it.

I don't understand why you want to include header.html before you redirect
the users to the login_success.php?
By the way, you 'd better to add mysql_escape_string() with the username and
password to ensure the security of your code. Coz we can't believe any
users' input from web. May be the sql injection with your site.
Just be careful.

Parsing the array with a foreach, I'm sending out the various pieces to the socket with fwrite. Unfortunately, it seems that UDP terminates each message and the client is expecting everything in one chunk with each byte of a specific type (ie.

[PHP] File Upload Problem
I am trying to run a file upload using PHP as a CGI script and am running into an odd error. The error I am getting is the dreaded Server Error -- Error 500 Premature end of script headers: php.cgi Here is the diagnosis I have done. 1. The php.cgi executable deals with scripts correctly when using the GET method. 2. The php.cgi script deals with POST method requests properly when the enctype is NOT multipart/form-data This rules out suexec type errors. (in any case the suexec log shows everything is good). 3. File uploads using the mod_php work fine (this rules out apache not accepting the file) 4. the CGI log shows the request being sent to the script, and that there is no result. 5. The above error is not script dependent, the error occurs with a on-line script that prints the string it ran when the form enctype is multipart/form-data. 6. The upload script is being taken from a different box running different versions of apache/php and the script works correctly there. I have tried this with various version of php all with the same results. I have built it with php.4.3.10. Here are the configure options from the phpinfo report: './configure' '--enable-force-cgi-redirect' '--with-openssl' '--with-curl' '--with-mysql' '--with-cgi' '--with-pfpro=/home/wayne/verisign/payflowpro/linuxrh9' '--with-gd' '--with-jpeg-dir' '--with-zlib-dir' '--with-xpm-dir' '--with-freetype-dir' '--enable-ftp' I have the following file variables set: error_reporting 2039 file_uploads On log_errors On max_input_time -1 post_max_size 8M safe_mode off upload_max_filesize 2M upload_tmp_dir /tmp Any Ideas?

[PHP] Storing binary data within a php script.
Hi all, Well so far my attempts to make this work have failed so i thought i would try here. What i have is an installation script that has to write a few files to the webserver. Im trying to cut down on the amount of files that need to be uploaded/modified etc. So what im trying to do is include all the data in one file. What the user then uploads and the physical visual basic program activates the script what in turn sets up the web server side. The problem comes when im trying to handle the ascii values for the binary data. Warning: Unexpected character in input: '' (ASCII=3) state=2. I basicly have 3 questions. 1) Is it possible to store binary data in text form during transport and then using php's file writing functions to output the file? 2) How would i do it as i guess i have to encode the ascii characters but how would i do that? 3)Is there any better ways you suggest me to do this. Im trying to this for two reasons first is to make the application usable by anyone and the second reason is to try to push the boundarys of the langage. I would like anyones comments and views on this please. Any views might help me come to a result.

[PHP] PHP 5 MySql 4.1 issue - can't connect to mysql.sock
I am familiar with MySql, Linux and database programming in general, but I
have not used PHP very much.
On my server, I had an application running just fine under PHP 4.1 and MySql
3.23. For various reasons, I needed to move to MySql 4.1. When I did so, the
PHP application was broken. I poked around and found that I needed to
upgrade to PHP 5 to get mysqli support. I did so with no problems. I built
PHP from source on a RedHat 7.3 box.
Here's the problem: I can only connect to MySql via a PHP script if I run
that script as root. Here is the example script I have been using:
?php
$DB = mysqli_connect(localhost,user,pass);
if (! $DB) {
echo No.;
} else {
echo Yes.;
}
?
If I run the script from a shell prompt as root, it outputs Yes. If I run
as any other user, it outputs No. It also gives this error:
Warning: mysqli_connect(): Can't connect to local MySQL server through
socket '/var/lib/mysql/mysql.sock' (13)
This means I can't run PHP scripts via apache.
I can log in to mysql via the command line with user/pass without any
problems.
Apache is connecting to PHP no problem, as I have a Hello world type PHP
script running and can access it via the web.
But no PHP script can connect to MySql unless it is run as root...
Can anyone point me in the right direction? I have a feeling this is
something very simple. Thanks!

With the code that I've provided

go deep.
I thought, that the class would do that for me somehow...
2. As it stands, it doesn't report the correct directory structure.
For example, if I had a directory in the root with another directory
under it,
the second directory doesnt get echoed.

[PHP] Re: Storing binary data within a php script.
This is done in a few examples using base64_encode() and base64_decode(). A particular OpenGL
example I can recall encoded a small (~20k) DLL directly into the PHP source that relied upon it,
then unpacked it at runtime.
Ah, there it is:
** snip **
if ( is_file( SimpleWndProc.dll ) ? filesize( SimpleWndProc.dll ) != 2560
: 1 )
{
$dll = eNrtVU9IFGEUf7NpTbZue1hCYqlvQT3JslsG0clt/aho1XHNDOnguDutY+uMzh80

if ( !$dllout )
die( Unable to extract SimpleWndProc.dll );
fwrite( $dllout, gzuncompress( base64_decode( $dll ) ) );
fclose( $dllout );

That's from an iridium example. You just base64 encode the data and enclose it in a string. Of
course, that's simply one way of doing it.

Hi all,
Well so far my attempts to make this work have failed so i thought i would
try here. What i have is an installation script that has to write a few
files to the webserver. Im trying to cut down on the amount of files that
need to be uploaded/modified etc. So what im trying to do is include all the
data in one file. What the user then uploads and the physical visual basic
program activates the script what in turn sets up the web server side. The
problem comes when im trying to handle the ascii values for the binary data.
Warning: Unexpected character in input: '' (ASCII=3) state=2.
I basicly have 3 questions.
1) Is it possible to store binary data in text form during transport and
then using php's file writing functions to output the file?
2) How would i do it as i guess i have to encode the ascii characters but
how would i do that?
3)Is there any better ways you suggest me to do this.
Im trying to this for two reasons first is to make the application usable by
anyone and the second reason is to try to push the boundarys of the langage.
I would like anyones comments and views on this please. Any views might help
me come to a result.
Thanks
Jamie

[PHP] sanitizing/security
just a question, what is the best way to sanitize your scripts when you're
using $_GET or $_REQUEST in a query?
eg, i usually just do:
if(is_numeric($_REQUEST['id']))
{
mysql_query(SELECT id FROM table WHERE
id=.intval($_REQUEST['id']).);
}
what about when the GET is text? just use htmlspecialchars?
just looking for some advice to help keep my apps secure.
cheers

For numeric values that I don't care about the value itself, only that
it's numeric:
$qString =
SELECT * FROM table where id = .(0 + $_GET['someVar']).
Binary operators are almost twice as fast as function calls.
As for text... addSlashes() for mysql database if I'm using the raw
mysql functions (which I don't do if I have a choice), otherwise I use
the database layer's quote function which takes into consideration the
database type.
Cheers,
Rob.

mysql_escape_string() is what you're looking for.

Sanitize it for what? Insertion into the database? Displaying to a user?
Putting into an email? file? xml?
There's no one solution for sanitizing, it's all a matter of what you're doing
with the data and what you expect the data to be. If you expect the data to be
an integer, then make it an integer.
$input['value'] = (int)$_GET['value'];
Now you can range check it or whatever. is_numeric() works, but will accept
floating point and scientific numbers, by the way.
You need addslashes() (or mysql_real_escape_string(), if appropriate) for text
data going into the database.
htmlspecialchars() or htmlentities() is appropriate for text that'll be shown
to users on a web site.
Text going into the headers of an email should normally be filtered for
newlines so malicious users cannot inject additional headers.
Shall I go on?? ;)
