Torsten,
Thanks. I think I'm going to start with htmlspecialchars().
htmlentities() might be over kill?

It's super easy, actually. There's been a wee bit of code floating around
the mailing list for 5 or so years for this:
function PostToHost($host, $path, $data_to_send) {
$fp = fsockopen($host,80);
fputs($fp, "POST $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
fputs($fp, "Content-length: ".strlen($data_to_send)."\n");
fputs($fp, "Connection: close\n\n");
fputs($fp, $data_to_send);
while(!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
Just modify to suit and you're good to go. Note: you need to URL-encode the
data you send into a string before passing it to the above function.
Hope this helps,
Torben

Use session var if you are already using sessions, else use cookie

Sessions are one way to deal with it, and would make the thing much
easier than setting your own cookies and hoping the user has cookies'
enabled (never a safe bet)--at least, assuming your PHP is configured
correctly. However, unless you wanted to send all the form data in the
cookie, you then need a way to store the data on the server side,
probably in the session manager. Not hard, but not an obvious win
over just posting the data where you wish.
In this situation, I would probably combine the two techniques and just
store the $return_url in a session var and then use the postToHost()
function to do the final post back to that page.

Not sure what you mean here. The browser is irrelevant with the posting
code. Using sessions means more interaction with the browser, not less.
The less you need to depend on the browser, the less you'll have to debug.
Granted, with the proper setup this is not so much of an issue with
sessions, but just posting the data saves a bit of server-side work.

What if the SQL they inject doesn't have any quotes? Depending on how
you create your SQL statement, magic_quotes_gpc may have no effect.

No, it'll simple escape quotes in strings that are passed into those
variables. If the injected SQL doesn't have any quotes and you're not
quoting it in your SQL statement, then there's no protection.

This is fine if you control every server you develop on, but most people
can't do that.
Write your own escaping function that detects the magic_quotes_gpc
setting and act accordingly. Pass flags for whether your escaping the
data for insertion into a database or for displaying in HTML. Turn off
magic_quotes_runtime within your script, too.

With regards to magic_quotes_gpc, you can't just "treat it as if it were
off" otherwise you may end up escaping data twice if it's not really off
on a server that runs your code. Detect it's value with
get_magic_quotes_gpc() and act accordingly.

I have been working on this all day, and am not getting this to work. I
am creating an application where a user would authenticate against
Active Directory. Yesterday I was able to get PHP to connect to the AD
server and display entries using this script.
<?
// PHP script to connect to the Active Directory Server a return a
result
// used for testing Active Directory connections.
$dn = "OU=Staff,OU=LCDC,OU=Anoka-Hennepin,DC=ah,DC=isd11";
$attributes = array("displayName", "department");
$filter = "(cn=*)";
$ad = ldap_connect("ldap://myadserver")
or die("Couldn't connect to AD!");
ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3);
$bd = ldap_bind($ad, "CN=Tuller\,
Mike,OU=Staff,OU=LCDC,OU=Anoka-Hennepin,DC=ah,DC=isd11","password")
or die("Couldn't bind to AD!");
$result = ldap_search($ad, $dn, $filter, $attributes);
$entries = ldap_get_entries($ad, $result);
for ($i=0; $i<$entries["count"]; $i++)
{
echo $entries[$i]["displayname"]
[0].", ".$entries[$i]["department"][0]."<br />";
}
ldap_unbind($ad);
?>
Everything lists correctly. I looked on the web, and in the mailing
lists, and between the two have come up with this script to
authenticate. I have a web page with forms to enter the username and
password.
<?
$dn = 'OU=Staff,OU=LCDC,OU=Anoka-Hennepin,DC=ah,DC=isd11';
function ldap_authenticate()
{
$username = $_POST['username'];
$password = $_POST['password'];
if ($username != "" && $password != "")
{
if (! ($ad = ldap_connect("172.22.1.20")))
{
die("Could not connect to LDAP server!");

Hi,
Can someone tell me why

My guess is you didn't come to the page with that code on it from
another page (ie a link of some kind), and if you did, the referer
wasn't set by your browser.

If you didn't get to the page by clicking on a link, then you won't
have a referer. Also, you should use quotes around array keys:
$_SERVER['HTTP_REFERER']

It could be the server. I never fully investigated this, but IIS 5/5.1
doesn't report an HTTP REFERER....
The last time I checked this out, was on w2k/iis5 and winxp/iis5.1 (pre sp1)
maybe over a year ago.
Could someone verify/deny this, so I know that Im not crazy ;)....

Hello,

The errstr said "25: Inappropriate ioctl for device".
I'm using PHP 4.3.0. Its phpinfo indicates that OpenSSL is
enabled.
However, I also tested the script on a server with php 4.3.2
and it works perfect. Both PHPs are OpenSSL enabled but
why behaved differently?
Thanks in advance!

There's no practical limit on the size of sessions, but they are not the
place for template files. Neither are databases. Use the file system for
files ;) and include() or fopen() the templates, etc. Use Smarty or a
similar system if you want caching.

Either method will work. You just have to realize that sometimes the IP
address is not sent. There is no reliable way to get the clients IP
address, so do not depend on it.

A variety of ways. What I meant is that it's not sent in the browser's
headers that it sends to the site, which is where getenv() and
$_SERVER[] would snatch it from.
Do not rely on IP addresses. Trust me.

The httpd server might know the remote IP address, but that doesn't
mean that it has to tell PHP about it. The SAPI module may or may not
set the value, for instance.
Even if you could rely on the IP address, in many cases it will not
do quite what you want. For instance, if you try to organize users
by IP address, you'll find that many users can appear to have the same
IP address, such as when they're behind a firewall or using a workstation
on an internal LAN--they may all appear to be coming from the same address.
Hope this helps clear it up,

If you don't see the IP address somewhere in the $_SERVER variable, then NO.

Correct me if I'm wrong, but shouldn't $_SERVER['REMOTE_ADDR'] always be set
if you're using Apache? I've never experienced a case where it was not
available. I'm no C guru, but from what I can tell by looking into the
source for PHP 4.3.7 and Apache 1.3.28 it looks like Apache makes this
variable available to PHP based on the information it stores internally
about the currently-open connection to the client (see Apache's
"src/main/util_script.c", line 292). Have you experienced a case with
Apache & PHP where this variable was not available? Just curious...

Look some form of IP *will* be set and *will* be available in $_SERVER. What
you was using in your original post has been deprecated and thus may have
mislead you into thinking that no IP was set. Use the info in $_SERVER and if
you come across a situation where the IP is not set then file a bug.

It should be there, but mostly because the CGI 1.1 spec requires that it
be provided to the script. There is no physical requirement for it to be
there.
Reasons for it not being present could include:
o Incomplete SAPI code;
o A bug in the httpd or SAPI module,
o etc...
Even if it is there, it's entirely possible that it's just the IP address
of a proxy--or even some other IP address entirely; it's not hard to spoof.
Of course, all of this only applies when running as a CGI or module for
handling web requests. No $_SERVER['REMOTE_ADDR'] will be set when running
on the command line.

I'm trying to send some binary data to a UDP server using PHP. The examples
I've been able to find show sending binary data over TCP, or they show
sending text over UDP.
I'm constructing the messages using the below:
$text_msg = "Hello, World\r\n";
$binary_msg = chr(0x01).chr(0x02).chr(0x00).chr(0xAD);
$binary_msg_size = 4;
I've tried a couple methods of sending the data:
$fp = fsockopen("udp://" . $host,$port,....);
fwrite($fp,$binary_msg,$binary_msg_size);
and
$sock = socket_create(AF_INET,SOCK_DGRAM,SOL_UDP);
socket_sendto($sock,$binary_msg,$binary_msg_size,0,$host,$port);
In either case, a UDP packet is sent, but with a zero data size. If I
instead send the $text_msg, it works as expected. For some reason sending
the binary data doesn't work.
Does anyone have insight into how to send binary data over UDP using PHP?

I use the following without problem:
$fp = fsockopen("udp://www.server.com", 24250, &$errno, &$errstr, .2);

$trigger =

Thanks for the feedback. As it turns out, the reason I was getting zero
data bytes in my UDP packet was that I had declared the packet variable
outside the function in which I was using it.
$packet = chr(0x01).chr(0x1d).... etc
function doSomething($x)
{
// using $packet in here gives you an empty variable.
}
So I guess it was a very basic PHP language thing I was running into. Guess
I've done too much Perl and assumed the variables were accessible in the
function. :-)

Strange as it works for me (http://fred.kwikin.com/user.php) with this
code exactly:
<?php
function fun($arg) {
$arg++;
}
$var = 0;
echo "Before:$var<br>";
call_user_func_array("fun", array(&$var));
echo "After:$var<br>";
?>
What version of PHP are you using?

Did you even try it!

In the below code the variable $thecomments might have some quotations in
it. Like:
$thecomments = how you "like me now"
I'm trying to display the value of that variable in an input box using the
value=" " as shown below; however, the double quotations are screwing me up.
Can someone please make some suggestions on how I can fix this. I've tries
several combinations.addslashes, value= (no quotations, etc). Thanks.
$thecomments = addslashes($row_allitems[6]);
// echo $thecomments;
// this is the section to list the instructions
comments
echo
"<tr>
<td colspan=\"2\" > <div
align=\"right\">Instructions/comments:</div></td>
<td colspan=\"3\"> <div align=\"left\">
<input
name=\"instructionslist[$row_allitems[0]]\" type=\"text\" size=\"50\"
maxlength=\"255\" value=$thecomments></td>

You want htmlentities(), not addslashes().

Seriously, how many times can this question be asked in a week?
You just need to run htmlentities() or htmlspecialchars() on the data
before you place it in the <input> element.

You could always use the built in php function pathinfo()

Hello List,
I'm trying to get the following code to work :
<?
$dn = array("countryName" => "US",
"stateOrProvinceName" => "state",
"localityName" => "town",
"organizationName" => "foo",
"organizationalUnitName" => "foo",
"commonName" => "www.domain.com",
"emailAddress" => "userdomain.com");
$privkey = openssl_pkey_new(array("config" => "/usr/share/ssl/openssl.cnf"));
// Generate a certificate signing request
$csr = openssl_csr_new($dn, $privkey);
// You will usually want to create a self-signed certificate at this
// point until your CA fulfills your request.
// This creates a self-signed cert that is valid for 365 days
$sscert = openssl_csr_sign($csr, null, $privkey, 365);
// Show any errors that occurred here
while (($e = openssl_error_string()) !== false) {
echo $e . "<br>\n";
}
openssl_csr_export($csr, $csrout);
openssl_pkey_export($privkey, $pkeyout, "");
openssl_x509_export($sscert, $crtout);
$match = openssl_x509_check_private_key($crtout, $pkeyout);
if ($match) {
echo "<p>Yes, these match</p>";
}
else {
echo "<pre>Error: crt and key do not match</pre>";
}
exit();
?>
The code is mainly from the php manual pages and notes.
It appears to correctly generate a key, csr and crt. However when I try to verify
them with:
openssl_x509_check_private_key()
I get a mismatch. Any ideas?
There are some errors generated on the csr creation but when I echo the text of the .crt and .key
they appear to be valid so I'm not too sure what is going on?
Is anyone aware of where I can find some code similiar to this that works (create csr and key on
demand). Thanks in advance!

=======================================
Please feel free to add more points and send
to the list.
=======================================
1. If you have any queries/problems about PHP
try http://www.php.net/manual/en first. You
can download a copy and use it offline also.
Please also try
http://www.php.net/manual/faq.php
for answers to frequently answered questions
about PHP (added by Christophe Chisogne).
2. Try http://www.google.com next. Searching
for "php YOUR QUERY" may fetch you relevant
information within the first 10 results.
3. There is a searchable archive of the
mailing list discussion at
http://phparch.com/mailinglists. Many of the
common topics are discussed repeatedly, and
you may get answer to your query from the
earlier discussions.
For example: One of the repeatedly discussed
question in the list is "Best PHP editor".
Everyone has his/her favourite editor.
You can get all the opinions by going through
the list archives. If you want a chosen list
try this link :
http://www.thelinuxconsultancy.co.uk/phpeditors/
(contributed by Christophe Chisogne).
4. Not sure if PHP is working or you want
find out what extensions are available to
you?
Just put the following code into a file with
a .php extension and access it through your
webserver:
<?php
phpinfo();
?>
If PHP is installed you will see a page with
a lot of information on it. If PHP is not
installed (or not working correctly) your
browser will try to download the file.
(contributed by Teren and reworded by Chris W
Parker)
5. If you are stuck with a script and do not
understand what is wrong, instead of posting
the whole script, try doing some research
yourself. One useful trick is to print
the variable/sql query using print or echo
command and check whether you get what you
expected.
After diagnosing the problem, send the
details of your efforts (following steps 1,
2 & 3) and ask for help.
6. PHP is a server side scripting language.
Whatever processing PHP does takes place
BEFORE the output reaches the client.
Therefore, it is not possible to access
users' computer related information (OS,
screen size etc) using PHP. Nor can you
modify any the user side settings. You need
to go for JavaScript and ask the question in
a JavaScript list.
On the other hand, you can access the
information that is SENT by the user's
browser when a client requests a page from
your server. You can find details about
browser, OS etc as reported by
this request. - contributed by Wouter van
Vliet and reworded by Chris W Parker.
7. Provide a clear descriptive subject line.
Avoid general subjects like "Help!!", "A
Question" etc. Especially avoid blank
subjects.
8. When you want to start a new topic, open a
new mail composer and enter the mailing list
address php-generallists.php.net instead of
replying to an existing thread and replacing
the subject and body with your message.
9. It's always a good idea to post back to
the list once you've solved your problem.
People usually add [SOLVED] to the subject
line of their email when posting solutions.
By posting your solution you're helping the
next person with the same question.
[contribued by Chris W Parker]
10. Ask smart questions
http://catb.org/~esr/faqs/smart-questions.html
[contributed by Jay Blanchard)
11. Do not send your email to the list with
attachments. If you don't have a place to
upload your code, try the many pastebin
websites (such as www.pastebin.com).
