PHP :: Generating HTTP Header Error Codes

Error Reading WWW Server Response (HTTP Header). Error Code: 0
I have been trying out the web based email program on this website to connect to a pop 3 client...it worked ok...but now when i try to logg in all i get is this error message...on the page Error occurred!

Description: Error reading WWW server response (HTTP Header). Error code: 0(0 = client terminated the connection unexpectedly, 2 = too many header lines) Code:

Get Http Response Codes
I have a website in php in which I have some kind of portal to external
links that come from a database. When a user clicks on a link,
"link.php" is called, does some stuff (e.g. adds 1 to the visit-count
of that certain page) and then forwards the user with a location-header
to the asked page. Now my question: is it possible to get the
response-code of that asked page? E.g. when code 404 is returned, I
can put that in the database and then it's easy for me to know when a
link is broken.

Sending HTTP Codes
How can i send a http response code 200 to google checkout? Obviously I have the url to send to!

Getting HTTP Status Codes For Web Pages Through Proxy
I'm having a terrible time trying to get HTTP status codes from web pages (404, 200, 301, etc.). I think a big part of the problem is that we're behind a proxy.

How would I modify the following code examples to connect through a proxy in order to get the status code?

function http_file_status($url, $followRedirects = true)
{
$url_parsed = parse_url($url);
if (!@$url_parsed['scheme']) $url_parsed = parse_url('http://'.$url);
extract($url_parsed);
if(!@$port) $port = 80;
if(!@$path) $path = '/'
if(@$query) $path .= '?'.$query;
$out = "HEAD $path HTTP/1.1";
$out .= "Host: $host";
$out .= "Connection: Close";
if(!$fp = @fsockopen($host, $port, $es, $en, 5)){
return false;
}
fwrite($fp, $out);
while (!feof($fp)) {
$s = fgets($fp, 128);
if(($followRedirects) && (preg_match('/^Location:/i', $s) != false)){
fclose($fp);
return http_file_status(trim(preg_replace("/Location:/i", "", $s)));
}
if(preg_match('@HTTP[/]1[.][01x][s]{1,}([1-5][01][0-9])[s].*$@', $s, $matches))
{
$status = $matches[1];
}
}
fclose($fp);
if(!empty($status))
{
return $status;
}
return false;
}

OR:

set_time_limit(20);
ob_start();
header("Content-Type: text/plain");
$host = "www.webmasterworld.com";
$port = 80;

$post = "HEAD / HTTP/1.1";
$post .= "Host: www.webmasterworld.com";
$post .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2";
$post .= "Keep-Alive: 200";
$post .= "Connection: keep-alive";
$sock = fsockopen($host, $port, $errno, $errstr, 20.0);
fwrite($sock, $post, strlen($post));

while (!feof($sock)){
echo fgets($sock);
}
ob_end_flush();

Sending Error Codes
I am having trouble sending error codes to the
browser from my php page.

I want to send a 401 Unauthorized, and a 404 not found.

I have tried these (in seperate documents):

header("HTTP/1.0 404 Not Found");
header("Status: 401 Unauthorized");

I put a single header at the top of the page
but I received a blank document in return.

What else do I have to do send error responses
in PHP?

HTTP HEADER
Can someone give me the code snippet to create a header for php to implement the download dialog box.

HTTP Header
I've got a question concerning the headers sent by the client accessing your page. I have found there are several variables accessible in PHP:

$_SERVER['REMOTE_ADDR'] (which should not be determined by any HTTP headers, but by the web server reading the TCP/IP headers, right?)
$_SERVER['HTTP_VIA'] (which will be filled if there is a transparent proxy)

the above are pretty clear and cause no problems. But when you continue to search for headers that can possibly be sent by a client (may it be a proxy or not), it's getting very confusing:

$_SERVER['HTTP_X_FORWARDED_FOR']
$_SERVER['HTTP_CLIENT_IP']
$_SERVER['HTTP_PROXY_CONNECTION']
$_SERVER['FORWARDED_FOR']
$_SERVER['X_FORWARDED_FOR']
$_SERVER['X_HTTP_FORWARDED_FOR']
$_SERVER['HTTP_FORWARDED']

I mean, they all seem to denote the SAME thing. Why use SEVEN different headers for that? Were the guys who wrote the RFCs bored? Why confuse people with so much possible headers, when it could be in ONE SINGLE header?

Apparently this is not a PHP problem, since PHP just fills these variables by reading the HTTP header lines (X-Forwarded-for: , X-Forwarded: , ...) sent by the client.

I have googled for all of those, but opinions seem to differ on what header line should be taken into account and what header line shouldn't.

So,
1) Why are there so many possible headers? Are some of them obsolete?
2) What is the difference between those headers with a 'X' and those which lack the 'X'?
3) What is the difference between "FORWARDED_FOR" and just "FORWARDED"?

Header Error Without Whitespace Issue - Cannot Modify Header Information

HTTP Header Errors
Has anyone experienced random incomplete HTTP header errors? It seems to
happen randomly, say 1 in 100 page loads but that is just the ones I
see. I'm running version 4.2.3.

Set HTTP Header In NuSOAP
I'm developing a PHP client that consumes a Web Service written in
Java-Axis. I'm using NuSoap toolkit.

Now I have the need to send IPaddress (together with the SOAP request) to
the Web Service ...
Is there a chance to include client IPaddress to SOAP request?
I'd like to include it in sucha a custom HTTP header stored as
X-IPAddress...
Is there any method in nusoap to set http header and include in it
IPAddress?

How To Get Http Header Infomation Using PHP?
Is there any way to get all the information in HTTP header? I want to
get a item called "Referring URL" in HTTP header. I find the information
is not contained in the environment global variable $_SERVER.

What Is The Raw Http Header To Send A Cookie
I am using fsockopen to communicate with an internal web server. It uses a cooke for authenticaion.

When I make the first request I get the cooke but don't know how to send it back... in other words how does the browser do it.

BTW, please don't suggest setcookie(), that has nothing to do with my problem.

Viewing Entire HTTP Header ?
is there a way in code to view the entire HTTP Header? Many of the
variables in $_SERVER have much of the header, as do some of the apache
functions, but none seem to have a way to show the body that was sent with
the request.

any suggestions for how i would go about doing this? It's mostly for
documentation and instructional purposes, but i'd like to see the results
without having to construct them by hand and telnet'ing into port 80 all
the time ....

Fsockopen() Sending HTTP POST Header
I recently learned how to use fsockopen() to send a POST HTTP header and read the response, and I have done this successfully to get a rate zone table from the UPS Web site, having sent the origin ZIP code as one of the variables.

I am now working on a completely separate project and trying to send a POST header to a test page on the server on which I am developing, and I have run into a snag. The fsockopen() function is connecting to the page specified in the POST header, but it doesn't appear to be receiving any of the variables. Code:

Convert HTTP Header Last Modification Date To Integer

HTTP Header Response For Invalid Form Inputs?
Is it necessary or is there any standard to send HTTP header status
for form inputs ? Say, the user is entering invalid password in login
form and now all the applications I have seen are just displaying error
messages above the form (with HTTP status 200); is it necessary to send
401 status in this case?

Adding Own HTTP Header Fields Along With A SOAP Request In PHP
PHP scripting and i am trying to connect to a soap server
(as mentioned below) using the SOAP extension comesup with PHP. Now my
requirement is to add my HTTP header fields along with my SOAP request,
so that the SOAP server will receive it and does some high level
processing. Is it possible to add our own HTTP header fields in PHP?
If i use the header() function to add the field into the HTTP header
and it neither reports an error nor adds it to the headers list.

<?php
header("X-Test: foo");
setcookie('foo', 'bar');
/* Define a custom response header */
header("X-Sample-Test: foo");

$client = new SoapClient(NULL,
array(
"location" => "http://127.0.0.7:3490",
"uri" => "urn:calc",
"style" => SOAP_RPC,
"use" => SOAP_ENCODED,
"trace" => 1
));
$client->__setCookie("Auth",$tem);
echo ($client->__call(
"add",
array(
new SoapParam(
10,"a"),new SoapParam(22,"b")
),
array(
"uri" => "urn:calc",
"soapaction" => "add"
)). "
");
//echo $client->requestheaders();
var_dump(headers_list());
?>

Imagejpeg Generating String Not Image Even With Header("Content-type:image/jpeg")
does anyone know why i can't generate images with:
header("Content-type:image/jpeg");
imagejpeg($img_number);

i've tried different examples but i always get a text output as if the
header doesn't make a difference at all.

<?php

CGI And HTTP Headers Error
My PHP script produce an intermittent CGI error. The sequence of events is:
1- User load page A to login

2- Submit page A redirect (with the PHP funciton header("Location:
http://www.mydomaine.com/mydir/b.php") to page B.

3- About 20% of the time I got the error:
"The specified CGI application misbehaved by not returning a complete set of
HTTP headers."

4- "Refresh" afterward shows the page without error.

I tried to find a difference between a correctly loaded page B and one that
generate an error and I cannot find one. It realy doesn't seem to be linked
to the sequence of action the user is doing.

Header Error
This error is being produced with the following code. I know that the header code is messing with it and causing it not to work, but why is it not redirecting like it should? The code in question is right after the insert query.

"Cannot modify header information - headers already sent by " and have tried to follow their suggestions.

Bad Header Error
I have a simple send mail script that is causing an internal error. I had exactly the same script on another server and it worked perfectly. I think the reson it is not working is because the new server runs php as cgi (have had other problems with very simple scripts working on the previous server but not on the new one) but I am not sure.

Header - Cookie - Session - Error
I am having a problem when I add a include() header and start a cookie session or header control like browser catch. I get the damn errors saying cannot start cookie session header already stated.

So I deleted the include(header) I know this can be done because phpBB board has the same thing.. include(Header.php)even required(config.php) which has the cookie statement.

Header Error Using Redirect Scripts
I'm working on a site for a racquetball goods company where sponsored players can sign in each year using a unique player number. Before they can order their equipment for the year, they have to do three things; enter/update their personal information (personal.php), fill out fields in the contract (contract.php), and complete a questionaire on their home club (questionaire.php).

Once that is done, they will get to a menu page where they can order equipment, go back and update personal informa tion, and do other things. They way I'm controlling this is by using three Y/N fields in the player table that indicate whether or not these three steps have been completed. Once each step is completed, the appropriate field is updated, and they go to the next step. When all three steps are complete, they will be taken to the menu page.

This way, they can't get to the menu page until the three steps are complete, and if for some reason they bail between the first and second steps or between the second and third steps, when they log back in, they just pick up where they left off.

After reading through old posts on sessions and using header() to redirect the user to the appropriate page, I decided to use a couple redirect scripts for processing the form. So, for instance, when the user first logs in, redirect.php looks in the database to see which steps have been completed and redirects the user to the appropriate page. Here is the code:

Cannot Modify Header Information Error
I am having an issue with an php error I am receiving. I have a page that works on an older version of php running on a server which is 4.3.1. However, on another server running php version 4.4.4, that same page returns the following error.

Warning: Cannot modify header information - headers already sent by (output started at /home/thegr29/public_html/headerinclude.php:6) in /home/thegr29/public_html/media_videos/retrieve.php on line 315

The page is setup so that there is a header include, a retrieve file, and a video include. The retrieve file checks for a matching city and state and includes the video include file. In the video include file, the matching city and state is then used to load the correct html which will be echoed out to the page. Code:

Server HTTP Sends Or Streaming HTTP?
I was wondering if you guys had any ideas to constantly
stream a webpage in case an announcement was posted
or possibly pushing onto the browser information.

What I basically want is for a user browsing my website
to be notified of any new announcements. I thought
about checking everytime he changes pages but then
I realized that I want them to be notified as long as
they have the page open even if it's minimized. So it
would at best be a method to use php force send a msg
after someone posts an announcement.

Questions About HTTP Headers Sent With PHP In HTTP Authentication
Here is an example from the PHP Manual

<?php

if ((!isset($_SERVER['PHP_AUTH_USER'])) || (1==1)) {
header('WWW-Authenticate: Basic realm="My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo 'Text to send if user hits Cancel button'
exit;
} else {
echo "Hello {$_SERVER['PHP_AUTH_USER']}.";
echo "You entered {$_SERVER['PHP_AUTH_PW']} as your password.";
}
?>

Questions.

1. This is a status code not a header, right? = header('HTTP/
1.0 401 Unauthorized');

2. According to the change log in the PHP manual, starting with 4.4.2
and 5.1.2 the header function now prevents more than one header to be
sent at once as a protection against header injection attacks. Does
this mean if I make multiple header calls the headers will be sent in
multiple response messages to the browser? Is this allowed? Can a
server send multiple response messages to one request?]

3. If you hit the "cancel" button on the browser user name/password
request dialog (as alluded to in the code snippet above), what message
does the browser send to the server.

Error Using Header("", FALSE) To Show Multiple Images From MySQL Db
Many people seems to have problems when displaying multiple images from their database (mySQL db). Often you can read error statements like "Header already sent out ...". To solve this, people often propose to use include files.

To keep the scipt it would be nice not having this problem, being able to sent out multiple headers to a browser without getting these error messages. In the PHP4 manual, we can read an option that can be added to the header statement, Header("xxx",FALSE). It would enable multiple headers to be sent out.

For instance the following statement:

while ($product = db_fetch_object($result)) {
header("Content-type: pv($product->filetype)",false);
echo pv($product->image)"
}

However, it doesn't work. Anybody has any idea why? Does anybody use this option FALSE with success?

Zip Codes
I have a script that will cross check a form variable against existing variables in a database and redirects visitors based on that, but, I'm also looking to extract the corresponding fields associated with the form variable and inserting that into another form that the visitor may be directed to.

I understand this will most likely be an if/else statement, that says something along the lines of PHP Code:
