Re: [PHP] Problem...header already sent by

Hi Jason,
  Yeap, I ran 'phpinfo()' Server API=CGI.  I look at the manual and you are
right, I must run it as Apache module.  Can someone tell me how do I change
the setting to run as an APACHE module instead?

Thanks,
-Peter

 Are you running PHP as a CGI? If so, what you want to do cannot be done.
See
 chapter HTTP authentication with PHP.

Well, you don't change the setting as such. On a Linux system you would've 
have to recompile PHP and possibly Apache as well. On a Windows system you 
would probably just download the relevant files and install.

Ryan,
   I just tried it with my Linux box and I get the authentication 
box...which is good sign.  So it looks like a PHP in MS Windows (the 
'fabulous' windows) setting which from the error.log file indicates as well.

/** error message listed in error.log **/
[Mon Feb 04 22:36:30 2002] [error] [client 127.0.0.1] malformed header 
from script. Bad header=HTTP/1.0 401 Unauthorized: /apache/php/php.exe


In looks like a setting problem in some .ini file.  Do you know how to 
correct this problem?

Thanks for the help!
-Peter

Hello again Peter,

I describe my reply below.

 I must run it as Apache module.  Can someone tell me how do I change
 the setting to run as an APACHE module instead?

I'll be replying to this question in a Windows Operating System setting. You
have 2 option in installing PHP as in Win OS, either to use the executable
installer less than 1MB file size or to use the zip file almost 4MB file
size (I recommend to use the zip file installer since its more complete
interms of modules and othre dlls).

Unzipped the zip file into any directory you want then just read and follow
the instruction found on the install.txt file. The install.txt file also
indicated how to install PHP as a module on Apache, a minor changes on the
httpd.conf must be made. The install.txt file will tell you how.

Until then

Regards,

Ryan F. Bayhonan

Hello Peter.

I discribe my reply below:

 **
 Warning: Cannot add header information - headers already sent by (output
 started at C:\apache\htdocs\proj\sports\phps\verify.php:2) in
 C:\apache\htdocs\proj\sports\phps\verify.php on line 26

This warning message appear when the server already send data to the client.

 1. html
 2. ?php
 


  23.   if (!$auth) {
  24.  header(www-Authenticate: Basic realm='Private');
  25.  header(HTTP/1.0 401 Unauthrized);
 ...
 ?
 /html

In the above code, the html/html tag has been sent to the client browser
already, thus when calling header function it would cause a warning telling
you that data has been rendered already.

Hope this help.

Re: [PHP] Problem...header already sent by

[Ryan F. Bayhonan]

Hello Peter. Good Day.

Omitting html/html does not solve the problem. I've experience this
problem also before. I found out that the once causing the problem is when
any data that has been sent to the client. I have listed some example below.

Examples: All of these will cause a warning when header is called.

1. Since the tag html will be interpreted by the client browser first
before the ?php ... ? tags, data has been sent to the client, telling the
client that an html file is being rendered. So when the browser interprets
the header function, a warning will be issued.

html
?php
header( some parameters );
exit;
 ?

2. This will also cause an error. Remember that a call to an echo or print
function will send data (the parameters of the function) to the client. So
when the header is interpreted, a warning will be issued.

?php
echo Some text;
header( some params );
exit;
?

Hope this is clear to you now. When a data has been sent already to the
client, a call to a header will fail. The best thing you must do is to put
the logic/check part on the first line of the file (See below). In the
example below, I check first is the a user is valid by calling the the
function verify_user( params... ) before any other html tags be rendered. So
when the user is not valid it will redirect an error page, if it is valid,
the Welcome to page will be printed.

?php
 session_start();
 include 'include/config.inc';
 include 'include/pgsql.inc';

 if (!verify_user($username, $Password, $c_id))
 {
  session_register(isValid);
  $isValid=false;
  $title = Web-based Training System Login;
  $msg = Access Denied!!!;
  $link = ../../index.php?id=.$c_id;
  header(Location:
notify2.php?title=.urlencode($title).msg=.urlencode($msg).link=.urlen
code($link));
  exit;
 }
?
html
body
Welcome to the page.
/body
/html

Hope this help you more.

Until then...

Ryan F. Bayhonan

 2. This will also cause an error. Remember that a call to an echo or print
 function will send data (the parameters of the function) to the client. So
 when the header is interpreted, a warning will be issued.

 ?php
 echo Some text;
 header( some params );
 exit;
 ?

 Hope this is clear to you now. When a data has been sent already to the
 client, a call to a header will fail. The best thing you must do is to put
 the logic/check part on the first line of the file (See below). In the
 example below, I check first is the a user is valid by calling the the
 function verify_user( params... ) before any other html tags be rendered.
So
 when the user is not valid it will redirect an error page, if it is valid,
 the Welcome to page will be printed.

 ?php
  session_start();
  include 'include/config.inc';
  include 'include/pgsql.inc';

  if (!verify_user($username, $Password, $c_id))
  {
   session_register(isValid);
   $isValid=false;
   $title = Web-based Training System Login;
   $msg = Access Denied!!!;
   $link = ../../index.php?id=.$c_id;
   header(Location:

notify2.php?title=.urlencode($title).msg=.urlencode($msg).link=.urlen
 code($link));
   exit;
  }
 ?
 html
 body
 Welcome to the page.
 /body
 /html

 Hope this help you more.

 Until then...

  Hi Ryan,
I tried and took the html/html tags out and I still get the same
  messaage.  Why?
 
  Thanks,
  Peter
 
 
   Hello Peter.
  
   I discribe my reply below:
  
**
Warning: Cannot add header information - headers already sent by
 (output
started at C:\apache\htdocs\proj\sports\phps\verify.php:2) in
C:\apache\htdocs\proj\sports\phps\verify.php on line 26
***
  
   This warning message appear when the server already send data to the
  client.
  
1. html
2. ?php

   
   
 23.   if (!$auth) {
 24.  header(www-Authenticate: Basic realm='Private');
 25.  header(HTTP/1.0 401 Unauthrized);
...
?
/html
  
   In the above code, the html/html tag has been sent to the client
  browser
   already, thus when calling header function it would cause a warning
  telling
   you that data has been rendered already.
  
   Hope this help.
  
   Ryan

[Ryan F. Bayhonan]

It will work as expected Peter.

?php
header (WWW-authenticate: Basic realm=\Private\);
header (HTTP/1.0 401 Unauthorized);
echo Unauthorized;
exit;
?

So where do we go from here??

Ryan
