header() function

Anon

Hi, I have the following script in a file at eg. http://www.mysite.com/jump.php3

However, it displays the following information.

Warning: Cannot add more header information - the header was already sent (header information may be added only before any output is generated from the script - check for text or whitespace outside PHP tags, or calls to functions that output text) in /home/ace/aceofdeals-www/test.php3 on line 4

Can anyone tell me what's wrong and how to fix it?

thanx

Hi
The Header-Function must be used before
any character is printed out.
In your example, the browser would
show the text <BODY> and then tries to
use the header-funtion.
U only can use the headerfunction
immidiatly at the beginning, e.g.:
<?php
header("...");
?>

The <?php has to be exactly the beginning
of the file, no space, no tab , nothing

But u can use some php-functions to
evaluate some things before the header,
e.g. reading the IP of the user and
then jumping to different pages !

I see, but what if I want to pass some information from my database to the PHP script?
for example, this is my script :

<?php //beginning of script

$db = mysql_connect("localhost", "myroot", "mypassword");
mysql_select_db("mydatabase",$db);
$result = mysql_query("SELECT * FROM linkdata",$db);
$myrow = mysql_fetch_array($result)
header("Location: %s", $myrow["link"]);
exit();
?>

the browser says something is wrong with the header line I believe. I'm not sure if i'm missing an id number, but say I only have one link in my database.

Did you ever get an answer to this question? I'm debugging it now and can't seem to find where I'm outputoing anything after the header tag?
