[SOLVED] Problem With require() and header()

centerwork · November 28, 2007

Here is my problem. My pages use the script below to connect to the database:

<?php
//Establishes A Connection With The Database
require ($_SERVER["DOCUMENT_ROOT"] . "/dir/ssl/config.php");
$connection = mysql_connect($db_host, $db_user, $db_password, $db_name) or die ("error connecting");
mysql_select_db("my_db"); 
?>

When I run any of my pages with a:

header("Location: http://www.mysite.com/dir/somepage.php");

I get this error below.

Warning: Cannot modify header information - headers already sent by (output started at /some_dir/some_file.php:11)

I know this error is caused by having the header() called after something is echo/print.

My file config.php has no header. Here is the Complete File.

<?php
$db_host = "host server";
$db_user = "username";
$db_password = "password";
$db_name = "my_db";
?>

I have figured that the server is echoing out the the html, header, body on its own.

What can I do to just have it load the variables?

output started at /some_dir/some_file.php:11

Start by reading the error message. Whatever the actual file name is, line 11 is where the output was started and since neither of the pieces of posted code has 11 lines, you would need to post the first 12 or so lines of the file that the error message is referring to.

How exactly did you figure this out?

centerwork · November 28, 2007

My file config.php has no header. Here is the Complete File.
<?php
$db_host = "host server";
$db_user = "username";
$db_password = "password";
$db_name = "my_db";
?>  

This is the complete file.

The error stats that this file has already sent a header. See error below.

Warning: Cannot modify header information - headers already sent by (output started at /some_dir/some_file.php:11)

As far as the ":11" If that means lines then it must have the html, header, and body echoed out.

trq · November 28, 2007

Servers don't just spit out headers by themselves. Can wee see some_file.php?

revraz · November 28, 2007

That is config.php. The error is in some_file.php

My file config.php has no header. Here is the Complete File.
<?php
$db_host = "host server";
$db_user = "username";
$db_password = "password";
$db_name = "my_db";

My guess would be that you have 11 or so newlines before the opening <?php tag or after the closing ?> tag.

Here is the full error.

This is the complete db_config.php file.

As far as I can tell the there is no header() after the <head> tag.

This only leaves the db_config.php file.

A version of this file was used on yahoo hosting with no problem. It is now hosted on godaddy. I'm not sure if that helps at all.

My guess would be that you have 11 or so newlines before the opening <?php tag or after the closing ?> tag.

This is most likely correct.

The "complete" db_config.php you posted is only 6 lines long, yet the error is referencing line 11 of db_config.php.

Are you sure you have absolutely no spaces or newlines before the <?php or after the ?> in db_config.php?

centerwork · November 28, 2007

That was it. There were some blank lines & spaces in the db_config.php.

to think that all that was caused by them.

Thank you everyone, that was a big help.
