Headers already sent?

[NoEffinWay]

hi, I made a style sheet that the content is generated via SQL info. It woks fine on test servers in the office, but on a live site, it always says the headers are already send.

Warning: Cannot modify header information - headers already sent by (output started at /home/df420/public_html/somedir/template/style.php:1) in /home/df420/public_html/somedir/template/style.php on line 1

And here is the first 50 lines of the file.

<?php header('Content-type: text/css');
require_once('../includes/settings.php');
require_once('../includes/db.inc.php');
require_once('../includes/style.inc.php');
$s = $style->getStyle();?>
/* Dynamic CSS Document */
html{
<?php
foreach($s['html'] as $a){
    echo $a['attribute'].':'.$a['value'].';'."\n";
}
?>
}
body {
    font-size: 10pt;
    margin: 0 0 0 0;
    font-family: Myriad Pro, Tahoma, Verdana, Arial, Helvetica, sans-serif;
}
h2{
<?php
foreach($s['h2'] as $a){
    echo $a['attribute'].':'.$a['value'].';'."\n";
}
?>
}
h3{
<?php
foreach($s['h3'] as $a){
    echo $a['attribute'].':'.$a['value'].';'."\n";
}
?>
}
th {
    text-align: left;
}

td {
    padding: 0px 0px 0px 0px;
}

div.main {
    width: 1000px;
    margin: 0px auto 0px auto;
}

td.top_left {
    background: url("../images/template/top_left.png");
    width: 244px;
    height: 157px;
}

If the file is saved as UTF-8, make sure it is saved wtihout a BOM (byte order mark), which would be output before your opening <?php tag (or just save it as plain ASCII text if you don't really need the extended UTF-8 character set).

If that's not it, is it possible your web host has an auto_prepend_file configured in your php.ini settings (or apache config/.htaccess) which might be generating output?

Awesome, it was the encoding. Thanks a lot.

EDIT: Just out of curiosity, why would it be fine locally and not work remotely?

Possibly something to do with the FTP client or file upload page you used to deploy it to the web host?
