Big problem with headers!

[SirChick]

Ok this is a bad problem as I just converting my site to CSS.

 

Now for validation i always header away users.. but now cos i have this:

 

<?php
include css1 file
//php stuff
header("page etc etc ");
include css2 file
?>

 

I am obviously now getting:

 

Warning: Cannot modify header information -

headers already sent by (output started at C:\xampp\htdocs\css\layout1.php:142)

in C:\xampp\htdocs\myitems.php on line 179

 

There must be a work around to this!? Obviously CSS is going to happen first before the php.  Between the two files the php is in a column of the CSS so i have to split it like that... so does this mean i can now only print errors and never header people away?

use a if condition or in bad pratice use ob_start() and ob_flush() at the end off the page

Wait i am using an if condition ..its basically if the $_GET is wrong it has this at the very end:

 

}Else{

Header the page

}

 

No content is shown from the php outside an IF statement. But the CSS is.

 

So what does ob_start() and ob_flush() do? And why is it bad practice?

I put them both at the bottom of the page but nothing happens. Same error occurs i mean.
