I have this code on my header.php. Its for creating title on the fly. The problem is that it only creates a title when user is on the article.php(page for reading the article) but produce a 'undefined variable i' error on other pages. What should I change or who know a better code for the title of web page? i is id.
if(isset($i=$_GET['i']) && $i = true ) {
$i=$_GET['i'];
$tbl_name="yote";
$sql=mysql_query("SELECT * FROM $tbl_name WHERE i='$i'") or die(mysql_error());
while($rows=mysql_fetch_array($sql)){
$title = $rows['title']. "";
}
mysql_close();
} else {
$title = 'Malloooo - News, Reviews, Analysis and Market Watch From Around The World';
}

Honestly, there's quite a bit wrong with your code.
if (isset($i=$_GET['i']) ... : Not sure what you're trying to do with that, but it's not valid.
... && $i = true) : This is setting a value, not checking it.
You're horribly vulnerable to SQL injection. Look into PDO: http://php.net/PDO

My website loads perfectly on Firefox, but the CSS disappears completely on Chrome (although the html loads).
According to the console, this seems to be because Chrome is loading the contents of index.php into main.css and bannerTest.css like so:
On Firefox, however, it loads the CSS as expected:
Things I have tried that did not work:
clearing my history/cache/cookies
adding text/css to the tags. All this did was make the text render a
little weirdly on Firefox.
css and html validation. I fixed all the semi-colons and such. Still doesn't work.
What's the problem? I can't even figure out what steps to take to investigate what's going on more deeply, let alone figure out the problem itself. No errors are printed to the console as far as I can tell.
Here is index.php:

You misdiagnosed the problem. It is due to visiting different URLs to load the HTML document rather then using different browsers. You just switched browsers at the same time as you switched URLs.
Look at the URL that is being loaded in your first image:
http://localhost/peergroup/index.php/css/main.css
In Chrome you must be visiting http://localhost/peergroup/index.php/ while in Firefox you are visiting http://localhost/peergroup/index.php (without a / at the end).
This is causing relative URLs to be computed differently.
A workaround is to use URLs that are relative to the site root (i.e. starting with a /).
I'm having some trouble with IE8 recognising some CSS that is generated from a PHP file and then included in my sites header. This CSS works perfectly in all other browsers I've tested but it simply won't apply in IE8.
If I move the dynamic CSS into my main css files - it works fine.
By dynamic, I mean the the CSS is generated from PHP. I'm already using respond.js to enable media queries in IE8 which is working because if I put this CSS in my main file - the CSS works.
However, if I put non-media query styles in the same file - it does apply. So this must be an issue with respond.js not seeing that responsive CSS.
When I 'View Source' the file has definitely included as it's printed in there but for some reason IE8 won't apply the styles. It doesn't show in Developer Tools.
Basically, the CSS should display a black menu bar at the top of the page when the browser window is narrower than 782 pixels.

This one has me stumped - I've been Googling for an hour which brought up suggestions of changing my DOCTYPE, making sure my comments are ended properly etc but nothing has worked so far.
I suppose that by "dynamic CSS" you mean CSS media queries. If so, the answer is very simple:
IE8 does not support media queries.
There are some JS polyfills that solve the issue, the most famous one is perhaps respond.js.
EDIT
From the discussion in comments: It seems that the issue is caused by the fact, that Respond.js can read CSS from linked stylesheets only, not from inlined CSS.
This question already has answers here:
PHP DOMDocument error handling
(5 answers)
Closed 9 years ago.
I would like to have different outputs if the file is called by Ajax or not.
For that I have this code witch works fine:
/* AJAX check */
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
$content = get_content();
die($content);
}
my function for filtering the contend is this:
function get_content(){
//$file = file_get_contents('index.html'); //works better but i get only errors
$dom = new DomDocument();
$dom->loadHTML($_SERVER['REQUEST_URI']); //or $file
$section= $dom->getElementsByTagName('section');
return $section->item(0)->nodeValue;
}
my output is always empty.
Whats wrong here?
!!!I'am not looking for DOMDocument error handling!!!!
What I do for now is:
/* decide what the content should be up here .... */
/* AJAX check */
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
/* if ajax, show only content of the section tag */
$file = file_get_contents($_SERVER['SCRIPT_FILENAME']);
$section = preg_replace("/.*<section[^>]*>|<\/section>.*/si", "", $file);
die($section);
}
/* not ajax, show page.... */
and it seems to work. I do not know it is the best solution because somewhere in this forum I read that its better to realise that with DomDocument().
Any suggestions are welcome?

You can turn the errors of by setting internal errors to true:
$doc = new DOMDocument;
$before = libxml_use_internal_errors(true);
$doc->loadHTML($html);
libxml_use_internal_errors($before);
You then won't have the errors logged any longer. In your case most likely you've got display errors enabled which might be okay for development, but on your production server, please switch to error logging otherwise your website would reveal too much data to the outside.

Your header is showing but your code is wrong. You need to add your script inside of a no conflict wrapper for it to work properly. And if you are going to add any type of javascript I would consider adding it to the functions.php section so that it enqueue's appropriately.
Reference: http://codex.wordpress.org/Function_Reference/wp_enqueue_script#Link_a_Theme_Script_Which_Depends_on_jQuery

I know that you resolved your issue from my comments.but here it is as answer.
As you asked where you put session_start to remove header already sent error.
As general practice, put session_start() at the starting of your php file. also need to clear previous bufffer.
ob_start(); // this will clear output buffer
session_start();
It appears the error is caused by header("Location: login.php"); - the error says common.php is sending headers already on line 77. It will keep doing this as long as common.php is sending the headers.
Warning: Cannot modify header information - headers already sent by (output started at /home/megatron/public_html/ncms/index.php:9) in /home/megatron/public_html/ncms/common.php on line 77
Without knowing the contents of that file I can't help you. I'd suggest just looking through that file for something sending some headers and see if it necessary or approach this problem differently.
