php include statement

I'm working on my first website using php. I came up with a good way, or so I thought, to deal with including the css sheet depending on where I am. For example, I have a form that I submit to with this code:

 $root = '../';


 function died($error) 
 {
  include '../includes/header.php';
  echo "We are very sorry, but there were error(s) found with the form your submitted. ";
  echo "These errors appear below.<br /><br />";
  echo $error."<br /><br />";
  echo "Please go back and fix these errors.<br /><br />";
  include '../includes/footer.php';
  die();
 }

I set the variable $root to have "../" and then here is the relevant part of header.php:

<link href="<?php echo $root;?>styles/styles.css" rel="stylesheet" type="text/css" />

I would think that it would put in "../" in front of styles, but it doesn't put anything. Why doesn't this work?

Thanks!

$root is not in scope for the function (im assuming..) add global $root; to the top of the function and it should work.

$root = '../';

function whatever() {
  global $root;

  echo "<link rel=stylesheet type=text/css href=\"" . $root . "something.css . "\">";
}

For referencing files such as this you simply need to start the path with a forward slash and the path is then relative to your root directory...

<link href="/styles/styles.css" rel="stylesheet" type="text/css" />

In this situation my suggestion is to use $root = "FULL path";

So for example... if your web root is in "/var/www/html/" and you are working on a project lets call it sampleProject which is in "/var/www/html/sampleProject".

Set $root="/sampleProject/; and this way when you use things such as styles/styles.css"/> you end up with which is what you want.

Unlike other answers this makes your code more portable in my oppinion. For example if you move your site "sampleProject" to /var/www/html/dir1/dir2/dir3/sampleProject/ all you need to do is change $root="/dir1/dir2/dir3/sampleProject/" and it will still work. Whereas if you use explicit full path as some suggest you will have to change this everytime you move your site.

You can make the path to your CSS file absolute:

<link href="/styles/styles.css" rel="stylesheet" type="text/css" />

Prefixing a URL with a forward slash (/) will make the URL relative to your site's root. The above example would reference something like http://example.com/styles/styles.css. This way, you can put all your CSS in a folder at the root of your site and not have to worry about the path at all.
