default root folder path

I have a site that has a variable that holds the path of the root level for each page. It sometimes gives google errors and I want to update it and know there is some kind of better way to reference in PHP. Any tips would be great. currently it looks like this:

img src='<php echo $basePath; ?>images/something.jpg

 

Make a PHP file say, path.php with the following Codes:

<?php
$abspath = dirname(__FILE__).'/';
echo $abspath;
?>

PHP:

Now place the file on the root of your site and run it through your browser. Now copy the output! Say it is

/home/yoursite/public_html/

Code (markup):

Copy it and place the following code, in the file where you have previously stored the variable for the absolute path:

define(ABSPATH, '/home/yoursite/public_html/');

PHP:

Now all you need to do is use the constant string instead of the variable string. Say

$my_img = '<img src="'.ABSPATH.'images/img.jpg" />';
echo $my_img;

PHP:

 

Oh yaa that's true! Mann I did replied as a dumbo :|

 

The following code should work to get the Root directory [Browser type] of any page!

<?php
$site_url = 'http://'.$_SERVER['SERVER_NAME']; //The URL of the main site... Say http://forum.digitalpoint.com
$cur_dir = $_SERVER['REQUEST_URI']; //The other part of URL of the current page... say /showthread.php
$root_dir = dirname(dirname($cur_dir)); //Go one level up the current directory
//Basically the first dirname gives the directory of the current file/page and the second one moves up one level
$root_url = $site_url.$root_dir.'/'; //Concatenate the strings to make the browser URL of the root directory
define(ABSPATH, $root_url);
$my_img = '<img src="'.ABSPATH.'images/img.jpg" />';
echo $my_img;
?>

PHP:

Sorry for the previous wrong post! Actually I did wrote a tutorial on it before. You may want to see this to clarify your doubts!

I hope I haven mistaken anything this time

 

thank you!
