PHP - Rookie Progressbar Question

I'm a little confused with the use of absolute paths in PHP.  I've always used relative paths but it's becoming an issue with some of the apps I'm working with and absolute would solve the problem.

The thing is, I'm getting different results in different places and I'm a little confused.

With regular HTML I seem to be able to use / as the root of my site.  So if I do the following...

Code: [Select]
<img src="/images/name.jpg" />
That works fine no matter what page it's called from in the site and no matter what directory that page is in.  I need to be able to do that same thing with PHP.

Now, in my custom 404 page I have the following...

Code: [Select]
if($AddressURL == 'http://www.domain.com/blog/files/filename.zip')
{
header('HTTP/1.1 301 Moved Permanently');
header('Location: /download/filename.zip');
exit();
}

That actually works just fine. If I go to the /blog/files/filename.zip (which doesn't exist) in a web browser it winds up downloading the file at www.domain.com/download/filename.zip as expected. 

Now where I get confused is that include files don't seem to work like that with PHP.  If I do this...

Code: [Select]
require_once('/includes/config.php');

That winds up looking for an /includes folder all the way back at the local server root, not just the web root.  so it's looking for /var/includes instead of /var/www/includes and of course that doesn't end up working.

So, how come the include file paths work differently than regular HTML paths or header redirects in PHP?  Is there any simple way I can always refer to the SITE root no matter what server it's running from?  I've tried playing with $_SERVER['DOCUMENT_ROOT'] but it only seems to return the root of the current document, not the root of the whole site.  So if I use it within a php file located in /var/www/includes/test.php it considers /includes the root which is not what I want.

Any information would be greatly appreciated.  Thanks!

I have been trying to insert data into my database thru php script with no luck. I think its has to do with not being able access my database. My question is when I use MySQL command client and enter the password and get mysql> does that mean I can use that password to access my databases as long as  I point to the correct database with the mysqli_connect function. I dont think I fully understand how this works.  I have everything stored on my local computer and I use "localhost" in mysqli_connect function.

Perhaps a slight trouble, but I can not solve it:   Match only path like: Trainings/1/test.pdf   but dont match one more directory like this: Trainings/1/4/other.pdf   Any suggestions?

Hello everyone.

I'm in the making of a dynamic (hopefully) site to let people browse, listen and download the music I've made through the years, where I can use an upload form (uploading a file + some relevant info) to automatically make a ... song.php?id=*** site. (By now you know, I'm totally clueless )

I've set up a database, an upload form, it's tested, everything works so far (a file gets uploaded to the server, and relevant info is posted to the db).
The problem is, I dont know how to use this effectively.

I'm able to retrieve a Title through searching for a specific artisthandle, like so:

Code: [Select]
$result = mysql_query("SELECT * FROM uploading
WHERE Artist='artistname'");

while($row = mysql_fetch_array($result))
  {
  echo "..: Artistname";
  echo "<br />";
  echo $row['Title'];
  echo "<br />";
  }
But from here on out, I don't know - and I really fail to find tutorials (which have been my only source as of now).

In general, I want my site to, systematically, work much like e.g. www.ctgmusic.com. How is it set up? How do you make ...php/?id='''   pages? How does it work?
What variables or functions do I need to use?

If anyone have an easy-going tutorial on these basics, I would be extatic!
Hope to hear from you

Hi everybody

I am a PHP rookie for now, and
I want to reload the same dynamic page - it's content in several languages - by clicking little flags which are located at some point on the page - AND ITS NOT WORKING.

Clicking on the flag triggers a PHP script which basically says

Code: [Select]

]$_SESSION['lang'] = <Some_language>;
require ('webpage.php');


where webpage.php is the dynamic page, in different languages, with it's content drawn out from a database (which contains the content in all languages I chose to display, blah, blah)
Funny thing - when I look at the page html (View Page Source) - it seems OK (identical from one page to the next) ! But WHAT is displayed after the first attempt to change the language is not.
Is something fundamentally wrong with my approach ?
