[SOLVED] Simple GETENV and string manipulation?

[raif]

Example URL:

 

http://www.anyolddomainname.com/myfolder/subfolder/folder_name_of_changing_length/one_of_four_names.php

 

Element required :

 

folder_name_of_changing_length

 

Accepting that only the first part of the URL is fixed (http://www.anyolddomainname.com/myfolder/subfolder/), how do I obtain 'folder_name_of_changing_length' ?

 

 

I'm have a script that I've written that is not especially elegant. Its objective is to generate a menu that includes links that carry variables based on querying a database dependent on the folder name and the file name. I started with this:

 

<?

include_once('../includes/db_connect.php');


$url_ext = getenv('SCRIPT_NAME');

$start_string = substr($url_ext, 0, 20);

$end_string = strtok(getenv('SCRIPT_NAME'), "/" +1);

$end_string = substr($end_string, strrpos($end_string, "/"));

$pattern = '/\/myfolder\/subfolder\//';

$replacement = "";

$final_string = preg_replace($pattern, $replacement, $url_ext);

$apattern = '/\//';

$areplacement = "";

$afinal_string = preg_replace($apattern, $areplacement, $final_string);

//echo $afinal_string;

if ($end_string == '/one_of_four_names.php') 

{

$newpattern = '/one_of_four_names.php';

$newreplacement = "";

$folder = preg_replace($newpattern, $newreplacement, $afinal_string);

$result = mysql_query(...... 

 

I'm using strtok, substr, preg_replace with IF, ELSE IF

 

This works but seems a little clunky!? I looked through the pages here and Googled the subject but can't find anything obvious. I've also read the guidelines about posting these kind of questions and hope that I'm not off the mark with my query.

<?php

$url = $_SERVER['REQUEST_URI'];
$url_parts = explode('/',$url);

$folder = (count($url_parts)>1) ? $url_parts[0] : 'No folder it is just a file from the root dir' ;

?>

 

That should get you the changing length folder...

That's great! Thanks kathas! You can see I'm just trying to get a handle on this stuff. I guessed there was probably a simple approach - such is life as a newbie...  Thanks again!

Just to let you know - I've implemented that and it's cut my script down very nicely indeed! Smaller file and quicker processing Cheers

Thanks... i just read your code and i see you used regular expressions... you should know that they are the slowest string search... they should only be implemented if there is no other way (which is in fact many times)...
