Hyperlink multi-level sub-directories through index.php? structure - php

Question

I'm trying to create a hyperlink structure that can access multi-level sub folders. For now, I can access my hyperlinks with only one-level (php) directory, such like index.php?content=about (whereas 'about' is about.php).
What I want to do is to create a filing system for a larger website with multi-level sub-directories like the following example,
index.php?blog/category/process/. I don't know if there is a symbol that replaces html symbol / (slash for directory) but for PHP directories. I tried different ways of accessing files inside multi-level sub-directories, such as putting the ? (question mark). It was all hypothetically experimental. If I use the slash, such in the form 'blog/category/process/filename.php', I get a 404 Not Found error.
There is the following PHP script inside function.php, that gets the content from the URL, if there is no content, it sets a default and if there is content, it sanitizes data against hacking:
function loadContent($where, $default='') {
$content = filter_input(INPUT_GET, $where, FILTER_SANITIZE_STRING);
$default = filter_var($default, FILTER_SANITIZE_STRING);
$content = (empty($content)) ? $default : $content;
if ($content) {
$html = include 'content/'.$content.'.php';
return $html;
}
}
function loadIncludes($where, $default='includes/') {
$includes = filter_input(INPUT_GET, $where, FILTER_SANITIZE_STRING);
$default = filter_var($default, FILTER_SANITIZE_STRING);
if($includes) {
$html = include 'includes/'.$includes.'.php';
return $html;
}
}
The link to the document inside 'blog/category/process/filename.php' shows up (where it was '404 Error' before, but the header and the css files do not work. They are not been picked up.
Please note:
My website structure is
Header (one header picked up by index.php?)
Content (multiple content=filename.php)
Footer
index.php looks like this:
<?php
require ('includes/function.php');
require ('includes/init.php'); /* init.php picks up the header */
?>
<div class="clearboth"></div>
<!-- ******** HOMEPAGE ********** -->
<?php loadContent('content', 'home'); ?>
<div class="clearboth"></div>
<!-- ******** FOOTER ********** -->
<?php include ('content/footer.php'); ?>
I found the solution on the structure of the multi-level sub-directories through index.php? that also picks up the CSS, which is as follows:
<a href="index.php?content=blog/category/process/filename">
(leave out the extension .php followed after 'filename')
Thank you for all your help!

<?php
/* FOLDERS STRUCTURE
$_SERVER['DOCUMENT_ROOT'] = C:/Server/www/music; // YES Windows :)
THIS FILE = folders.php
C:/Server/www/music
C:/Server/www/music/files/
C:/Server/www/music/files/folder1/
C:/Server/www/music/files/folder1/folder2/myfile.jpeg
*/
$root = $_SERVER['DOCUMENT_ROOT'];
$requestURI = $_SERVER['REQUEST_URI'];
$startFolder = '/files/';
preg_match('/\?/', $requestURI) ? list($requestURI, $fileToFind) = explode('?', $_SERVER['REQUEST_URI']) : exit('Bad request');
$file = $root.$startFolder.$fileToFind;
if(file_exists($file)){
//YOUR CODE
}
else {
header("HTTP/1.0 404 Not Found");
}
// Usage = http://music.com/folders.php?/folder1/folder2/myfile.jpeg
?>
Read those questions I had asked before. I hope it will help you

Note that you may play with http headers header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found"); or header($_SERVER["SERVER_PROTOCOL"]." 200 Ok"); In case the file exists or not

Answer 2

I found the solution on the hyperlink structure of a multi-level sub-directories through index.php? that also picks up the CSS, and does not issue a 404 Error, which is as follows:
<a href="index.php?content=blog/category/process/filename">
descriptive header
</a>
(note: remember to leave out the extension .php followed after 'filename')
