Instead of using ?id=30 - php

Question

and thanks for taking a look to this weird and awkward post.
I have been working on a Cars website for a while (version: 1) wich is pretty basic, now im learning a little bit more about POO so i guess i will be updating it...
I have seen before on a Scripts website that they do this:
Example:
websiteurl.com/scripts/view/300 or websiteurl.com/scripts/view/1761/media/
or websiteurl.com/scripts/view/1761/comments
Im currently doing this:
mywebsite.com/viewCars.php?id=300 but i would like instead of doing that , doing this:
mywebsite.com/cars/view/300
Thanks, and i hope someone understand my question, forgive me for my bad spelling but english isn't my first language.

Assuming you are using apache, soemthiing like this should give you the format you mentioned
in your .htaccess file
----------------------
RewriteEngine On
RewriteBase /
RewriteRule ^cars/view/([0-9]+)$ viewCars.php?id=$1 [NC,L]

Answer 2

have you heard about htaccess. Check the documentaion. You can sole your problem by using htaccess and some regular expresion. Here is an example solution for your question.

If you are using a MVC architecture, you could do something like this:
function __construct() {
$url = isset($_GET['url']) ? $_GET['url'] : null;
$url = rtrim($url, '/');
$url = explode('/', $url);
if (empty($url[0])) {
require 'controllers/index.php';
$controller = new Index();
$controller->index();
return false;
}
$file = 'controllers/' . $url[0] . '.php';
if (file_exists($file)) {
require $file;
} else {
$this->error();
}
$controller = new $url[0];
$controller->loadModel($url[0]);
// calling methods
if (isset($url[2])) {
if (method_exists($controller, $url[1])) {
$controller->{$url[1]}($url[2]);
} else {
$this->error();
}
} else {
if (isset($url[1])) {
if (method_exists($controller, $url[1])) {
$controller->{$url[1]}();
} else {
$this->error();
}
} else {
$controller->index();
}
}
}
