Clean URL on localhost - php

Question

I'm trying to achieve clean URLs on my localhost (so when I write localhost/contact, it redirects me to localhost/contact.php), but it's not working. I did it according to the older tutorial I found on YouTube, but I probably didn't understand well some parts. Many thanks for every answer. Here is my code:
.htaccess // I am sure I have mod_rewrite allowed.
<IfModule mod_rewrite.so>
RewriteEngine On
RewriteBase /www/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1
</IfModule>
Script in index.php
include_once('classes/simpleUrl.php');
$url = new simpleUrl('localhost');
$test = $url->segment(1);
if (!$url->segment(1)) {
$page = 'home';
}
else {
$page = $url->segment(1);
}
switch ($page) {
case 'home' :
echo 'Home page';
break;
case 'contact':
echo 'Contacts page';
break;
default:
echo '404';
break;
}
classes/simpleUrl.php
class simpleUrl {
var $site_path;
function __toString() {
return $this->site_path;
}
private function removeSlash($string) {
if ($string[strlen($string) - 1] == '/') {
$string = rtrim($string, '/');
return $string;
}
}
function __construct($site_path) {
$this->site_path = $this->removeSlash($site_path);
}
function segment($segment) {
$url = str_replace($this->site_path, '', $_SERVER['REQUEST_URI']);
$url = explode('/', $url);
if(isset($url[$segment])) {return $url[$segment];} else {return false;}
return $url;
}

Answer 1

$url = new simpleUrl('localhost');
localhost is not shown in $_SERVER['REQUEST_URI'] so in this case you may simply use $url = new simpleUrl('index.php');
OR
Use this code for .htaccess :
RewriteEngine On
RewriteBase /www/
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^.*$ index.php [L]
because when you do this:
RewriteRule ^(.*)$ index.php/$1
Your actual URL may become something like this:
localhost/index.php/contact
So it's better requested URL to stay same.
but in this case use:
$url = new simpleUrl('');
Oho, look at this mistery:
private function removeSlash($string) {
if ($string[strlen($string) - 1] == '/') {
$string = rtrim($string, '/');
return $string;
}
}
when passed $string does not ends with slash it returns nothing, so have to change it in such:
private function removeSlash($string) {
if ($string[strlen($string) - 1] == '/') {
$string = rtrim($string, '/');
}
return $string;
}
Now I'll explain when and why to use $site_path for simpleUrl constructor:
if you have running your script in subdirectory, for ex: if you are working under /www/test/ then you should you test as param to pass to simpleUrl constructor, otherwise leave it blank
Update 3
You should change simpleUrls segment method to this:
function segment($segment) {
$url = trim(str_replace($this->site_path, '', $_SERVER['REQUEST_URI']),'/');
$url = explode('/', $url);
if(isset($url[$segment])) {return $url[$segment];} else {return false;}
return $url;
}
and next use 0 as index instead of 1 - $url->segment(0)

Answer 2

I'm not sure if you wish to use more variables like: www.domain.com/folder-with-website/products/product-name or if you could live with: www.domain.com/folder-with-website/products?id=123
But try this:
index.php
<?php
$page = $_GET["page"];
if(file_exists("pages/{$page}.php")) {
include("pages/{$page}.php");
} else if(empty($page)) {
include("pages/home.php");
} else {
echo "This page does not exists";
}
?>
.htaccess
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?page=$1
Options -Indexes
Link setup
<ul>
<li>
Home <!-- Just a page without any variables -->
</li><li>
Products <!-- same as Home -->
</li><li>
Details about product <!-- Page with a variable / extra information -->
</li><li>
Details about product <!-- Page with more variables -->
</li>
</ul>
