friendly url rewrite

Hello, how are you?

I need the url of my homepage to look like this: link url of the home page is appearing like this: link

A second page appears as the initial page: link

I would like the second page to look like this: link ie I would hide the sourceId = 78902565 and in the location of categoryId = 5 there would appear super-offers.

On all other pages, the sourceId = 78902565 appears, I would like to hide it in a way that would not hurt my sales and in the location of categoryId the names of the respective categories appear, such as:

link link

I would like it to appear:

link link

  

My .htaccess looks like this:

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

</IfModule>

  

My index.php looks like this:

<?php
     function getHome(){
    $url = (isset($_GET['url'])) ? $_GET['url']: ('home');           
        $url = array_filter(explode('/',$url));         
        $file = ('pgs/'.$url[0].'.php');

        if(is_file($file)){
               include $file;
        }else{ 
               include('pgs/'.'home'.'.php'); 
        };

        if((null== $file) || ('pgs/'.$url[0].'.php')== '' || ($_GET['url']) === false){
           include('pgs/'.'404'.'.php');  
               exit();      
        };       

     };
     getHome();
?>

Other pages like: contact and about work normally, just for the offers page I need friendly url (s).

Is it correct for these weird url (s) that appear?

Thanks in advance.
