Will CI 3.x work properly with PHP 8.x?

I have the variable 'terms' used to input search arguments in a form, it is used in 'Model' and 'Controller', CI4. The variable refers to the 'search' field on the form, as shown below:

PHP Code:

<div class="search-container">
 <form action="/search/allmedia" class="site-search" method="post" name="site-search">
 <input class="site-search-button" name="wdeda" type="submit" />
 <input class="site-search-input" name="search" placeholder="Pesquisar" tabindex="1" type="search" />
 </form>
 </div> 


I use the same variable in Model and Controller:

PHP Code:

// Model

public function getNames() {
        $request = \Config\Services::request();
        $db = $this->db;
        $terms = $request->getVar('search');
        $query = $db->table('names')
        ->select('*')
        ->like('name', $terms)
     ->orLike('alias', $terms)
     ->orLike('alias2', $terms)
     ->orderBy('vip', 'name', 'alias', 'asc')
        ->get();
        
        
        if( $query->getResult() != null ) {
        
        return $query->getResult();
        
        } else {
        
        return null;
        
        }
    }

// Controller

 $terms = $this->request->getVar('search');        
        if (empty($terms)) {
            return redirect()->to('/errors/nodata');
            exit;
        }
