Links do not have a discernible name
Solution to the problem - to use 
aria-label="Twitter"
attribute on 
a
tag
<a href="<?=$hostname?>" aria-label="Sibrdzne" class="bg-logo"></a>

Form elements do not have associated labels
Solution to the problem was to add labels for the inputs but hidden by 
CSS
/* Fix to pass Lighthouse: */
.label-hidden {
    position: absolute;
    height: 1px;
    width: 1px;
    clip: rect(1px,1px,1px,1px);
    border: 0;
    overflow: hidden
}
Another solution to the problem:
/* Fix to pass Lighthouse: */
label-hidden { 
    position: absolute; 
    top:-1000px; 
    left:-1000px; 
}

preconnect to required origins
Problem: Consider adding 
preconnect
or 
dns-prefetch
resource hints to establish early connections to important third-party origins. For example to pre-connect google analytics: 
https://www.google-analytics.com
we should include 
rel
attribute with 
preconnect
value:
<link rel="preconnect" href="https://www.google-analytics.com" crossorigin>
in 
head
tag

Guitar implements IMusician interface 
interface IMusician {
    public function play();
}

class Guitarist implements IMusician {
    public function play() { 
        echo "playin a guitar";
    }
}
In this example 
Guitarist
child class has to define 
play()
method because the child class implements interface 
IMusician
that has the method signature

abstract class can contain both methods with definitions and abstract methods 
abstract class Fruit { 
    private $color; 
    
    abstract public function eat(); 
    
    public function setColor($c) { 
        $this->color = $c; 
    } 
} 

class Apple extends Fruit {
    public function eat() {
        echo "Omnomnom";
    }
}

$obj = new Apple();
$obj->eat();
In this example an 
interface
would not be able to have method with definition, only method signatures are allowed in interfaces

HTTP request methods that HTML forms support
HTML forms only support 
GET
and 
POST
as HTTP request methods. A workaround for this is to tunnel other methods through 
POST
by using a 
hidden form field
which is read by the server and the request dispatched accordingly
<input type="hidden" name="_method" value="DELETE">
However, 
GET
, 
POST
, 
PUT
and 
DELETE
are supported by the implementations of XMLHttpRequest (i.e. AJAX calls) in all the major web browsers (IE, Firefox, Safari, Chrome, Opera)
