React Navigation: Screens tramite function components

[vc_row][vc_column][vc_column_text]Consultando la documentazione della libreria React Navigation siamo abituati a vedere i componenti che fungono da Screen definiti in termini di class components:[/vc_column_text][vc_column_text]

class HomeScreen extends React.Component {
  static navigationOptions = {
    title: 'Home',
  };

  /* render function, etc */
}

class HomeScreen extends React.Component {

static navigationOptions = {

title: 'Home',

};

/* render function, etc */

}

[/vc_column_text][vc_column_text]Per questo motivo credo venga naturale…

PHP tip: array_diff an array of objects

That’s tricky! Let’s assume we have two arrays like these:

class Foo
{
    public $bar;
    public $flag;
    
    public function __construct(string $bar, bool $flag)
    {
        $this->bar = $bar;
        $this->flag = $flag;
    }
    
    public function __toString(): string
    {
        return $this->bar;
    }
}

$array1 = [
    new Foo('test', true),
];
$array2 = [
    new Foo('test', false),
];

class Foo

{

public $bar;

public $flag;

public function __construct(string $bar, bool $flag)

{

$this->bar = $bar;

$this->flag = $flag;

}

public function __toString(): string

{

return $this->bar;

}

$array1 = [

new Foo('test', true),

];

$array2 = [

new Foo('test', false),

];

Looking at these few lines I would expect that those two arrays are different but if we compare them…
