Description

Introduced in PHP 8.0, nullsafe operators¹ enable you to safely use methods that may return null.

Syntax

class bar
{
    public function excellent(): string
    {
        return "excellent";
    }
}

class foo
{
    public function getBarOrNull(): ?bar
    {
        return rand(0, 1) === 1 ? new bar() : null;
    }
}

$foo = new foo();

echo $foo->getBarOrNull()?->excellent();
