In PHP 8 and later versions, you can index objects using various features like the nullsafe operator, property promotion, and more. Here's a brief overview of how to work with objects and arrays in a more efficient manner with PHP 8+.
PHP 8 introduced a number of enhancements to object handling that made it easier to manipulate and access object properties directly.
// Example of property promotion in PHP 8
class User {
public function __construct(
public string $name,
public string $email,
public array $roles = []
) {}
}
// Create a new User object
$user = new User("John Doe", "john@example.com", ["admin", "editor"]);
// Accessing the properties directly
echo $user->name; // Outputs: John Doe
echo $user->email; // Outputs: john@example.com
print_r($user->roles); // Outputs: Array ( [0] => admin [1] => editor )
// Using the nullsafe operator
$emailDomain = $user->roles[0]->getEmail() ?? 'Email not available'; // Avoids errors when properties are null
