StrictObject & Any — Undefined Property Guards

StrictObject (abstract)

Extend StrictObject to immediately catch typos and dynamic property access. It overrides __get, __set, __isset, and __unset to throw RuntimeException instead of silently creating or returning null.

abstract class StrictObject { ... }

Errors caught at runtime:

class Config extends StrictObject {
    public string $host = 'localhost';
}

$c = new Config();

echo $c->host;   // OK — declared property
echo $c->hoost;  // RuntimeException: Attempt to read undefined property 'hoost'

$c->host  = 'db';    // OK
$c->extra = 'val';   // RuntimeException: Attempt to write undefined property 'extra'

isset($c->undef);    // RuntimeException: Cannot use isset() on undefined property 'undef'
unset($c->undef);    // RuntimeException: Cannot use unset() on undefined property 'undef'

Any (abstract) — extends StrictObject

Any (BaseObject) adds a __toString() implementation that returns ClassName@{objectId}, useful for logging and debugging.

abstract class Any extends StrictObject {
    public function __toString(): string { ... }
}

class User extends Any {
    public function __construct(public readonly string $name) {}
}

$u = new User('Alice');
echo $u;    // User@42

Global aliases

// bootstrap.php registers these automatically:
class_alias(\core\StrictObject::class, 'StrictObject');
class_alias(\core\Any::class, 'BaseObject');

Use BaseObject as the base for all domain entities:

class OrderLine extends BaseObject {
    public function __construct(
        public readonly Product $product,
        public readonly int     $quantity,
        public readonly float   $unitPrice,
    ) {}
}
