🔗 PHP attributes in Laravel 13: The ultimate guide (36 new attributes!)

New Laravel 13 went all-in on PHP attributes. Properties like $fillable, $guarded, and $hidden that you've been defining on models for years can now be declared as class-level attributes: #[Fillable], #[Guarded], and #[Hidden]. The same applies to job configuration, console command signatures, middleware, and more.

In this article, I'll walk you through every PHP attribute available in Laravel 13 — both the new ones and those that existed before — with practical code examples for each.

Important notice: those attributes are optional, and you may use the old syntax in all those cases. The attributes are NOT breaking changes, just the new alternatives.
