In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:
class MyClass { } $x = new MyClass(); $x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:
class MyClass { public $foo; } $x = new MyClass(); $x->foo = true;
return ! ! $role->intersect($this->roles)->count();
* Determine if the user may perform the given permission.
* @param Permission $permission
public function hasPermission(Permission $permission)
return $this->hasRole($permission->roles);
