It seems like array_merge($this->variables, array('expire' => time() + $expire)) of type array is incompatible with the declared type CodeBlog\RateLimit\type of property $variables.

$this->variables of type CodeBlog\RateLimit\type is incompatible with the type array expected by parameter $array1 of array_merge().
