この RFC は4種類のスカラー型、int、float、string と bool の新しい型宣言の追加を提案します。これらの型宣言は PHP 関数が使う既存のメカニズムと同じようにふるまいます。
この RFC はファイル単位でオプションの新しいディレクティブである declare(strict_types=1); をさらに追加することを提案します。このディレクティブによって、エクステンションとビルトインの PHP 関数を含む、すべての関数呼び出しと戻り値の宣言は "strict" なスカラー型の宣言に対して型チェックがなされます。さらに、このディレクティブを伴うエクステンションとビルトインの PHP 関数の呼び出しによって、パラメーター解析が失敗した段階において、E_RECOVERABLE_ERROR が生成され、これらの関数とユーザーランドの型宣言との協調がもたらされます。
これら2つの機能によって、PHP のプログラムは正しく動き、読み書きの前提知識を減らすことができます (self-documenting)。
