Multiple file upload in php
それは言われている：これは、この質問の重複であると何度も尋ねたと回答されていますこの答えにもう少し追加してください。この日や年齢では、単にファイルをアップロードするだけではありません。おそらく、データベースにレコードを保存したり、ページのリロード後にビューにいくつかの統計情報を表示したりすることができます。これを行うには、あなたが実際にアップロードを行うことができるクラス/メソッドシステム（私の意見では）を使う必要がありますが、役に立つ情報を取り戻す必要があります。 フレームワークがあなたのためにこのすべての世話をする（！そしてもっと）が、この答えのために、ここでは簡単な例であるだろう、多分それはあなたのアイデアを与えるだろう。
