codeigniter multiple upload

Question

イメージをアップロードするたびに3つのイメージをアップロードしようとしていますが、イメージ名を配列imagesに入れていますが、メソッドの最後には、print_r($images)しか取得できません。アップロードされた最後の画像の名前、誰でもこの理由を教えてもらえますか？ここで

バディ、私のコードで私はあなたがHTMLを書かれているかどうかはわかりませんが、サンプルコードの下にしてみてください。 1つのtest.phpファイルを作成してデモを確認し、必要に応じてコード内のロジックを複製することができます。

<?php 
    if($_POST) 
    { 
     print "<pre>";print_r($_FILES);print "</pre>"; 
    } 
?> 
<form name="frm" method="post" enctype="multipart/form-data"> 
File1 : <input type="file" name="images[]" id="images[]"/> <br> 
File2 : <input type="file" name="images[]" id="images[]"/> <br> 
File3 : <input type="file" name="images[]" id="images[]"/> <br> 
<input type="submit" name="Submit" /> 
</form> 

と出力は、私は、問題の同じ種類を持っていた
