html で複数のファイルを指定，php でそれを move_upload_file ．

up_data.htm

<form enctype="multipart/form-data" action="up_data.php" method="POST">
    upload file:<br/>
    <input name="file_1" type="file" /><br/>
    <input name="file_2" type="file" /><br/>
    <input type="submit" value="send" />
    </form>

up_data.php

<?php
    if (!file_exists("./data")) {
        mkdir("./data") ;
        }
    foreach ($_FILES as $keys => $values) {
        $file_e = $values ;
        $tempfile =                $file_e[‘tmp_name’] ;
        $filename = ‘./data/’ .  $file_e[‘name’] ;
        if (is_uploaded_file($tempfile)) {
            move_uploaded_file($tempfile,$filename) ;
            }
        }
    $scan_f = scandir("./data") ;
    foreach ($scan_f as $key => $value) {
        echo $value . "<br/>\r\n" ;
        }
    ?>
