概述

复制代码代码如下:

    <form action="uploads.php" method="post" enctype="multipart/form-data">
        <input type="file" name="file[]">
        <br>
        <input type="file" name="file[]">
        <br>

        <br>
        <input type="file" name="file[]">
        <br>
        <input type="file" name="file[]">
        <br>

index_uploads.php

<?php
    echo "<pre>";
    print_r($_FILES);
    echo "</pre>";

$count = count($_FILES['file']['name']);

    for ($i = 0; $i < $count; $i++) {
        $tmpfile = $_FILES['file']['tmp_name'][$i];
        $filefix = array_pop(explode(".", $_FILES['file']['name'][$i]));
        $dstfile = "uploads/files/".time()."_".mt_rand().".".$filefix;

        if (move_uploaded_file($tmpfile, $dstfile)) {
            echo "<script>alert('succeed!');window.location.href='listdir.php';</script>";
        } else {
            echo "<script>alert('fail!');window.location.href='index_uploads.php';</script>";
        }
    }
