多文件上傳其實就包括了圖片及各種文件了,下面介紹的是一款PHP多文件上傳類,一共兩個文件,upp.php 和 uploadFile.php,upp.php,這是前臺所顯示的表單文件了,默認的是四個上傳文件域,我們可以手動進行修改,另外這個頁面嵌套了 uploadFile.php 文件上傳類,下面一起來看例子.

php文件上傳例子,代碼如下:

<?php

header('content-type:text/html;charset=utf-8');

require('uploadFile.php');

if(isset($_POST['submit'])){

$uploads = $_FILES['file'];

$num_file = count($uploads['name']);

$up = new UploadFile($uploads,'uploads',1024);

$num = $up->upload();

if($num == $num_file ){

echo '全部文件上傳成功';

exit;

}else{

echo $num,'個文件上傳成功<br/>';

echo $up->showErrorInfo();

exit;

}

}

?>

PHP文件上傳類代碼,代碼如下:
