PHP 批量上传文件 大全
案例一：
<?php
$file_path="uploads/";
for($i=0;$i<count($_FILES[ufile][name]);$i++){
$_FILES[ufile][name][$i]=time().$_FILES[ufile][name][$i]; //加个时间戳防止重复文件上传后被覆盖
}
print_r($_FILES[ufile][name]);
$filename=$_FILES[ufile][name];
$filet=$_FILES[ufile][tmp_name];
if($filet[size]>"500000"){ //这个可以自己随便改
echo "您上传的文件大小为".$_FILES['ufile'][size]."大于500kb，请重新上传";
}else if($filet){
for($i=0;$i<count($filename);$i++){ //循环上传文件的数组
move_uploaded_file($filet[$i],$file_path.$filename[$i]);
}
}
else{
echo "文件上传失败";
}
?>

<?php

案例三：
php文件上传代码（支持文件批量上传）
本款文件上传类，默认是上传单文件的,我们只要修改$inputname ='files’为你的表单名就可以方便的实现批量文件上传了。 $savename = ''保存文件名, a l o w e x t s = a r r a y ( ) 设置允许上传的类型， alowexts = array()设置允许上传的类型， alowexts=array()设置允许上传的类型，savepath = ''保存路径。
*/
class upload
{
public $savepath;
public $files;
private $error;
function __construct($inputname ='files', $savepath = '', $savename = '', $alowexts = array(),$maxsize = 1024000)
{
if(!$alowexts)$alowexts=explode('|',upload_ftype);
$file_array=array();
$savepath=str_replace('','/',$savepath);
$savename=preg_replace('/[^a-z0-9_]+/i','',$savename);
$this->savepath=substr($savepath,-1)=='/'?$savepath:$savepath.'/'; //路径名以/结尾
if(!make_dir($this->savepath))
{

$this->error();
}
//exit($this->savepath);
if(!is_writeable($this->savepath))
{
$this->error=9;
$this->error();

if(sizeof($_files[$inputname]['error'])>10)
{
$this->error=13;
$this->error();
}
$max=sizeof($_files[$inputname]['error'])-1;
//exit($this->savepath.$savename);
foreach($_files[$inputname]['error'] as $key => $error)
{
if($error==upload_err_ok) //批量上传
{
$savename=$savename?$savename:date('ymdims').mt_rand(10000,99999);

else

$this->files=$file_array;
return true;
}
function isuploadedfile($file) //去掉系统自带的反斜线
{
return (is_uploaded_file($file) || is_uploaded_file(str_replace('\','',$file)));
}
function error()
{
$upload_error=array(0 => '文件上传成功 !',
1 => '上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值 !',
2 => '上传文件的大小超过了 html 表单中 max_file_size 选项指定的值 !',

案例五：php批量上传,里面没写上php的文件名们应该是：up.php
PHP批量上传文件
以下是本人做的一个批量上传的php程序，请参考！
首先，创建一个upload.html；内容如下：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; cha$resultet=utf-8" />
<title>
</title>
<script language="javascript">
function upload(id){
div = document.getElementByIdx_x_x('light');
div.style.display='block';
document.getElementByIdx_x_x('fade').style.display='block';
childs = div.childNodes;
for(i=0;i<childs.length;i++){
if(childs[i].nodeName.toUpperCase() == "IFRAME"){
childs[i].src="funs/up.php?label="+id;
}
}
}
//删除元素
function delpic(id){
a = document.getElementByIdx_x_x("pics");
child = document.getElementByIdx_x_x("span"+id);
a.removeChild(child);
}
//添加元素
function create(id){
span = document_createElement_x_x("span");
span.id = "span"+id;
span.style.display = "block";
span.style.height = "22px";
span.style.lineHeight = "22px";
span.innerHTML = "名称: <input type='text' name='pic_name[]' id='pic_name"+id +"' size='20'> 地址: <input type='text' name='pic_url[]' id='pic_url"+id +"' size='30'> [<a href='javascript:' onClick='upload("+id+")'><font color='#FF0000'>上传更换图片</font></a>] [<a href='javascript:delpic("+id+")'>移除</a>]";
return span;
}
function add_upload(){
div = document.getElementByIdx_x_x("pics");
mynum = parseInt(document.getElementByIdx_x_x("num").value,10);
//mynum = document.getElementByIdx_x_x("num").value;
document.getElementByIdx_x_x("num").value = mynum+1;
obj = create(mynum);
div.a(obj);
}
</script>
<style type="text/css">
.white_content {
display:none;
position:absolute;
width:40%;
top:25%;
left:30%;
z-index:9999;
background-color:#fff;
}
.black_overlay{
display:none;
width:100%;
height:100%;
background-color:#ccc;
position:absolute;
top:0;
left:0;
z-index:1;
filter: Alpha(opacity=50);
-moz-opacity:.5;
opacity:0.5;
}
</style>
</head>
<body>
<div id="light" class="white_content">
<div class="white_top"><a href="javascript:void(0)" onclick="document.getElementByIdx_x_x('light').style.display='none';document.getElementByIdx_x_x('fade').style.display='none'"> 关闭</a></div>
<iframe src="funs/up.php" width="100%" height="auto" scrolling="auto" frameborder="0" style="clear:both; padding-top:5px;"></iframe>
</div>
<div id="fade" class="black_overlay"></div>
<div class="right">
<div class="right_body">
<table class="tab">
<tr>
<td align="center">人物照片：
</td>
<td><div id="pics"> <span id="span0">名称:
<input type="text" size="20" id="pic_name0" name="pic_name[]">
地址:
<input type="text" size="30" id="pic_url0" name="pic_url[]">
[<a href="javascript:" onclick="upload(0)"><font color="#ff0000">上传更换图片</font></a>]</span>
<input type="button" value="添加上传文件" onclick="add_upload()" >
</div>
<input type="hidden" id="num" name="num" value="1" >
</td>
</tr>
</table>
</div>
</div>
</body>
</html>
然后在本目录创建一个funs的文件夹，人后在里面创建一个php文件,放在，内容如下：
//上传文件类型列表
$uptypes=array(
'image/jpg',
'image/jpeg',
'image/png',
'image/pjpeg',
'image/gif',
'image/bmp',
'image/x-png'
);
$max_file_size=2000000; //上传文件大小限制, 单位BYTE
$destination_folder="../uploadimg/"; //上传文件路径
?>
<html>
<head>
<title>添加上传图片</title>
<style type="text/css">
<!--
body
{
font-size: 12px;
margin:0px;
}
input, select, textarea { border:1px solid #CCC; font-size:12px; padding:2px; font-family:"宋体"; }
-->
</style>
</head>
<body>
<form enctype="multipart/form-data" method="post" name="upform">
<input name="upfile" type="file" size="30">
<input type="submit" value="上传"><br>
<span style="font-size:13px; color:#F00;">
允许上传的文件类型为：jpg, jpeg, png, pjpeg, gif, bmp, x-png</span>
</form>
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
if (!is_uploaded_file($_FILES["upfile"][tmp_name]))
//是否存在文件
{
echo "图片不存在!";
exit;
}
$file = $_FILES["upfile"];
if($max_file_size < $file["size"])
//检查文件大小
{
echo "文件太大!";
exit;
}
if(!in_array($file["type"], $uptypes))
//检查文件类型
{
echo "文件类型不符!".$file["type"];
exit;
}
if(!file_exists($destination_folder))
{
mkdir($destination_folder);
}
$filename=$file["tmp_name"];
$image_size = getimagesize($filename);
$pinfo=pathinfo($file["name"]);
$ftype=$pinfo['extension'];
$destination = $destination_folder.time().".".$ftype;
if (file_exists($destination) && $overwrite != true)
{
echo "同名文件已经存在了";
exit;
}
if(!move_uploaded_file ($filename, $destination))
{
echo "移动文件出错";
exit;
}
$pinfo=pathinfo($destination);
$fname=$pinfo[basename];
?>
<script type ="text/javascript">
<?php
if(isset($_GET['label'])){//如果是批量上传?>
window.parent.document.getElementByIdx_x_x("pic_name<?php echo $_GET['label']?>").value = "<?php echo $file["name"]?>";
window.parent.document.getElementByIdx_x_x("pic_url<?php echo $_GET['label']?>").value = 'uploadimg/<?php echo $fname?>';
window.parent.document.getElementByIdx_x_x('light').style.display='none';
window.parent.document.getElementByIdx_x_x('fade').style.display='none';
window.close();
<?php }
else{?>
window.parent.document.thisform.uploadfile.value='uploadimg/<?=$fname?>';
window.parent.document.getElementByIdx_x_x("success").innerHTML=("上传成功！ 宽度:<?=$image_size[0]?>px 长度:<?=$image_size[1]?>px 大小:<?=$file["size"].' '.bytes?>");
<?php }?>
</script>
<?
}
?>
</body>
完成，当然，在保存图片的时候可以自己添加保存缩略图的代码，具体自己扩展，仅供参考
