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";

}

案例二：

php动态批量上传文件

<?php

function upload_multi($path,$photo,$i){

$uploaddir = './'.$path;//文件存放目录

if(!file_exists($uploaddir))//如果目录不存在就新建

$uploaddir=mkdir($uploaddir);

$piece = explode('.',$photo['name'][$i]);

<input type="button" " name="add_img" value="新增上传" onclick="go_up()" /><br>

<input type="submit" value="Send" name="tijiao" /><br>

</p>

</form>

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, $alowexts = array()设置允许上传的类型，$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=8;

$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);

$fileext=strtolower(get_fileext($_files[$inputname]['name'][$key]));

}

if(!$this->isuploadedfile($tmp_name))

{

$this->error=12;

$this->error();

}

if(move_uploaded_file($tmp_name,$this->savepath.$savename) || @copy($tmp_name,$this->savepath.$savename))

{

//exit($this->savepath.$savename);

@chmod($savename, 0644);

@unlink($tmp_name);

$file_array[]=$this->savepath.$savename;

}

}

else

{

$this->error=$error;

$this->error();

}

unset($savename);

}

$this->files=$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 !',

12 => '非法上传文件 !',

13 => '最多可同时上传10个文件 !'

);

showmsg($upload_error[$this->error]);

}

}

//使用方法

new upload();

<?php

class upFiles

public $uploadFiles = array();

public $saveFilePath;

public $maxFileSize;

public $lastError;

public $allowType = array('gif','jpg','png','bmp');

public function __construct($file,$path,$size= 2097152,$type = '')

{

$this->uploadFiles = $file;

$this->saveFilePath = $path;

$this->maxFileSize = $size;

if($type != '') $this->allowType = $type;

}

public function upload()

{

for($i=0;$i<count($this->uploadFiles['name']);$i++)

{

//如果文件上传没有出现错误

if($this->uploadFiles['error'][$i] == 0)

{

//获取当前文件名,临时文件名,文件大小,扩展名

$name = $this->uploadFiles['name'][$i];

$tmpname = $this->uploadFiles['tmp_name'][$i];

$size = $this->uploadFiles['size'][$i];

$minetype = $this->uploadFiles['type'][$i];

private function getFileExt($filename)

{

$ext = pathinfo($filename);

return $ext['extension'];

}

private function getBaseName($filename,$type)

{

$basename = basename($filename,$type);

return $basename;

}

}

?>

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">



</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
