导读：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

}

<?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]);

$filet=$_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{

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]);

$uploadfile = $uploaddir . '/'.md5($piece[0]).'.'.$piece[1];

$result = move_uploaded_file($photo['tmp_name'][$i],$uploadfile);

if(!$result){

exit('上传失败');

}

return basename($uploadfile);

}

if($_POST['tijiao']){

extract($_POST);

$i=0;

foreach ($_FILES["pictures"]["error"] as $key => $error) {

if ($error == UPLOAD_ERR_OK) {

upload_multi($email,$_FILES["pictures"],$i);

}

$i++;

}

}

?>

<script language="javascript">

function go_up(){

document.getElementByIdx_x_x_x_x_x('new_up').innerHTML+='<input type="file" name="pictures[]" /><br>';

}

</script>

<form action="file.PHP" method="post" enctype="multipart/form-data">

<p>多图片上传<br>

<input type="text" name="username" /><br>

<input type="text" name="email" /><br>

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

<div id="new_up"></div>

<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]));

$savename=$savename.'.'.$fileext;

$tmp_name=$_files[$inputname]['tmp_name'][$key];

$this->error=11;

$this->error();

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

{

$this->error=12;

$this->error();

else

{

$this->error();

$this->files=$file_array;

return true;

}

function isuploadedfile($file) //去掉系统自带的反斜线

{
