第一张图片

第二张图片

第三张图片

第四张图片

第五张图片








2、do_upload.php页面,即处理多文件上传的页面
复制代码 代码如下:

//全局数组$_FILES
//$_FILES['userfile']['tmp_name']文件在web服务器中临时存储的位置
//$_FILES['userfile']['name']用户系统中的文件名称
//$_FILES['userfile']['size']文件的字节大小
//$_FILES['userfile']['type']文件的MIME类型,text/plain,image/gif
//$_FILES['userfile']['error']与文件上载相关的错误代码
?>
//用for循环来获取传递的数据,是一个三维数据
for ($i=0;$i{
$upfile=$new_folder."/".$_FILES['userfile']['name'][$i];//此处可以根据自己的需要修改
if(move_uploaded_file($_FILES['userfile']['tmp_name'][$i],$upfile)){
echo "第".($i+1)."张图片上传成功
";
}
else{
echo "第".($i+1)."张图片上传不了
";
}
}
?>
