php 生成自动创建文件夹并上传文件的示例代码_PHP教程

$uptypes=array('image/jpg','image/jpeg','image/png','image/pjpeg','image/gif','image/bmp','application/x-shockwave-flash','image/x-png');
$max_file_size=5000000;    //上传文件大小限制, 单位BYTE

  $addtime=date("Ymd",time());     
  $testdir="./".$addtime."/";  
  if(file_exists($testdir)):  
  else:  
  mkdir($testdir,0777);  
  endif;  

$destination_folder=$addtime."/"; //上传文件路径
$imgpreview=1;    //是否生成预览图(1为生成,其他为不生成);
$imgpreviewsize=1/2;   //缩略图比例

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
if (!is_uploaded_file($_FILES["Pic"][tmp_name]))
//是否存在文件
{
echo "文件不存在！";
exit;
}

$file = $_FILES["Pic"];
if($max_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 "只能上传图像文件或Flash！";
exit;
}

if(!file_exists($destination_folder))
 mkdir($destination_folder);
