if (is_dir($path) || mkdir($path,0777,true)) {

//判断文件是否为空或者出错
if ($upFile['error']==0 && !empty($upFile)) {

$filename = iconv("utf-8","gbk",$_FILES['file']['name']);
$date = date('Y-m-d',time());
$queryPath = './'.$dirpath.'/'.$date.'/'.$filename;
// 判断上传的是不是图片
if($_FILES['file']['type'] == 'image/jpeg' || $_FILES['file']['type']=='image/jpg'){
//move_uploaded_file将浏览器缓存file转移到服务器文件夹
if(move_uploaded_file($_FILES['file']['tmp_name'],$queryPath)){
$filename = iconv("utf-8","utf-8",$_FILES['file']['name']);
$queryPath = './'.$dirpath.'/'.$date.'/'.$filename;
echo $queryPath;
}
}
}
?>解决上传的图片文件名中文乱码：
$filename = iconv("utf-8","gbk",$_FILES['file']['name']);解决无法预览的问题:
$filename = iconv("utf-8","utf-8",$_FILES['file']['name']);html代码
