PHP上传多文件，多图片程序代码

1.在同级目录下建立upload文件夹

2.将下面代码复制到upload.php中

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php   
 $uptypes=array(
//上传文件的ContentType格式
        'image/jpg',
        'image/jpeg',
        'image/png',
        'image/pjpeg',
        'image/gif',
        'image/bmp',
        'image/x-png',
		'application/msword',//doc
		'application/vnd.openxmlformats-officedocument.wordprocessingml.document',//docx
		'application/vnd.openxmlformats-officedocument.presentationml.presentation',//pptx 
		'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',//xlsx
		'text/plain'
                );
$max_file_size=2000000;     //上传文件大小限制, 单位BYTE
$dir="upload/";          //上传文件路径
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
   $file = $_FILES['upfile']['name'];
   foreach($file as $key=>$item){
   if($item != ''){
         if (!is_uploaded_file($_FILES['upfile']['tmp_name'][$key]))//是否存在文件
   	     {
            echo "图片不存在!";  
			exit;
         }
        if($max_file_size < $_FILES['upfile']['size'][$key])//检查文件大小
   	    {
            echo "文件太大!";
            exit;
        }
   if(!file_exists($dir))
       {
          mkdir($dir);
       }
    $filename=$_FILES['upfile']['tmp_name'][$key];
	$image_size = getimagesize($filename);
	$pinfo = pathinfo($file[$key]);

	$ftype = $pinfo['extension'];
	$destination = $dir.time().$file[$key];
    if (file_exists($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'];
    echo " <font color=red>已经成功上传</font><br>文件名:  <font color=blue>".$dir.$fname."</font><br>";
    echo " 宽度:".$image_size[0];
    echo " 长度:".$image_size[1];
    echo "<br> 大小:".$_FILES['upfile']['size']." bytes";

}				

	echo "<br>图片预览:<br>";
    echo "<img src=\"".$destination."\" width=".($image_size[0]*(1/4))." height=".($image_size[1]*(1/4));
    echo " alt=\"图片预览:\r文件名:".$destination."\r上传时间:\">";
	echo "<br>";
		}
	}

 ?>
<form method="post" enctype="multipart/form-data" action="" name="ff" id="ff" >
    <input type="file" name="upfile[]" />
    <input type="file" name="upfile[]" />
    <label>
      <input type="submit" name="submit" id="submit" value="按钮"/>
    </label>
 </form>

ps：上传时，需要上传两个。不然会报错，代码不是很完善，只是给出一个思路。自己可以根据此来编写代码
