上传后调整图像权限 [英] Image permissions after uploading for resize

问题描述

我有一个用户的个人资料页面，其中用户从文件对话框上传他的个人资料图片。

I am having a user's profile page in which user uploads his profile picture from file dialog..

当文件移动到我的本地服务器的文件夹时，它获得了权限仅限0644 ..

when the file is moved to my local server's folder it gets permission as 0644 only..

但我希望在上传到服务器之前调整此图像的大小...

but I want to resize this image before getting uploaded into server...

为此，我需要获得0777的许可才能编辑它...

And for this I need permission as 0777 to edit it...

我应该怎么做..

这是我移动和调整大小的代码

here is my code for move and resize

  $upload_dir = './images';
  $tmp = $_FILES["img"]["tmp_name"];
  $names = $_FILES["img"]["name"];
  $res=$moveR=move_uploaded_file($tmp, "$upload_dir/$names");

  $a="./images/".$names;        
  list($width, $height) = getimagesize($a);
  $newwidth = "300"; 
  $newheight = "200";
  $thumb = imagecreatetruecolor($newwidth, $newheight);
  $source = imagecreatefromjpeg($a);
  imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
  imagejpeg($thumb, $a, 100);

提前致谢..

推荐答案

你需要在文件上运行：

chmod ($filepath, 0777);

在您的情况下可能：

chmod("$upload_dir/$names",0777);
