我的托管公司建议：

出于安全考虑，系统功能在我们的共享托管服务器上被阻止。请让您的开发人员使用其他方式上传文件。

我不懂编码，所以非常感谢你的帮助。

我在common.php文件中有这段代码

<?
$PageTitle = "MySite";
  $Default_Per_Upload_Image_Count = 6;
  $Image_Dir = "PrImage/";
  $Image_DirThumb = "Thmb_Image/";
  $Image_Dir2 = "images/PrImage/";
  $File_Max_Size = 5120;
  $File_Max_Size2 = 10240;
  $cm_WebSiteAddress = "http://master/cc/";
?>

Answer 1

您正在发出复制文件的系统调用：

system("cp $src_f $upfile");

PHP完全可以自己复制文件。该函数称为copy()。

Answer 2

检查您的php.ini文件并搜索disable_functions。您可以从列表中删除您想要的内容（包括system()函数。
