how can i copy more than one file in php?

Hello, proxomos:

There are several ways to do that, here is one version:

function my_copy($oldname, $newname)
  {
   if(is_file($oldname)){
     $perms = fileperms($oldname);
     return copy($oldname, $newname) && chmod($newname, $perms);
   }
   else if(is_dir($oldname)){
     my_dir_copy($oldname, $newname);
   }
   else{
     die("Cannot copy file: $oldname (it's neither a file nor a directory)");
   } 
  }
     
  function my_dir_copy($oldname, $newname) 
  {
   if(!is_dir($newname)){
     mkdir($newname);
   }
   $dir = opendir($oldname);
   while($file = readdir($dir)){
     if($file == "." || $file == ".."){
       continue;
     }
     my_copy("$oldname/$file", "$newname/$file");
   }
   closedir($dir);
  } 

You can use my_copy, which copies recursively the contents of one dir
into a target dir.

As I say, there are several ways to do it, so feel free to request for
any clarification.

Regards.
