使用php将文件保存到不同的文件夹？

Question

我想知道打开文件后是否可以将文件保存到其他文件夹。我目前的逻辑是-

$myfile = $_POST['file']; // gets path of (in this case an image)
$size = getimagesize($myfile);  //for some reason I get an error message when this fails
// I'm assuming there is a better way of determining if the file is an image file or not.
if($size)
{
    //save file to said file path
}

Answer 1

试试：

if($size)
{
    copy($myfile, $newfile); //$newfile - with full path!
}
