这段代码给了我作为图像的文件，我想做的是将这些图像移动到适当的文件夹中。例如，对于文件的缩略图thumbnail.png，我想将此文件移动到images/thumbnails/thumbnail.png文件夹中。我该怎么做？我认为有move_uploaded_file但不确定如何，因为如果特定文件不是图像，请离开它并移动到下一个文件。例如，下一个文件desktop1280x800不是图像，因此它将跳过并移动到下一个桌面文件以将其移动到目录（如果它是图像）。所以我不能按顺序完成我猜..下面是移动这些文件的代码，我只想移动特定的文件而不是全部
if(move_uploaded_file($_FILES[$thumbnail_fieldname]['tmp_name'], $thumbnail_filename)
//move desktop files
&& in_array(TRUE, array(
move_uploaded_file($_FILES[$desktop_fieldname_1280x800]['tmp_name'], $desktop_filename_1280x800),
move_uploaded_file($_FILES[$desktop_fieldname_1366x768]['tmp_name'], $desktop_filename_1366x768),
move_uploaded_file($_FILES[$desktop_fieldname_1920x1080]['tmp_name'], $desktop_filename_1920x1080)))){
//Files moved.
}
$type = $_FILES[$desktop_fieldname_1280x800]['type'];
if(strpos($type, 'image') !== false)
{
//code
}
另类
$filename_parts = explode('.', $_FILES[$desktop_fieldname_1280x800]['tmp_name']);
$ext = strtolower(end($filename_parts));
$autorized = array('png', 'jpeg', 'jpg', 'gif', 'bmp' ); // ...
if(in_array($ext, $autorized))
{
//code
}
或两者兼而有之。
