使用文件句柄获取文件名（或删除文件）

Question

Is there a possibility to obtain filename from file handle? Or how can I delete file having only a handle?

Answer 1

There is stream_get_meta_data. It works for a stream that you get from tmpfile(). If you call it on a regular file pointer then you might only get the basename.

$meta_data = stream_get_meta_data($stream_or_file_pointer);
$filename = $meta_data["uri"];
echo $filename;

Example for tmpfile():

"/private/var/folders/v3/n54x13jx5v7610fw9dm0wcxm0000gn/T/phpCJvevP"

Example for fopen("somefile", "r"):

"test"
