Questions:
After I do:
$temp = tmpfile();
fwrite($temp, "writing to tempfile");
I’d like to get a full path to the $temp file that tmpfile has created.
What do I need to do to get that information?
How to&Answers:
$path = tempnam(sys_get_temp_dir(), 'prefix');
See this example.
Answer：
tmpfile returns a stream-able file pointer.
To get the corresponding path, ask the stream for its meta data:
$file = tmpfile();
$path = stream_get_meta_data($file)['uri']; // eg: /tmp/phpFx0513a
The benefit of the tmpfile approach? PHP automatically removes the $path when $file goes out of scope. With tempnam, you must manually remove the created file.
