test:

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only wit...

Parse DateTime string in JavaScript

is_file or file_exists in PHP

is_file() is the fastest, but recent benchmark shows that file_exists() is slightly faster for me. So I guess it depends on the server.

...subject, $message, $headers); // $recipient should be $to
