Dear Eric,
I have tried your latest gist, edited for my environment as shown below. The result was a timeout in the browser, with eventual error message "The connection to the server was reset while the page was loading."
When I add "exit;" after the call to ssh2_connect, the result is instant execution, with no output.
When I move the "exit;" to after the call to ssh2_auth_pubkey_file, the result is instant execution, with no output.
When I move the "exit;" to after the call to ssh2_sftp, the result is instant execution, with no output.
So the timeout happens either in the file_exists call or the copy call.
I don't know how to do any other debugging.
Please help further.
