convert.php does not run in a screen session

I am trying to convert a big forum. At the moment I have to do this via ssh and start convert.php with "php5 -f convert.php -- $OPTIONS". But my internet connection is a bit buggy and so it is often killed.

If i start th开发者_如何学运维e above working command in a screen session it does not work. Instead php gives me the HTML code of the "convert.php" back.

head of the page:

Does it has something to do with the Sessions? But why does it work on the same ssh-connection without screen?

I cannot find any convert.php in the standard simple machines forum package. What conversion are you running exactly? Are you sure it is built to be used as a command line script?

Edit: you could try nohup php5 -f convert.php -- $OPTIONS & if you cannot use screen.

nohup -> don't kill the process after the current session dies

& -> run in the background
