Edit online: problem with Apple / Safari

There is a way to lock a file while accessing it in PHP. If two people did try to edit at the same time, one would simply fail.

Thanks John. Do you know how to do that? If not, I'll google around.

In PHP 5+ if using the the file_put_contents function (combines file handle, file open and write from previous versions) to write to the file, you can use the LOCK_EX flag to prevent any other attempts at writing to the file during the operation. See:

http://php.net/manual/en/function.file-put-contents.php

Just opening and writing to a file is more complex in PHP 4, but I believe a similar thing can be done during the write phase.

Thank you so much, John! I'm indeed using file_put_contents.
