This script takes some info from the database and then calls another PHP script using the System function (passing it some parameters).

I'm trying to get a list of comments that includes information about the touch stored in the touchtyp...
PHP, as we all know is very loosely typed. The language does not require you to specify any kind of type for function parameters or class variables. This can be a powerful feature. Sometimes though, it can make debugging your script a painful experience. For example, passing one kind of object into a method that expects a different kind...

I'm attempting to do an AJAX call (via JQuery) that will initiate a fairly long process. I'd like the script to simply send a response indicating that the process has started, but JQuery won't return the response until the PHP script is done running. I've tried this with a "close" header (below), and also with output buffering; neither ...
