Just wondering what smart people do for parsing data sent by the

In a normal form submit, the $_POST global nicely allocates form
elements as array elements automatically. But with the AJAX way, the
data get stuffed inside $HTTP_RAW_POST_DATA as a string, thereby
making extraction more tedious.
Call me crazy, but if AJAX is sending POST data correctly, your PHP
code shouldn't have to do anything special...
You're right in that "*IF* AJAX is sending POST data correctly"
everything is okay--that is, will $_POST contain the posted data as
array elements.
POST data is POST data.
The $HTTP_RAW_POST_DATA should be there as well, if you turned that
on, but that doesn't make $_POST go away.
Actually, that's not true. If the POST data is not set with the
correct headers...
http.setRequestHeader('Content-Type', 'application/x-www-form-
urlencoded');
http.setRequestHeader("Content-length", payload.length);
http.setRequestHeader("Connection", "close");
...then $_POST will be empty and the data that is sent can only be
accessed from $HTTP_RAW_POST_DATA (which incidentally is off by
default).
That was my problem--I wasn't sending those http headers. An earlier
poster pointed it out to me, and that solved the problem.
