I'm wondering if it's possible to apply "lazy loading" to the $_POST
variable, so that processing only happens if and when it's requested.
That way you wouldn't need the ini setting.
In most cases, processing (=parsing) of the POST data already only occurs
when $_POST is requested; however, previously the data was already
entirely copied to two or three memory locations.
If you mean making it so that the data is only *read and processed* when
$_POST is requested, I suppose that would be possible, but I think it
would require significant code/architectural changes to PHP and to the
sapis. It would also raise other problems, including backwards
compatibility breaks, if we wanted the change to bring any benefit.
For instance, current scripts can, in POST requests, read any number of
times from php://input or $HTTP_RAW_POST_DATA (to simplify, let's say we
even let go $HTTP_RAW_POST_DATA). For this to be possible, you would have
to have the data in memory because you're reading from php://input the
first time, you can't know if it will be read a second time, so you either
break BC or keep everything in memory just in case there's a second read
-- and then you're where you started.
