you could read this
http://xdebug.org/docs/execution_trace
and then parse trace files to get the memory usage
create a global to store user functions, I think user function do not
populate get_defined_functions(); until the function is called;
$t = get_defined_functions();
$userFunctions = $t['u
Currently it's mostly procedural with some components that are OO. I
suspect most of the memory sinks are large arrays (we have a lot of
them), but I am not certain of that. Hence my interest in more accurate
investigation tools.

That's not really what I'm after. Let me try an example:
function foo($id) {
static $foos = array();
if (empty($foos[$id]) {
$foos[$id] = load_foo($id);
}
return $foos[$id];
}
When load_foo() is slow (e.g., lots of DB traffic or remote-server calls
or whatever), such caching can h
function check_memory_usage(&$memory)
{
$memory[] = memory_get_usage();
return $memory;
}
something like this?
you can put it wherever you like and returns an array for further
processing. You could optionally add a second argument to set the index
to a name and check if the name exists

Yep, I'm familiar with XDebug and KCacheGrind. As you say, though, it
doens't (as far as I am aware) offer the particular data that I'm after.
We've already got cachegrind gurus working on the code who know how to
use it better than I do. :-) What I'm looking for is "see this big
cache objec
ON Linux I have kcacheGrind setup with Xdebug and I find it is a nice
little thing to have. It won't tell you the memory consumed but it will
find cycles and display object maps. if you have Kcachegrind it is
likely you have valgrind installed.
