If you were willing to include pslist inside your app's directory, you
could use it only when necessary, thus preserving portability. For
example:

if (substr(PHP_OS,0,3) == 'WIN') {
// Only run pslist on windows
exec(dirname(__FILE__) . '/win/pslist -m ' . getmypid(),
$lines, $rc);
[...]
} else {
// Something else for unix
}

Another way might be to use the win32 API functions and call
GetProcessMemoryInfo from psapi.dll. Here's an example of calling a
win32 function:

http://us2.php.net/manual/en/ref.w32api.php#39181

If you have the php_win32ps.dll extension loaded, you can could call
win32_ps_stat_proc(getmypid()).
