I tried your first suggestion and while it found and installed
pslist.exe with no problems at all, I never retrieved the memory usage,
or any memory usage:

if (!function_exists('memory_get_usage')) {
/**

* @access public
* @return long
* @see actual_path

Upgrade to client status of memory_get_usage() for use within Windows
XP Home
*/
function memory_get_usage() {
global $clientFolderPath;
$outputArray = array();
if (($_SERVER['windir'] || $_ENV['windir']) &&
@is_dir(actual_path(realpath("$clientFolderPath/win"))) &&

@is_file(actual_path(realpath("$clientFolderPath/win/pslist.exe")))
) {
exec('"' . actual_path($clientFolderPath) . '/win/pslist" -m ' .
getmypid(), $outputArray, $rc);
print_r(trim(substr($outputArray[8], 38, 10)) . " is your memory\n");

return trim(substr($outputArray[8], 38, 10));
} elseif ($_SERVER['windir'] || $_ENV['windir']) {
exec('tasklist /FI "PID eq ' . getmypid() . '" /FO LIST',
$outputArray);
return preg_replace( '/[\D]/', '', $outputArray[5] ) * 1024;
} else {
exec('ps -o rss -p ' . getmypid(), $outputArray);
return $outputArray[1] * 1024;
}
}
}

What do I need to be able to do this? This one lost me.

Sorry, no can do here either. win32ps.dll is only available for PHP
5.1.2 and PHP 6.0, there is no version for PHP 5.2.0 publically
available, thus, there is no match and PHP won't install the DLL file
as a result.
