<?php
// Original from http://php.net/memory_get_usage by
websjwans at hotmail dot com. Thanks alot!
if ( ! function_exists( 'memory_get_usage' ) ):
// Only define function if it doesn't exist
function memory_get_usage()
{
// If we are running on Windows
if ( substr( PHP_OS, 0, 3 ) == 'WIN' ):
$output = array();
// Should check whether tasklist is available, but I'm lazy
exec( 'tasklist /FI "PID eq ' . getmypid() . '" /FO LIST', $output
);
// Filter non-numeric characters from output. Why not use substr & strpos?
// I'm running Windows XP Pro Dutch, and it's output does not match the
// English variant, as will all other translations. This is a more generic
// approach, and has a better chance of actually working
return preg_replace( '/[^0-9]/', '', $output[5] ) * 1024;
// Tasklist outputs memory usage in kilobytes, memory_get_usage in bytes.
// So we multiply by 1024 and in the process convert from string to integer.

return false;

Works for me. Functionality should match memory_get_usage(), albeit slower (exec & regex). Have
fun!
