$m = new MemoryStat(true);

// Example array
$a = array();
$b = array();

// add first checkpoint
$m->addCheckpoint('first checkpoint');

// get current memory limit from ini_get('memory_limit')
echo 'Memory limit raw: '.$m->getMemoryLimitRaw().PHP_EOL; // 536870912
// get current memory limit formatted from ini_get('memory_limit')
echo 'Memory limit: '.$m->getMemoryLimit().PHP_EOL; // 512M
// get current memory usage
