public function sayHelloTo($name)
{
$s = memory_get_usage();
$something = str_repeat($name, pow(1024, 2));
echo 'Inside: ';
echo memory_get_usage() - $s.PHP_EOL;
}
}
$reflectionMethod = new ReflectionMethod('HelloWorld', 'sayHelloTo');
$s = memory_get_usage();
$reflectionMethod->invoke(new HelloWorld(), 'a');
echo 'Outside: ';
echo memory_get_usage() - $s;
Expected result:
----------------
Inside: 1048760
