PHP register_shutdown_function 1秒延迟

Question

我正在试图找出为什么PHP需要1秒才能执行register_shutdown_function。如果有办法克服这一点。

<?php

$start_time = microtime(true);

function shutdown($start_time)
{
    $time_diff = round(1000 * (microtime(true)-$start_time));
    echo $time_diff . "ms<br/>";
}

register_shutdown_function('shutdown', $start_time);
register_shutdown_function('shutdown', $start_time);
register_shutdown_function('shutdown', $start_time);
register_shutdown_function('shutdown', $start_time);
register_shutdown_function('shutdown', $start_time);

输出：

1001ms
2001ms
3003ms
4003ms
5003ms

在Windows / PHP上运行XAMPP 1.6.8：5.2.6
